Recent Vulnerabilities

• CVE-2026-72575 • published on August 10, 2026 An improper authorization vulnerability in daptin through v0.12.34 allows unauthenticated remote attackers to read, create, update, and delete usergroup records. The permission check functions (CanRead, CanPeek, CanCreate, CanUpdate, CanDelete, CanRefer) in server/permission/permission.go return true whenever p.UserId equals the requesting userId, but fail to reject the null/zero reference — unlike CanExecute, which explicitly guards it.
• CVE-2026-72574 • published on August 10, 2026 A host header injection vulnerability in picocms/Pico through 2.1.4 allows an unauthenticated remote attacker to control the origin of JavaScript and CSS assets loaded by the default theme. When base_url is unset (the default), Pico::getBaseUrl in lib/Pico.php builds the base URL from unvalidated Host, X-Forwarded-Host, X-Forwarded-Proto, and X-Forwarded-Port request headers.
• CVE-2026-72573 • published on August 10, 2026 An OS command injection vulnerability in 4xmen/pm2panel (all versions) allows an authenticated remote attacker to execute arbitrary system commands on the host. The pm2panel.js handler at line 188 passes the unsanitized req.query.id parameter directly to exec('pm2 restart ' + id) without input validation or shell escaping, enabling command chaining via semicolons or other shell metacharacters.
• CVE-2026-72556 • published on August 11, 2026 A remote code execution vulnerability in ZoneMinder 1.39.17 allows any authenticated user to execute OS commands by exploiting a broken permission check in the Filter class. The canEdit() and canDelete() methods invoke nonexistent methods on the ZM\User class, causing PHP __call() to return a truthy value that bypasses the permission check for all users. Any authenticated user can trigger filter-based OS command execution regardless of their assigned role.
• CVE-2026-72555 • published on August 11, 2026 A broken access control vulnerability in Peppermint Lab Peppermint through commit ba6e217 exists because the Config.roles_active flag defaults to false, causing all permission checks on ticket, client, and user handlers to behave as no-ops on default installations. All authenticated users bypass ownership and administrative access controls. An attacker with any user account can read, modify, or delete tickets, clients, and users belonging to any other account.
• CVE-2026-72550 • published on August 11, 2026 An SQL injection vulnerability in Friendica through the 2026.08-dev branch allows unauthenticated remote attackers to execute arbitrary SQL statements via the photo-view order parameter. The parameter is concatenated unescaped into a SHOW COLUMNS query via a bare PDO::query() call, enabling stacked statement injection. An unauthenticated attacker can read, modify, or delete the entire database.
• CVE-2026-72548 • published on August 11, 2026 An information disclosure vulnerability in OpenSignLabs OpenSign through 2.37.0 allows unauthenticated remote attackers to retrieve any organisation tenant record via the gettenant Parse cloud function. The function accepts a contactId parameter and returns the full tenant record without authentication or authorization checks. An attacker can enumerate and disclose tenant configuration data for any organisation in the system.
• CVE-2026-72547 • published on August 11, 2026 An insecure direct object reference vulnerability in Attendize through commit 9289acb allows any authenticated event organiser to bulk import attendees into events belonging to other accounts via the postImportAttendee endpoint. The endpoint loads the target event by ID without verifying ownership against the requesting organiser account. An attacker can inject bulk attendee data into any event in the system regardless of account boundaries.
• CVE-2026-72546 • published on August 11, 2026 An insecure direct object reference vulnerability in Attendize through commit 9289acb allows any authenticated event organiser to inject attendees and orders into events belonging to other accounts via the postInviteAttendee endpoint. The endpoint loads the target event by ID without scoping the query to the authenticated organiser account. An attacker can modify event data and financial records across account boundaries.
• CVE-2026-72541 • published on August 11, 2026 A missing authorization vulnerability in Windmill Labs Windmill through 1.783.0 allows any authenticated workspace member to overwrite any resource type schema via the update_resource_type endpoint. The endpoint omits the administrator permission check that the corresponding delete_resource_type endpoint enforces. An attacker with workspace member privileges can corrupt resource type definitions, breaking workflows that depend on them.
• CVE-2026-72538 • published on August 11, 2026 An argument injection vulnerability in PrefectHQ Prefect through 3.8.2 allows authenticated users to achieve remote code execution via the git_clone pull step branch field. The branch parameter is passed directly to git pull without sanitization, enabling injection of arbitrary git arguments. This represents a distinct code path from the incomplete fix applied for CVE-2026-5366 and allows command execution on the Prefect server.
• CVE-2026-72502 • published on August 15, 2026 In the Linux kernel, the following vulnerability has been resolved: tcp: ipv6: clamp default adverting MSS to avoid GSO_BY_FRAGS (0xFFFF) When MTU is large, ip6_default_advmss() can return IPV6_MAXPLEN (65535). This is interpreted by TCP as mss_clamp, allowing the MSS to reach 65535. However, 0xFFFF is also used as a magic value GSO_BY_FRAGS in the kernel. If a TCP packet with gso_size=0xFFFF is passed to skb_segment(), it will be mistakenly treated as GSO_BY_FRAGS, leading to a NULL pointer dereference because local TCP packets do not use frag_list. Fix this by returning min(IPV6_MAXPLEN, GSO_BY_FRAGS - 1) (65534) from ip6_default_advmss() when MTU is large. Also update the stale comment in ip6_default_advmss() which suggested that IPV6_MAXPLEN is returned to mean "any MSS".
• CVE-2026-72494 • published on August 15, 2026 In the Linux kernel, the following vulnerability has been resolved: RDMA/irdma: Replace waitqueue and flag with completion The driver previously used a waitqueue along with an explicit request_done flag, but without proper barriers around request_done. An earlier patch by Gui-Dong Han hanguidong02@gmail.com attempted to fix this by adding the missing memory barriers. Rather than adding the barriers, this patch replaces the waitqueue+flag with a completion, which is designed for this exact purpose.
• CVE-2026-72493 • published on August 15, 2026 In the Linux kernel, the following vulnerability has been resolved: net: serialize netif_running() check in enqueue_to_backlog() Syzbot reported a KASAN slab-use-after-free in fib_rules_lookup(). The root cause is a race condition where packets can escape the backlog flushing during device unregistration (e.g., during netns exit). Commit e9e4dd3267d0 ("net: do not process device backlog during unregistration") introduced a lockless netif_running() check in enqueue_to_backlog() to prevent queuing packets to an unregistering device. However, this creates a TOCTOU race window. A lockless transmitter (like veth_xmit) can pass the check before dev_close() clears IFF_UP. If the transmitter is then delayed, flush_all_backlogs() can run and finish before the transmitter grabs the backlog lock and queues the packet. The packet then escapes the flush and triggers UAF later when processed. Fix this by moving the netif_running() check inside the backlog lock. This serializes the check with the flush work (which also grabs the lock). We then either queue the packet before the flush runs (so it gets flushed), or check netif_running() after the flush/close completes (so it gets dropped).
• CVE-2026-72491 • published on August 15, 2026 In the Linux kernel, the following vulnerability has been resolved: net/9p: fix race condition on rdma-state in trans_rdma.c The rdma->state field is modified without holding req_lock in both recv_done() and p9_cm_event_handler(), while rdma_request() accesses the same field under the req_lock spinlock. This inconsistent locking creates a race condition: - recv_done() running in softirq completion context sets rdma->state = P9_RDMA_FLUSHING without acquiring req_lock - p9_cm_event_handler() modifies rdma->state at multiple points (ADDR_RESOLVED, ROUTE_RESOLVED, ESTABLISHED, CLOSED) without req_lock - rdma_request() uses spin_lock_irqsave(&rdma->req_lock, flags) to protect the read-modify-write of rdma->state The race can cause lost state transitions: recv_done() or the CM event handler could set state to FLUSHING/CLOSED while rdma_request() is concurrently checking or modifying state under the lock, leading to the FLUSHING transition being silently overwritten by CLOSING. This corrupts the connection state machine and can cause use-after-free on RDMA request objects during teardown. Fix by adding req_lock protection to all rdma->state modifications in recv_done() and p9_cm_event_handler(), matching the pattern already used in rdma_request(). Use spin_lock_irqsave/spin_unlock_irqrestore in the CM event handler since it can race with recv_done() which runs in softirq context. Tested with a kernel module that races two threads (simulating rdma_request and recv_done/CM handler) on rdma->state with proper locking: 5.5M+ FLUSHING writes over 27M iterations with 0 lost transitions.
• CVE-2026-72487 • published on August 15, 2026 In the Linux kernel, the following vulnerability has been resolved: PCI: Check ROM header and data structure addr before accessing We meet a crash when running stress-ng on x86_64 machine: BUG: unable to handle page fault for address: ffa0000007f40000 RIP: 0010:pci_get_rom_size+0x52/0x220 Call Trace: TASK pci_map_rom+0x80/0x130 pci_read_rom+0x4b/0xe0 kernfs_file_read_iter+0x96/0x180 vfs_read+0x1b1/0x300 Our analysis reveals that the ROM space's start address is 0xffa0000007f30000, and size is 0x10000. Because of broken ROM space, before calling readl(pds), the pds's value is 0xffa0000007f3ffff, which is already pointed to the ROM space end, invoking readl() would read 4 bytes therefore cause an out-of-bounds access and trigger a crash. Fix this by adding image header and data structure checking. We also found another crash on arm64 machine: Unable to handle kernel paging request at virtual address ffff8000dd1393ff Mem abort info: ESR = 0x0000000096000021 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 FSC = 0x21: alignment fault The call trace is the same with x86_64, but the crash reason is that the data structure addr is not aligned with 4, and arm64 machine report "alignment fault". Fix this by adding alignment checking. [bhelgaas: shorten function names, wrap comments]
• CVE-2026-72482 • published on August 15, 2026 In the Linux kernel, the following vulnerability has been resolved: gpib: fix double decrement of descriptor_busy in command_ioctl() commit d1857f8296dc ("gpib: fix use-after-free in IO ioctl handlers") introduced a descriptor_busy reference counter to pin struct gpib_descriptor across IO ioctl operations. In command_ioctl(), the error path inside the loop decrements descriptor_busy and breaks, but execution then falls through to the unconditional decrement after the loop, underflowing the counter to -1. This re-enables the use-after-free that the original fix was meant to prevent: a concurrent close_dev_ioctl() sees descriptor_busy == 0 on an actively-used descriptor and frees it. Remove the early decrement from the error path. The post-loop decrement already handles all exit paths, matching the correct pattern used in read_ioctl() and write_ioctl().
• CVE-2026-72475 • published on August 15, 2026 In the Linux kernel, the following vulnerability has been resolved: dmaengine: dma-axi-dmac: Properly free struct axi_dmac_desc Use axi_dmac_free_desc() to free fully the descriptor at fail path when call axi_dmac_alloc_desc() in axi_dmac_prep_peripheral_dma_vec().
• CVE-2026-72474 • published on August 15, 2026 In the Linux kernel, the following vulnerability has been resolved: dmaengine: dma-axi-dmac: use DMA pool to manange DMA descriptor For architectures like Microblaze or arm64 (where this IP is used), DMA_DIRECT_REMAP is set which means that dma_alloc_coherent() might remap (and hence vmalloc()) some memory. This became visible in a design where dma_direct_use_pool() is not possible. With the above, when calling dma_free_coherent(), vunmap() would be called from softirq context and thus leading to a BUG(). To fix it, use a dma pool that is allocated in .device_alloc_chan_resources() and allocate blocks from it. The key point is that now dma_pool_free() is used in axi_dmac_free_desc() to free the blocks and that just frees the blocks from the pool in the sense they can be used again. In other words, no actual call to dma_free_coherent() happens. That only happens when destroying the pool in axi_dmac_free_chan_resources() which does not happen in any interrupt context.
• CVE-2026-72472 • published on August 15, 2026 In the Linux kernel, the following vulnerability has been resolved: nfs: use nfsi-rwsem to protect traversal of the file lock list Lingfeng identified a bug and suggested two solutions, but both appear to have issues. Generally, we cannot release flc_lock while iterating over the file lock list to avoid use-after-free (UAF) problems with file locks. However, functions like nfs_delegation_claim_locks and nfs4_reclaim_locks cannot adhere to this rule because recover_lock or nfs4_lock_delegation_recall may take a long time. To resolve this, NFS switches to using nfsi->rwsem for the same protection, and nfs_reclaim_locks follows this approach. Although nfs_delegation_claim_locks uses so_delegreturn_mutex instead, this is inadequate since a single inode can have multiple nfs4_state instances. Therefore, the fix is to also use nfsi->rwsem in this case. Furthermore, after commit c69899a17ca4 ("NFSv4: Update of VFS byte range lock must be atomic with the stateid update"), the functions nfs4_locku_done and nfs4_lock_done also break this rule because they call locks_lock_inode_wait without holding nfsi->rwsem. Simply adding this protection could cause many deadlocks, so instead, the call to locks_lock_inode_wait is moved into _nfs4_proc_setlk. Regarding the bug fixed by commit c69899a17ca4 ("NFSv4: Update of VFS byte range lock must be atomic with the stateid update"), it has been resolved after commit 0460253913e5 ("NFSv4: nfs4_do_open() is incorrectly triggering state recovery") because all slots are drained before calling nfs4_do_reclaim, which prevents concurrent stateid changes along this path. Also, nfs_delegation_claim_locks does not cause this concurrency either since when _nfs4_proc_setlk is called with NFS_DELEGATED_STATE, no RPC is sent, so nfs4_lock_done is not called. Therefore, nfs4_lock_delegation_recall from nfs_delegation_claim_locks is the first time the stateid is set.
