• CVE-2026-63033 • published on July 30, 2026 A crafted IEC 60870-5-104 I-frame with a declared object count exceeding what fits in the ASDU body causes InformationObject_ParseObjectAddress to read one byte past the end of the heap-allocated message buffer.

• CVE-2026-10031 • published on July 30, 2026 SFTPGo prior to 2.7.4 contains a permission bypass vulnerability that allows authenticated users to circumvent per-directory access controls by creating symbolic links in a permitted directory that point to files in directories where download, upload, or overwrite permissions are denied. Attackers can exploit the create_symlinks permission combined with read and write access in one directory to read or modify files in restricted directories, as operations are authorized against the link's directory permissions rather than the dereferenced target's directory permissions.

• CVE-2026-66720 • published on July 30, 2026 The GOOSE subscriber component improperly validates the UTC timestamp field in unauthenticated IEC 61850 GOOSE (EtherType 0x88B8) Layer-2 multicast messages. A specially crafted GOOSE frame containing an undersized timestamp field can trigger a heap out-of-bounds read during message processing, causing the process to crash and resulting in a denial-of-service condition.

• CVE-2026-66369 • published on July 30, 2026 The GOOSE parser contains an off-by-one boundary-handling flaw that can be triggered by a single unauthenticated Layer-2 multicast frame on the process bus. When specific GOOSE message fields are processed, the parser advances its internal buffer position incorrectly, resulting in a heap out-of-bounds read. On affected platforms, this condition reliably terminates the subscriber process and causes a denial-of-service.
