CVE-2026-47269

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.0, pamusb's denyremote feature checks utmpx utaddrv6 to detect whether an authentication request originates from a remote session. The outer guard was if utent-utaddrv60 != 0, which only tests the first...

CVE-2026-47269 pam_usb: deny_remote feature incorrectly classifies IPv4-mapped IPv6 remote connections as local

pamusb provides hardware authentication for Linux using ordinary removable media. Prior to 0.9.0, pamusb's denyremote feature checks utmpx utaddrv6 to detect whether an authentication request originates from a remote session.

CVE-2026-47269

CVE-2026-47269 affects pam_usb on Linux. The deny_remote feature checks utmpx ut_addr_v6[0] to identify remote sessions, but IPv4-mapped IPv6 addresses cause the check to fail (ut_addr_v6[0] == 0, while the IPv4 address is in ut_addr_v6[3]), so remote SSH connections can be treated as local. As a...

GHSA-CQP8-FCVH-X7R3 Pydantic AI: SSRF cloud-metadata blocklist bypass via IPv4-mapped IPv6 (Incomplete fix of CVE-2026-25580)

Summary When an application using Pydantic AI opts a URL into forcedownload='allow-local' which disables the default block on private/internal IPs, the cloud-metadata blocklist could be bypassed by encoding the metadata IP in an IPv6 transition form IPv4-mapped IPv6, 6to4, or NAT64. Dual-stack an...

CVE-2026-43929

ssrfcheck is a library that checks if a string contains a potential SSRF attack. In 1.3.0 and earlier, ssrfcheck fails to block Server-Side Request Forgery attacks when the target private IP address is encoded as an IPv4-mapped IPv6 address e.g. http://::ffff:127.0.0.1/. The WHATWG URL parser bui...
