CVE-2026-101087: Server-Side Request Forgery (SSRF)

Nezha versions 2.0.10 through 2.3.2 use a restricted HTTP client to validate user-configurable notification and DDNS webhook URLs, but the denylist did not cover IPv6 transition ranges — specifically the 6to4 prefix 2002::/16 and the local-use IPv4/IPv6 translation prefix 64:ff9b:1::/48. Because...

Astra Linux – Vulnerability in Linux 6.12

In the Linux kernel, the following vulnerability has been resolved: ipv6: Proper accounting of fraggap on the paged allocation path In ip6.AppendData, when the paged-allocation branch is taken MSGMORE / NETIFFSG / large fraglen, alloclen and pagedlen are computed as follows: alloclen =...

SUSE CVE-2026-98102

In the Linux kernel, the following vulnerability has been resolved: ipv6: mcast: fix RCU list diversion in ip6mcdel1src When removing a source filter whose count reaches zero, ip6mcdel1src unlinks psf from pmc-mcasources. If the filter was previously active, the code moved psf directly into...

AZL-104895 CVE-2026-91768 affecting package php 8.3.33-1

The IPv6 branch of the FastCGI client access check compares only the first 12 bytes of a 16-byte IPv6 address, so listen.allowedclients matches on a /96 prefix instead of the exact address. An attacker who can source an address sharing the first 96 bits with an allowed one passes the check and...

CVE-2026-91768

A flaw was found in PHP. The access control check for Internet Protocol version 6 IPv6 addresses in the FastCGI implementation compares only the first 12 bytes of a 16-byte address instead of the complete address. An attacker on an adjacent network with an address sharing the first 96 bits with a...

CVE-2026-100390

Zoraxy versions 3.2.3 through 3.3.4 fail to properly parse IPv6 addresses in the RemoteAddr field when setting forwarded headers. Unauthenticated attackers connecting over IPv6 can supply arbitrary X-Forwarded-For values to spoof their source IP and bypass authorization provider IP-based access...

CVE-2026-91768

The PHP FastCGI client contains an IPv6 access control bypass vulnerability (CVE-2026-91768 ). The issue stems from the IPv6 branch of the FastCGI client access check, which incorrectly compares only the first 12 bytes of a 16-byte IPv6 address. This causes listen.allowed_clients to match on a /9...
