Authentication bypass by spoofing vulnerability in Apache APISIX. On a route where multi-auth falls back from wolf-rbac to another successful authenticator, client-supplied Wolf identity headers can remain in the request. A downstream service that relies on those documented headers may therefore receive an identity that was not established by the successful authenticator. This issue affects Apache APISIX: from 3.8.0 through 3.19.0. Users are recommended to upgrade to version 3.20.0, which fixes the issue.

CVE-2026-124719——
———Authentication bypass by spoofing vulnerability in Apache APISIX.
When a Route's configured headers carry a caller identity and the OpenAPI document declares
the same header, a caller can act as another identity against the
upstream API. This issue affects Apache APISIX: from 3.19.0 before 3.20.0.
Users are recommended to upgrade to version 3.20.0, which fixes the issue.2hCVE-2026-124679——
———Authentication bypass by spoofing vulnerability in Apache APISIX.
On routes using jwe-decrypt with strict: false and a
forward_header distinct from the token header an unauthenticated
client can supply the value the upstream treats as gateway-decrypted
plaintext. Similar can happen when forward-auth is configured with allow_degradation: true, and the auth service is unavailable.
This issue affects Apache APISIX: from 3.18.0 through 3.19.0.
Users are recommended to upgrade to version 3.20.0, which fixes the issue.2hCVE-2026-1280237.4 ALT—
——0FrankenPHP before 1.13.0 contains an authentication bypass vulnerability that allows unauthenticated attackers to spoof trusted headers by sending dot-form header names that PHP rewrites to underscores. Attackers can send headers like X.Authenticated.User or X.Forwarded.For that map to $_SERVER keys, spoofing user identity, client IP, or scheme.15hCVE-2026-121619——
——0The Symfony FrameworkBundle framework.trusted_proxies option and the HttpFoundation Request::setTrustedProxies() method trust remote clients as reverse proxies when the private_ranges shortcut is used, allowing remote attackers to spoof the client IP address, host and scheme in Symfony FrameworkBundle versions 7.1 prior to 7.4.23 and 8.x prior to 8.1.11, and HttpFoundation versions 7.2 prior to 7.4.23 and 8.x prior to 8.1.11. The private_ranges and PRIVATE_SUBNETS keywords resolved to IpUtils::PRIVATE_SUBNETS, the deny list of NoPrivateNetworkHttpClient, which lists the private and special-purpose prefixes a server must not connect to. Since the fix for CVE-2026-48736 (7.4.13 and 8.0.13), this list also covers the IPv6 prefixes that embed an IPv4 address: IPv4-mapped (::ffff:0:0/96), IPv4-compatible (::/96), 6to4 (2002::/16), Teredo (2001::/32) and NAT64 (64:ff9b::/96). The IPv4-mapped entry has been in the list since the private_ranges shortcut was introduced, in 7.1 for framework.trusted_proxies and in 7.2 for Request::setTrustedProxies(). Over-blocking is safe for a deny list, but when the same entries are used as the allow list of trusted proxies, they trust remote clients. A client whose connection arrives with such a source address is treated as a reverse proxy, and the X-Forwarded-For, X-Forwarded-Host, X-Forwarded-Proto, X-Forwarded-Port and X-Forwarded-Prefix headers it sends are honoured. For example, with Request::setTrustedProxies(['private_ranges'], ...), a request with REMOTE_ADDR set to ::ffff:203.0.113.7 and the headers X-Forwarded-For: 10.0.0.9, X-Forwarded-Host: evil.example.com and X-Forwarded-Proto: https makes getClientIp() return 10.0.0.9, getHost() return evil.example.com and isSecure() return true. Two kinds of deployments are exposed: a server listening on the IPv6 wildcard address without IPV6_V6ONLY reports every IPv4 client in the IPv4-mapped form, so every client is trusted, and a server reachable over IPv6 trusts any client sourcing from 6to4 or Teredo space, which is globally routed, whatever its listener. A spoofed client address defeats IP allow lists, rate limiting and audit logs; a spoofed host poisons the URLs written into password reset and login link e-mails and into shared caches; a spoofed scheme satisfies requires_channel: https over plain HTTP. Symfony 6.4 does not point any trusted proxy setting at IpUtils::PRIVATE_SUBNETS and is not affected by default, but an application that passes that constant to Request::setTrustedProxies() itself could be exposed in the same way on any version. This issue is fixed in 7.4.23 and 8.1.11.1dCVE-2026-1190395.3 MÉD3.1%
——1The Defender Security WordPress plugin before 6.4.1 does not verify that the client IP address it derives for its firewall and lockout decisions actually originates from a trusted source, trusting a user-supplied value by default, allowing unauthenticated attackers to spoof their IP address and evade IP-based protections such as login lockout and IP banning, impersonate an allowlisted address, and poison the Defender Security WordPress plugin before 6.4.1's activity logs.1dCVE-2026-1262147.2 ALT35.8%
