CVE-2026-33496
HighSummary
ORY Oathkeeper, będący proxy tożsamości i API do podejmowania decyzji o dostępie, jest podatny na obejście uwierzytelnienia w wersjach przed 26.2.0 z powodu zamieszania z kluczem pamięci podręcznej. Atakujący może wykorzystać ważny token do wypełnienia pamięci podręcznej, a następnie użyć go w regułach korzystających z innego serwera introspekcji.
Risk Assessment
Organizacja może być narażona na nieautoryzowany dostęp do zasobów, jeśli atakujący zdobędzie ważny token dla jednego z skonfigurowanych serwerów introspekcji. To może prowadzić do poważnych naruszeń bezpieczeństwa danych.
Recommendation
Zaleca się aktualizację Ory Oathkeeper do wersji 26.2.0 lub nowszej, aby zapobiec zamieszaniu z tokenami poprzez uwzględnienie adresu URL serwera introspekcji w kluczu pamięci podręcznej.

Bifrost registers MCP clients through its management API, where a stdio client is a command plus args that is started immediately upon client addition, with no MCP handshake required. Authentication is disabled by default (governance.auth_config.is_enabled=false), meaning every caller is treated as a local admin. A single unauthenticated POST /api/mcp/client is enough to run a program as the Bifrost process user (appuser on the official image).

- CVE-2026-85192Critical
The Joomla Conditional Content extension (regularlabs.com) in versions < 8.0.0 allows authenticated, privileged remote code execution. Conditional Content Pro accepts inline PHP Condition Rules in article syntax, and in affected versions the PHP is passed to the Conditions evaluator without checking who authored the article. Joomla's normal Author text filter preserves the syntax, so publishing the article causes the code to run as the web-server process.

Original NVD description (English source)
ORY Oathkeeper is an Identity & Access Proxy (IAP) and Access Control Decision API that authorizes HTTP requests based on sets of Access Rules. Versions prior to 26.2.0 are vulnerable to authentication bypass due to cache key confusion. The `oauth2_introspection` authenticator cache does not distinguish tokens that were validated with different introspection URLs. An attacker can therefore legitimately use a token to prime the cache, and subsequently use the same token for rules that use a different introspection server. Ory Oathkeeper has to be configured with multiple `oauth2_introspection` authenticator servers, each accepting different tokens. The authenticators also must be configured to use caching. An attacker has to have a way to gain a valid token for one of the configured introspection servers. Starting in version 26.2.0, Ory Oathkeeper includes the introspection server URL in the cache key, preventing confusion of tokens. Update to the patched version of Ory Oathkeeper. If
