rabbitmq-server: rabbitmq-server: Authentication bypass via improper validation of floating-point token expiration timestamps

A flaw was found in rabbitmq-server. When configured to use OAuth 2.0 authentication, the server does not properly validate token expiration timestamps that are represented as floating-point numbers. A remote attacker with an expired token can exploit this issue to bypass expiration checks, gaini...

rabbitmq-server: rabbitmq-server: Unauthorized user impersonation via stale OAuth token refresh

A flaw was found in rabbitmq-server. When an existing Advanced Message Queuing Protocol AMQP connection refreshes its authentication token to one with revoked impersonation privileges, the server fails to update the active session's security tags. As a result, an authenticated user can retain...

CVE-2026-57134

PraisonAI (npm package praisonai) is a multi-agent teams system. The MCPSecurity.evaluatePolicy() function in src/praisonai-ts/src/mcp/security.ts only invokes the configured credential validator when the AuthMethod is api-key or bearer. For basic and oauth policies, any non-empty Authorization h...

CVE-2026-57134 PraisonAI MCPSecurity Basic/OAuth authentication policies accept invalid credentials without validation

PraisonAI is a multi-agent teams system. From 1.5.1 until 1.7.2, MCPSecurity.evaluatePolicy in src/praisonai-ts/src/mcp/security.ts invokes the configured credential validator only when AuthMethod is api-key or bearer. Basic and OAuth policies accept any non-empty Authorization header without...

CVE-2026-44203

Open Access Management OpenAM is an access management solution. Prior to 16.1.1, the OAuth 2.0 and OpenID Connect authorization endpoint does not sufficiently encode user-supplied parameters before FormPostResponse.ftl and checkSession.ftl render them into HTML for the formpost response mode. An...

grafana: Grafana: Denial of Service via unbounded memory growth in OAuth login route

A flaw was found in Grafana. An unauthenticated attacker can repeatedly access the OAuth login route with unique values. This can lead to unbounded memory growth, eventually exhausting system memory and causing the Grafana instance to crash. This results in a denial of service for legitimate user...
