BIT-KEYCLOAK-2026-11800 Org.keycloak:keycloak-services: keycloak: authentication bypass via jwt algorithm confusion

A flaw was found in Keycloak. This JWT algorithm confusion vulnerability in the JWT Authorization Grant flow allows an attacker with valid client credentials to bypass signature verification. By forging an assertion, the attacker can create unauthorized access tokens. This enables the attacker to...

CVE-2026-79673 Ech0 before 4.4.3 Scope Bypass via profile:read Token

Ech0 before 4.4.3 protects the PUT /user endpoint with the profile:read scope, a read-only scope, but allows write operations including password changes. An attacker with an admin's profile:read access token can change the admin's password and login to obtain an unrestricted session token that...

CVE-2026-79672 Ech0 before 4.4.3 Authentication Bypass via Comment Panel

Ech0 before 4.4.3 fails to enforce scope-based authorization on nine comment panel admin endpoints, allowing access tokens with minimal scopes to perform full comment moderation operations. Attackers with a limited-scope access token can list, approve, reject, delete comments, and modify comment...

CVE-2026-79668 Ech0 before 4.7.3 Unauthenticated Like Endpoint Metric Inflation

Ech0 before 4.7.3 contains an authentication bypass vulnerability in the PUT /api/echo/like/:id endpoint that allows unauthenticated attackers to increment engagement metrics without identity verification or rate limiting. Attackers can send repeated requests to arbitrarily inflate the favcount...

CVE-2026-79668

Ech0 versions before 4.7.3 contain an authentication bypass in the PUT /api/echo/like/:id endpoint. The endpoint lacks both identity verification and rate limiting, allowing unauthenticated attackers to repeatedly increment the fav_count field for any known echo identifier. This can arbitrarily i...

CVE-2026-79667 Ech0 before 4.4.3 Authentication Bypass via Scope Enforcement

Ech0 version 4.3.4 and earlier fails to reliably enforce scoped access token least-privilege restrictions on several privileged admin routes. Multiple privileged endpoints e.g., /api/inbox, /api/panel/comments, /api/backup/export omit scope checks and authorize based only on the user's admin role...
