| CVE-2026-79668 | MOYENNE5.3 | 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 fav_count field for any known ech | 25/08/2026 |
| CVE-2026-79667 | ÉLEVÉE7.6 | 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, and the backup ex | 25/08/2026 |
| CVE-2026-79666 | MOYENNE6.5 | Ech0 before 4.4.3 fails to enforce administrator authorization on dashboard log endpoints, allowing any authenticated user to access system logs. Attackers with valid user sessions can query GET /api/system/logs and subscribe to SSE and WebSocket log streams to retrieve sensitive operational data including file paths, | 25/08/2026 |
| CVE-2026-79664 | ÉLEVÉE7.4 | Ech0 before 4.7.3 fails to properly revoke access tokens created with never-expire option, allowing attackers to maintain perpetual authenticated access after token theft. Three independent revocation mechanisms fail: logout panics on nil ExpiresAt field, RevokeToken skips when remainTTL is zero, and admin delete does | 25/08/2026 |
| CVE-2026-79663 | MOYENNE4.8 | Ech0 before 4.7.3 contains a stored cross-site scripting vulnerability in the public RSS feed where tag names and markdown content are rendered without HTML escaping.

| CVE-2026-79662 | ÉLEVÉE8.0 | Ech0 through 4.5.6 contains an OAuth redirect URI validation vulnerability in parseAndValidateClientRedirect (internal/service/auth/auth.go) that compares only the scheme and host of the client-supplied redirect_uri against the admin-configured allowlist, ignoring path, query, and fragment components. The redirect_uri | 25/08/2026 |
| CVE-2026-79661 | MOYENNE6.5 | Ech0 through 4.5.6 registers the PUT /api/echo/like/:id endpoint on the public router group without authentication or rate limiting. Unauthenticated attackers can increment the fav_count counter of any echo (including private echoes) by supplying its UUID, which can be harvested from the public GET /api/echo/page feed. | 25/08/2026 |
| CVE-2026-79660 | MOYENNE5.3 | Ech0 versions before 4.7.3 expose guest commenter email addresses through public API endpoints due to improper JSON serialization tags on the Comment model.

| CVE-2026-35037 | ÉLEVÉE7.2 | Ech0 is an open-source, self-hosted publishing platform for personal idea sharing. Prior to 4.2.8, the GET /api/website/title endpoint accepts an arbitrary URL via the website_url query parameter and makes a server-side HTTP request to it without any validation of the target host or IP address. The endpoint requires no | 06/04/2026 |
| CVE-2026-35036 | ÉLEVÉE7.5 | Ech0 is an open-source, self-hosted publishing platform for personal idea sharing. Prior to 4.2.8, Ech0 implements link preview (editor fetches a page title) through GET /api/website/title. That is legitimate product behavior, but the implementation is unsafe: the route is unauthenticated, accepts a fully attacker-cont | 06/04/2026 |
| CVE-2026-33638 | MOYENNE5.3 | Ech0 is an open-source, self-hosted publishing platform for personal idea sharing.
