Detailsinfo

A vulnerability classified as problematic has been found in franklioxygen MyTube up to 1.10.5. Affected is the function shouldSkipCsrfProtection of the file backend/src/middleware/csrfConfig.ts of the component CSRF Protection. The manipulation with an unknown input leads to a cross-site request forgery vulnerability. CWE is classifying the issue as CWE-352. The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request. This is going to have an impact on integrity. CVE summarizes:

MyTube is a self-hosted downloader and player for several video websites. Prior to 1.10.6, shouldSkipCsrfProtection() in backend/src/middleware/csrfConfig.ts delegates to isApiKeyRequest(), which grants a CSRF exemption based only on the presence of an x-api-key header or an Authorization: ApiKey value rather than successful API-key validation. With a permissive CORS_ALLOWED_ORIGINS configuration, an unauthenticated attacker can lure an authenticated administrator to attacker-controlled content that sends a cross-origin state-changing request with an arbitrary API-key value. The victim's session cookie authenticates the request while CSRF token validation is skipped, allowing destructive or other administrator API operations such as deleting media, triggering downloads, or changing subscriptions. This issue is fixed in version 1.10.6.

The advisory is shared for download at github.com. This vulnerability is traded as CVE-2026-63433 since 07/16/2026. The exploitability is told to be easy.
