6DescriptionGitHub Advisory
MyTube is a self-hosted downloader and player for several video websites Prior to version 1.8.69, an authorization bypass in the /api/settings/import-database endpoint allows attackers with low-privilege credentials to upload and replace the application's SQLite database entirely, leading to a full compromise of the application. The bypass is relevant for other POST routes as well. Version 1.8.69 fixes the issue.
AnalysisAI
MyTube versions prior to 1.8.69 suffer from an authorization bypass in the /api/settings/import-database endpoint that allows low-privilege authenticated users to upload and replace the application's SQLite database entirely, resulting in complete application compromise. The vulnerability affects self-hosted instances of MyTube and extends to other POST routes using the same flawed authorization mechanism. …

Vulnerability AssessmentAI
| Exploitation | MyTube versions prior to 1.8.69. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | This vulnerability presents significant real-world risk despite the absence of a CVSS score. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker with valid low-privilege credentials (e.g., obtained through credential reuse, phishing, or a compromised account) authenticates to the MyTube instance and crafts a POST request to `/api/settings/import-database` with a malicious SQLite database file. Due to insufficient authorization checks in the middleware, the request succeeds and replaces the legitimate database. … |
| Remediation | Upgrade MyTube to version 1.8.69 or later, which includes the authorization bypass fix per the upstream commit at https://github.com/franklioxygen/MyTube/commit/b7bf9b7960958c6c51f85fe50a2fc041a086c466. … Detailed patch versions, workarounds, and compensating controls in full report. |
