CVE-2026-24139: MyTube Allows Unauthorized Database Export by Guest Users

MyTube is a self-hosted downloader and player for several video websites. Versions 1.7.78 and below do not safeguard against authorization bypass, allowing guest users to download the complete application database. The application fails to properly validate user permissions on the database export endpoint, enabling low-privileged users to access sensitive data they should not have permission to view.

Security readout for executives and security teams

Plain-English summary

CVE-2026-24139 affects MyTube, a self-hosted video downloader/player. In versions before 1.7.79, a guest or low-privileged user can download the full application database because the database export function does not properly enforce permissions. This can expose sensitive application data and may affect confidentiality, integrity, and availability of stored data.

Executive priority

Treat as a high-priority remediation for exposed MyTube instances. The issue can allow full database disclosure to low-privileged users, creating potential privacy, credential, or operational impact. Prioritize internet-facing and shared-user deployments first.

Technical view

The issue is an authorization bypass in MyTube’s database export endpoint, classified as CWE-862. A network-accessible, low-privileged user can access a complete database export without user interaction. The CVSS 4.0 score is 8.7. Affected versions are below 1.7.79; the referenced commit and GitHub advisory are the primary public sources.

Likely exposure

Exposure is most relevant for internet-accessible or shared MyTube instances where guest access or low-privileged accounts are enabled. Self-hosted deployments on private networks still have insider or compromised-account risk.

Exploitation context

The CVE record reports low attack complexity, network access, low privileges, and no user interaction. The provided sources do not show active exploitation, and the CVE is not marked as CISA KEV.

Researcher notes

Evidence is limited to the CVE data, GitHub advisory, and fix commit. The public bundle identifies the vulnerable authorization check but does not provide evidence of exploitation in the wild. Avoid assuming broader product impact beyond franklioxygen MyTube versions below 1.7.79.

Mitigation direction

  • Upgrade MyTube to version 1.7.79 or later, based on the affected version range.
  • Review the GitHub advisory and vendor commit for authoritative remediation details.
  • Restrict access to MyTube until upgraded, especially guest or low-privileged access.
  • Limit network exposure for self-hosted instances where business needs allow.
  • Review database contents for sensitive data that may require follow-up handling.

Validation and detection

  • Inventory all MyTube deployments and record running versions.
  • Confirm no instance is running MyTube below 1.7.79.
  • Review application logs for unexpected database export activity by guest or low-privileged users.
  • Verify guest users cannot access database export functionality after remediation.
  • Track the CVE and advisory for any updated vendor guidance.

Missing Authorization

Missing Authorization represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
