Summary The objects/playlistsVideos.json.php endpoint returns the full video contents of any playlist by ID without any authentication or authorization check. Private playlists (including watchlater and favorite types) are correctly hidden from listing endpoints via playlistsFromUser.json.php, but their contents are directly accessible through this endpoint by providing the sequential integer playlistsid parameter. Details The endpoint at objects/playlistsVideos.json.php accepts a playlistsid parameter and directly calls PlayList::getVideosFromPlaylist() with no ownership or visibility validation: The getVideosFromPlaylist() method at objects/playlist.php:588 performs a SQL query joining playlistshasvideos, videos, and users tables with no authorization filter: In contrast, the listing endpoint playlistsFromUser.json.php correctly enforces visibility at lines 23-27: This creates a bypass: even though private playlists are hidden from listing, their contents are fully exposed via the…

# Patch Next advisory brief: CVE-2026-33759

Advisory: AVideo: Unauthenticated IDOR in playlistsVideos.json.php Exposes Private Playlist Contents
IDs: CVE-2026-33759, GHSA-75qq-68m8-pvfr
Record: https://patchnext.com/advisories/cve-2026-33759 (revision 1, source checked 26 Oct 2026, 14:39 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 5.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor response not established. A vendor fix does not mean a deployment is fixed.

## Affected components
- Packagist wwbn/avideo: affected <= 26.0

## Suggested inspection (read-only)
- Packagist wwbn/avideo: check the installed version with your package manager.

## Supported action
No complete vendor fix is recorded. Follow the primary source's mitigation guidance and check this record again before closing anything.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on wwbn/avideo.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
