• CVE-2026-33761: 0.40% estimated exploitation activity in the next 30 days; percentile 34.00 (FIRST EPSS, 2026-11-03). This is a model estimate, not proof of exploitation or customer exposure.

As published by the source; long descriptions are shortened.

Summary Three list.json.php endpoints in the Scheduler plugin lack any authentication check, while every other endpoint in the same plugin directories (add.json.php, delete.json.php, index.php) requires User::isAdmin(). An unauthenticated attacker can retrieve all scheduled tasks (including internal callback URLs and parameters), admin-composed email messages, and user-to-email targeting mappings by sending simple GET requests. Details The vulnerable files are: 1. plugin/Scheduler/View/Schedulercommands/list.json.php:1-7 2. plugin/Scheduler/View/Emailsmessages/list.json.php:1-10 3. plugin/Scheduler/View/Emailtouser/list.json.php:1-10 None of these files check authentication before calling getAll(), which executes SELECT FROM {table} and returns the entire table contents. In contrast, every sibling endpoint requires admin access. For example, plugin/Scheduler/View/Schedulercommands/add.json.php:12-15: The Schedulercommands table (defined in…

# Patch Next advisory brief: CVE-2026-33761

Advisory: AVideo: Unauthenticated Access to Scheduler Plugin Endpoints Leaks Scheduled Tasks, Email Content, and User Mappings
IDs: CVE-2026-33761, GHSA-j724-5c6c-68g5
Record: https://patchnext.com/advisories/cve-2026-33761 (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.

## Sources
- Verified: https://github.com/advisories/GHSA-j724-5c6c-68g5 (GitHub-reviewed advisory GHSA-j724-5c6c-68g5 lists affected ranges: Packagist wwbn/avideo >=0 <=26.0)
