• CVE-2026-33723: 0.23% estimated exploitation activity in the next 30 days; percentile 13.60 (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 The Subscribe::save() method in objects/subscribe.php concatenates the $this-usersid property directly into an INSERT SQL query without sanitization or parameterized binding. This property originates from $POST['userid'] in both subscribe.json.php and subscribeNotify.json.php. An authenticated attacker can inject arbitrary SQL to extract sensitive data from any database table, including password hashes, API keys, and encryption salts. Details The vulnerability exists because of a disconnect between where intval() is applied and where the value is used in SQL. Entry points — objects/subscribe.json.php:40 and objects/subscribeNotify.json.php:23: Constructor stores raw value — objects/subscribe.php:34: getSubscribeFromID sanitizes local copies only — objects/subscribe.php:137-139: When getSubscribeFromID finds no matching subscription (the attacker simply targets a userid they haven't subscribed to), loadFromId() returns false. The object's $this-id remains null, and…

# Patch Next advisory brief: CVE-2026-33723

Advisory: AVideo is Vulnerable to SQL Injection through Subscribe Endpoint via Unsanitized user_id Parameter
IDs: CVE-2026-33723, GHSA-ffr8-fxhv-fv8h
Record: https://patchnext.com/advisories/cve-2026-33723 (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: High (CVSS 7.1)
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-ffr8-fxhv-fv8h (GitHub-reviewed advisory GHSA-ffr8-fxhv-fv8h lists affected ranges: Packagist wwbn/avideo >=0 <=26.0)
