• CVE-2026-33485: 0.48% estimated exploitation activity in the next 30 days; percentile 41.15 (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 RTMP onpublish callback at plugin/Live/onpublish.php is accessible without authentication. The $POST['name'] parameter (stream key) is interpolated directly into SQL queries in two locations — LiveTransmitionHistory::getLatest() and LiveTransmition::keyExists() — without parameterized binding or escaping. An unauthenticated attacker can exploit time-based blind SQL injection to extract all database contents including user password hashes, email addresses, and other sensitive data. Details Entry point: plugin/Live/onpublish.php — no authentication, no IP allowlist, no origin verification. Sanitization (insufficient): Line 117 strips only & and = characters: Injection point #1 — unconditional (no p parameter needed): At line 120, $POST['name'] is passed directly to LiveTransmitionHistory::getLatest(): Inside getLatest(), the key is interpolated into a LIKE clause without escaping: Injection point #2 — when $GET['p'] is provided: At line 146, $POST['name'] is passed to…

# Patch Next advisory brief: CVE-2026-33485

Advisory: AVideo has an Unauthenticated Blind SQL Injection in RTMP on_publish Callback via Stream Name Parameter
IDs: CVE-2026-33485, GHSA-8p58-35c3-ccxx
Record: https://patchnext.com/advisories/cve-2026-33485 (revision 1, source checked 26 Oct 2026, 14:40 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: High (CVSS 7.5)
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-8p58-35c3-ccxx (GitHub-reviewed advisory GHSA-8p58-35c3-ccxx lists affected ranges: Packagist wwbn/avideo >=0 <=26.0)
