CVE-2026-28501: AVideo has Unauthenticated SQL Injection via JSON Request Bypass in objects/videos.json.php

Should you act?

Critical and remotely reachable

No known exploitation yet, but it is network-reachable without credentials. This signal is computed from CISA KEV, EPSS and CVSS data; it is not an editorial verdict.

• No confirmed exploitation. It is not in CISA’s KEV catalog and CISA’s SSVC assessment records no known exploitation. That can change quickly after a public write-up; re-check if you are affected.
• EPSS 1.4%, percentile 73: FIRST’s model estimates a 1.4% chance of exploitation activity in the next 30 days, higher than 73% of all scored CVEs (moderate). EPSS is a probability, not a verdict.
• Remotely reachable with no login and no user interaction. If the vulnerable service is exposed to the internet, prioritize it.
• Only applies if your dependency tree includes wwbn/avideo (Composer (PHP)) <= 21.0.0, no fixed version listed. Check your lockfile, including transitive dependencies.

What it is

WWBN AVideo is an open source video platform. Prior to version 24.0, an unauthenticated SQL Injection vulnerability exists in AVideo within the objects/videos.json.php and objects/video.php components. The application fails to properly sanitize the catName parameter when it is supplied via a JSON-formatted POST request body. Because JSON input is parsed and merged into $REQUEST after global security checks are executed, the payload bypasses the existing sanitization mechanisms. This issue has been patched in version 24.0.

From the GitHub advisory

Impact

An unauthenticated SQL Injection vulnerability exists in AVideo within the objects/videos.json.php and objects/video.php components.

The application fails to properly sanitize the catName parameter when it is supplied via a JSON-formatted POST request body. Because JSON input is parsed and merged into $REQUEST after global security checks are executed, the payload bypasses the existing sanitization mechanisms.

This allows an unauthenticated attacker to:

- Execute arbitrary SQL queries - Perform full database exfiltration - Extract sensitive data including administrator usernames, password hashes, session identifiers and user records - Potentially escalate privileges by cracking password hashes offline - Chain with authenticated vulnerabilities to achieve full system compromise

Weakness type: CWE-89.
