CVE-2026-28501: WWBN AVideo: Unauthenticated SQL Injection via JSON Request Bypass in objects/videos.json.php
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
This vulnerability is classified as: - CWE-89: Improper Neutralization of Special Elements used in an SQL Command (SQL Injection)
Patches
This vulnerability has been fixed in version 23.
Users must upgrade to version 23 or later.
Workarounds
There is no reliable workaround.
The only recommended mitigation is to upgrade immediately to version 23 upon its release.
