Published: Tue Apr 21 2026 (04/21/2026, 22:49:40 UTC)
Source: CVE Database V5
Vendor/Project: WWBN
Product: AVideo

Description

CVE-2026-41061 is a stored cross-site scripting (XSS) vulnerability in WWBN AVideo versions 29. 0 and below. The issue arises from an improper regex validation in the isValidDuration() function, which allows arbitrary HTML/JavaScript to be appended to a valid duration string. This crafted input is stored in the database and later rendered without proper HTML escaping on various pages, including trending, playlist, and video gallery thumbnails. A fix for this vulnerability is included in commit bcba324644df8b4ed1f891462455f1cd26822a45.

Technical Analysis

WWBN AVideo versions 29.0 and earlier contain a stored XSS vulnerability due to improper input validation in the isValidDuration() regex at objects/video.php:918. The regex lacks an end anchor, allowing attackers to append malicious HTML/JavaScript after a valid duration prefix. This crafted duration value is stored in the database and output without HTML escaping via echo Video::getCleanDuration() on multiple user-facing pages, enabling stored cross-site scripting attacks. The vulnerability is tracked as CWE-79 and has a CVSS 3.1 base score of 5.4 (medium severity). A code commit (bcba324644df8b4ed1f891462455f1cd26822a45) contains the fix.

Potential Impact

Successful exploitation allows an attacker with low privileges and user interaction to inject and execute arbitrary JavaScript in the context of affected WWBN AVideo web pages. This can lead to partial confidentiality and integrity loss of user data as indicated by the CVSS vector (C:L/I:L). There is no impact on availability. The vulnerability affects stored data, making it persistent across sessions and visible to other users viewing the affected pages.

Mitigation Recommendations

A fix is available as indicated by the referenced commit bcba324644df8b4ed1f891462455f1cd26822a45. Users of WWBN AVideo version 29.0 and below should upgrade to a version that includes this fix. Since this is not a cloud service, remediation requires applying the patch or updating the software. Patch status is not explicitly confirmed in the advisory, so users should verify the fix in the vendor's repository or official releases.
