CVE-2026-45580: CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') in WWBN AVideo
WWBN AVideo is an open source video platform. In 29.0 and earlier, there is a stored cross-site scripting vulnerability. The Live plugin's "YouTube-style" view renders the live transmission's stream key into an HTML class attribute by raw echo, without htmlspecialchars(). A canStream user can persist a key containing " plus an event handler via plugin/Live/saveLive.php, and any visitor (logged in or anonymous) opening the stream's live page executes attacker JavaScript in the platform origin.
AI Analysis
Technical Summary
CVE-2026-45580 is a stored cross-site scripting vulnerability in WWBN AVideo (<= 29.0) affecting the Live plugin. The vulnerability occurs because the stream key is output directly into an HTML class attribute without htmlspecialchars() encoding, enabling a user with canStream privileges to inject JavaScript payloads via the plugin/Live/saveLive.php endpoint. When other users visit the live stream page, the injected script executes in their browsers under the platform's origin, potentially leading to information disclosure or session hijacking. The CVSS v3.1 score is 5.4 (medium severity), reflecting low complexity and limited privileges required but requiring user interaction.
Potential Impact
An attacker with canStream privileges can inject persistent malicious JavaScript into the live stream page, which executes in the browsers of any visitors (authenticated or anonymous). This can lead to limited confidentiality and integrity impacts such as theft of user data or session tokens. Availability is not affected. The vulnerability requires user interaction (visiting the live stream page) and privileges to submit the malicious stream key.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict canStream privileges to trusted users only and consider disabling the Live plugin or avoiding use of the live stream feature. Monitor vendor channels for updates and apply official patches once released.
