CVE-2026-89255 Details
Description
AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 contains a stored cross-site scripting vulnerability in the LoginControl plugin that fails to HTML-encode PGP public keys echoed into a textarea element. An authenticated attacker can inject malicious JavaScript by submitting a crafted public key, which executes in an administrator's session when viewing the user's profile tab.
A stored cross-site scripting vulnerability has been identified in the AVideo platform, specifically within the LoginControl plugin, prior to commit c3edcc274c389816d434acadac07ee78eaf330c1. The vulnerability arises because PGP public keys are not properly HTML-encoded before being displayed in a textarea element. This flaw allows authenticated attackers to inject malicious JavaScript by submitting a manipulated public key. The injected script executes in the context of an administrator's session when the user's profile tab is viewed.
