Description
Cross-Site Scripting (XSS) vulnerability in the subtitle loading function of the asbplayer Chrome Extension version 1.14.0 allows attackers to execute arbitrary JavaScript in the context of the active streaming platform via a crafted .srt subtitle file. Because the script executes within the same-site context, it can bypass cross-origin restrictions, leading to unauthorized same-site API requests and session data exfiltration.
