What to do

AI-suggested

To mitigate CVE-2025-69771, users and organizations should immediately cease using the asbplayer Chrome Extension version 1.14.0 until an official patch is released. Avoid loading subtitle files from untrusted or unknown sources, especially .srt files received via email, messaging platforms, or third-party websites. Network administrators can implement Content Security Policies (CSP) to restrict script execution contexts and limit the extension's ability to perform unauthorized API calls. Monitoring network traffic for unusual same-site API requests originating from browser extensions can help detect exploitation attempts. Developers of the extension should implement strict input validation and sanitization for subtitle files, ensuring that any embedded scripts or executable content are neutralized before processing. Additionally, adopting a least-privilege approach in extension permissions can reduce the attack surface. Users should keep their browsers and extensions updated and consider using alternative, more secure subtitle handling solutions until this vulnerability is resolved.

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.
