CVE-2024-45621

Name of the Vulnerable Software and Affected Versions: Rocket.Chat versions through 6.3.4

Description: The Electron desktop application of Rocket.Chat allows stored XSS via links in an uploaded file, related to failure to use a separate browser upon encountering third-party external actions from PDF documents. This issue can compromise user sessions.

Recommendations: For versions through 6.3.4, update to a version later than 6.3.4 to resolve the issue. As a temporary workaround, consider restricting the upload of files that may contain links to mitigate the risk of exploitation.
