Information Disclosure via X-Jitsi-Release Header

Description

The 'X-Jitsi-Release' header indicates which version or release of the Jitsi platform (e.g., Jitsi Meet) is in use. Disclosing this information can help attackers pinpoint known vulnerabilities, exploit default configurations, or craft targeted attacks against the specific release of Jitsi. Additionally, learning the Jitsi version aids malicious actors in social engineering by referencing potential weaknesses or known bugs. Ultimately, revealing this header undermines the principle of security by obscurity and increases the risk that attackers will successfully exploit version-specific issues within Jitsi services.

Remediation

Remove or mask the 'X-Jitsi-Release' header so as not to disclose your Jitsi version to unauthorized parties. Configure your Jitsi deployment or proxy settings to omit identifying headers. Keep all Jitsi components, plugins, and related services updated with the latest patches. If you use reverse proxies or load balancers, ensure they strip or rewrite this header before responses reach external clients. Additionally, consider employing a Web Application Firewall (WAF) or intrusion detection system to identify and block attempts targeting Jitsi-related vulnerabilities. Regular audits of response headers help ensure that no internal version details are inadvertently exposed.
