QID 982747: Python (pip) Security Update for matrix-sydent (GHSA-9jhm-8m8c-c3f4)

Security update has been released for matrix-sydent to fix the vulnerability.

Note: The preceding description block is extracted directly from the security advisory. Using automation, we have attempted to clean and format it as much as possible without introducing additional issues.

Sydent can be induced to send HTTP GET requests to internal systems, due to lack of parameter validation or IP address blacklisting.

It is not possible to exfiltrate data or control request headers, but it might be possible to use the attack to perform an internal port enumeration.

CVSS V3 rated as High - 6.5 severity.

CVSS V2 rated as Medium - 4 severity.

Solution

Fixed in 9e57334, 8936925, 3d531ed, 0f00412Workaround:
A potential workaround would be to use a firewall to ensure that Sydent cannot reach internal HTTP resources.
