CVE-2024-51492 Information

Description

Zusam is a free and open-source way to self-host private forums. Prior to version 0.5.6 specially crafted SVG files uploaded to the service as images allow for unrestricted script execution on (raw) image load. With certain payloads theft of the target user’s long-lived session token is possible. Note that Zusam at the time of writing uses a user’s static API key as a long-lived session token and these terms can be used interchangeably on the platform. This session token/API key remains valid indefinitely so long as the user doesn’t expressly request a new one via their Settings page. Version 0.5.6 fixes the cross-site scripting vulnerability.
