MEDIUM 5.1EPSS 0.32%

Does this matter?

Lower severity and a low EPSS score (0.32%). Track it; it rarely justifies an emergency change on its own.

Description

Stored Cross-Site Scripting (XSS) vulnerability in Sesame web application, due to the fact that uploaded SVG images are not properly sanitized. This allows attackers to embed malicious scripts in SVG files by sending a POST request using the 'logo' parameter in '/api/v3/companies/<ID>/logo', which are then stored on the server and executed in the context of any user who accesses the compromised resource.
