Estado: ModificadaMedia (5.4)—

In Requarks wiki.js, versions 2.0.0-beta.147 to 2.5.255 are affected by Stored XSS vulnerability, where a low privileged (editor) user can upload a SVG file that contains malicious JavaScript while uploading assets in the page. That will send the JWT tokens to the attacker’s server and will lead to account takeover when accessed by the victim.

CVSS
