Descripción
*** Pendiente de traducción *** Penpot is an open-source design and prototyping platform. In versions up to and including 2.14.3, Penpot is vulnerable to stored cross-site scripting through custom font family names, which are interpolated into a @font-face CSS rule and injected into the page as HTML without sanitization. Because the backend accepts an arbitrary font-family string and the frontend writes the resulting style through innerHTML, a name containing markup such as a closing style tag followed by a script can break out of the style element and execute JavaScript on the Penpot origin. The attack is passive: any team member who opens a file referencing the malicious font triggers script execution simply by rendering the page, allowing theft of session cookies, actions performed as the victim, and access to their files and projects. This issue is fixed in version 2.15.3.
