CVE-2024-50344

Supplemental Files are allowed to be viewed in the browser, only if they have a white-listed MIME type.

MEDIUM 4.6EPSS 0.30%

Does this matter?

Lower severity and a low EPSS score (0.30%). Track it; it rarely justifies an emergency change on its own.

Description

I, Librarian is an open-source version of a PDF managing SaaS. Supplemental Files are allowed to be viewed in the browser, only if they have a white-listed MIME type. Unfortunately, this logic is broken, thus allowing unsafe files containing Javascript to be executed with the application context. An attacker can exploit this vulnerability by uploading a supplementary file that contains a malicious code or script. This code will then be executed when the file is loaded in the browser. The vulnerability was fixed in version 5.11.2.
