What is CVE-2026-19093?

The Tutor LMS WordPress plugin, prior to version 4.0.6, has a significant security issue due to the lack of validation for stored file paths when streaming media. This oversight allows users with instructor permissions to read arbitrary files stored on the server. As a result, sensitive information, such as the WordPress configuration file, can be accessed, leading to exposure of database credentials and authentication keys. Such vulnerabilities could enable attackers to forge authentication cookies, posing a serious risk to the integrity of the affected WordPress site.

Affected Version(s)

Tutor LMS 0 < 4.0.6

Exploit Proof of Concept (PoC)

PoC code is written by security researchers to demonstrate the vulnerability can be exploited. PoC code is also a key component for weaponization which could lead to ransomware.
