What is CVE-2024-3586?

The LetterPress WordPress plugin, prior to version 2.4.0, has a significant vulnerability where certain settings are not properly sanitized and escaped. This loophole can potentially allow users with higher privileges, such as administrators, to execute Stored Cross-Site Scripting (XSS) attacks. This is particularly concerning in multisite environments where the unfiltered_html capability is disallowed, enabling attackers to exploit this flaw even in secure configurations.

Affected Version(s)

LetterPress 0 < 2.4.0

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.
