What is CVE-2024-10054?

The Happyforms plugin for WordPress, prior to version 1.26.3, is susceptible to Stored Cross-Site Scripting (XSS) vulnerabilities due to improper sanitization and escaping of critical settings. This flaw allows users with high privileges, such as administrators, to inject malicious scripts, even in environments where the unfiltered_html capability is normally restricted, like in multisite installations. As a result, attackers may exploit this vulnerability to execute unauthorized scripts, potentially compromising website security.

Affected Version(s)

Happyforms 1.26.2 < 1.26.3

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.
