Deserialization of Untrusted Data
CVE CVE-2025-24671
CVSS 8.1 (High)
Publicly Published January 21, 2025
Last Updated February 24, 2025
Researcher LVT-tholv2k

Description

The Save as PDF Plugin by Pdfcrowd plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 4.4.0 via deserialization of untrusted input. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software, which means this vulnerability has no impact unless another plugin or theme containing a POP chain is installed on the site. If a POP chain is present via an additional plugin or theme installed on the target system, it may allow the attacker to perform actions like delete arbitrary files, retrieve sensitive data, or execute code depending on the POP chain present.
