CVE-2024-1813: Simple Job Board <= 2.11.0 - Unauthenticated PHP Object Injection via Job Application Fields
The Simple Job Board plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.11.0 via deserialization of untrusted input in the jobboardapplicantlistcolumnsvalue function. This makes it possible for unauthenticated attackers to inject a PHP Object. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code when a submitted job application is viewed.
