What is CVE-2024-10936?
CVE-2024-10936 is a high-severity unsafe deserialization vulnerability in instawp String locator, published on 21 Jan 2025. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.
Official description
The String locator plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.6.6 via deserialization of untrusted input in the 'recursive_unserialize_replace' function. This makes it possible for unauthenticated attackers to inject a PHP Object. No known POP chain is present in the vulnerable software. 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. An administrator must perform a search and replace action to trigger the exploit.
