Description

The Social Media Share Buttons plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 2.1.0 via deserialization of untrusted input through the attachmentUrl parameter. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable plugin. 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. CVE-2024-2721 is likely a duplicate to this issue.
