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.

Affected WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • instawp String locator — Up to and including 2.6.6
  • instawp string_locator — Before 2.6.7
