Name of the Vulnerable Software and Affected Versions String Locator plugin for WordPress versions up to, and including 2.5.0

Description The issue allows deserialization of untrusted input via the string-locator-path parameter. This enables unauthenticated users to call files using a PHAR wrapper if they can trick a site administrator into performing a specific action, such as clicking on a link, which deserializes and calls arbitrary PHP Objects. This can lead to various malicious actions if a POP chain is also present, and the attacker successfully uploads a file with the serialized payload.

Recommendations For String Locator plugin for WordPress versions up to, and including 2.5.0, update to a version higher than 2.5.0 to resolve the issue. As a temporary workaround, consider restricting access to the string-locator-path parameter to minimize the risk of exploitation. Avoid using the string-locator-path parameter in the affected plugin until the issue is resolved.
