CVE-2022-2438: Managewp Broken Link Checker

High severity, CVSS 7.2. EPSS: 1.8% chance of exploitation in the next 30 days.

The Broken Link Checker plugin for WordPress is vulnerable to deserialization of untrusted input via the '$log_file' value in versions up to, and including 1.11.16. This makes it possible for authenticated attackers with administrative privileges and above to call files using a PHAR wrapper that will deserialize the data and call arbitrary PHP Objects that can be used to perform a variety of malicious actions granted a POP chain is also present. It also requires that the attacker is successful in uploading a file with the serialized payload.

Affected products

• Managewp Broken Link Checker: before 1.11.17 (fixed in 1.11.17)
