What is known
The Security & Malware scan by CleanTalk WordPress plugin before 2.121 retrieves client IP addresses from potentially untrusted headers, allowing an attacker to manipulate its value. This may be used to bypass bruteforce protection.
Business impact
Successful exploitation of CVE-2023-5239, a high vulnerability (CVSS 7.5) affecting security \& malware scan, may affect the confidentiality, integrity or availability of the vulnerable environment. The exact impact depends on the installed version, exposed interfaces and deployment configuration.
Recommended administrator action
Confirm whether security \& malware scan is present and compare installed versions with the vendor advisory and NVD record. Apply the vendor patch or documented mitigation; until remediation is complete, reduce exposure of affected interfaces, review relevant logs and monitor for indicators of exploitation.
