Detection Guidance

CVE-2026-27082 is a PHP Object Injection vulnerability affecting the WordPress Love Story Theme versions up to 1.3.12. Detection typically involves monitoring for attack patterns targeting this specific flaw.

Patchstack has issued a mitigation rule to block attacks targeting this vulnerability, which can be used as part of detection and prevention.

While no specific commands are provided in the available resources, general detection methods include:

• Monitoring web server logs for suspicious POST or GET requests containing serialized PHP objects or unusual payloads targeting the Love Story theme.
• Using web application firewalls (WAF) with rules from Patchstack or similar providers to detect and block exploitation attempts.
• Scanning the website files to verify the version of the Love Story theme and confirming if it is version 1.3.12 or lower, which is vulnerable.

For command-line checks, you might consider commands such as:

• grep -r 'lovestory' /path/to/wordpress/wp-content/themes/ to locate the theme directory and check version files.
• curl or wget commands to simulate requests with serialized PHP objects to test if the site responds abnormally (only in a controlled environment).

It is strongly recommended to apply Patchstack's mitigation rules or update the theme to a non-vulnerable version as soon as possible.
