CVE-2016-20082Public exploit

Local code execution via unvalidated action file inclusion

Published Jun 15, 2026 · Updated Jun 15, 2026

Local file inclusion in Lasse Bunk A/B Test for WordPress 1.0.6 allows local users to execute PHP code via the action parameter. abtest_admin.php concatenates the unvalidated GET value after admin/ and appends .php before passing the resulting path to include. A local unauthenticated request can traverse out of that directory and include a server-local PHP file; code execution requires a suitable local file.
