This nine-file repository is an authorized validation lab and functional Python proof of concept for CVE-2026-62059 in the WordPress Ultimate Member plugin. The primary exploit, poc/poc_cve_2026_62059.py, logs in as a WordPress administrator, retrieves edit nonces for a member-directory post, and saves a malicious value in _um_search_include_fields. In affected versions, the unregistered directory metadata key is stored without sanitization and later concatenated into the SQL meta_key IN(...) clause during a member-directory AJAX search. The PoC uses paired 1=1 and 1=2 payloads and a seeded usermeta marker to verify exploitation through a total_users count differential. It is operational but limited to a non-destructive boolean oracle. The Bash lab driver provisions fresh Dockerized WordPress/MySQL environments for Ultimate Member 2.13.1 and patched 2.14.0, verifies both the vulnerable and negative-control paths, and binds the web service only to localhost. A separate Nuclei YAML file performs only a one-request version screen of the publicly accessible plugin readme.txt; it cannot perform the administrator save-and-trigger chain. Repository code includes Python, Bash, and YAML, with Docker Compose configuration and GitHub Actions validation.
