Deeper analysis
The Ultimate Member plugin for WordPress, which handles user profiles, registration, login, member directories, content restriction, and membership features, is affected by CVE-2025-0308. This time-based SQL injection vulnerability exists in all versions through 2.9.1 and stems from insufficient escaping of the user-supplied search parameter combined with inadequate preparation of the existing SQL query in the member directory component.
Unauthenticated attackers can exploit the flaw over the network by supplying crafted input to the search parameter, allowing them to append additional SQL queries and extract sensitive information from the database. The issue carries a CVSS 3.1 score of 7.5, reflecting high confidentiality impact with no authentication or user interaction required.
Advisories referenced in the Wordfence threat intelligence entry and the plugin source trace highlight the vulnerable code path but do not detail specific patch versions or mitigation steps beyond the general need to update the plugin.
EPSS for the CVE rose from a low baseline to a peak of 0.0186 on 2026-02-25 before receding to the current value of 0.0064, indicating a period of increased exploitation interest after initial disclosure.
