2DescriptionCVE.org
The Ultimate Member - User Profile, Registration, Login, Member Directory, Content Restriction & Membership Plugin plugin for WordPress is vulnerable to blind SQL Injection via the search parameter in all versions up to, and including, 2.10.1 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database. This vulnerability was partially patched in version 2.9.2 when initially addressing CVE-2025-0308.
AnalysisAI
Blind SQL injection in the Ultimate Member WordPress plugin (all versions through 2.10.1) lets unauthenticated attackers inject arbitrary SQL through the member-directory search parameter, enabling extraction of sensitive database contents such as password hashes and user records. The flaw is a residual gap from the earlier CVE-2025-0308 fix, which was only partially remediated in 2.9.2. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires that the target site runs Ultimate Member ≤ 2.10.1 with the member-directory feature exposed and reachable so that the vulnerable 'search' parameter can be reached over the network. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N, base 7.5) reflects a network-reachable, low-complexity, unauthenticated flaw with high confidentiality impact but no integrity or availability impact - consistent with a read-only data-exfiltration SQLi. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker locates a WordPress site running Ultimate Member with a public member directory and submits crafted values in the directory 'search' parameter, appending boolean/time-based SQL to the existing query. By observing differential responses or timing, they iteratively extract usernames, email addresses, and password hashes from the wp_users table without any login. … |
| Remediation | Upstream fix available (PR/commit); released patched version not independently confirmed - the input references code changesets https://plugins.trac.wordpress.org/changeset/3222364/ultimate-member/trunk/includes/core/class-member-directory.php and https://plugins.trac.wordpress.org/changeset/3265901/ rather than a named release, so upgrade to the latest available Ultimate Member version above 2.10.1 and verify the fix against the vendor advisory (https://www.wordfence.com/threat-intel/vulnerabilities/id/8f539e25-5483-417d-a3c5-e7034c03c673?source=cve) before relying on a specific version number. … Detailed patch versions, workarounds, and compensating controls in full report. |
