Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

The WP-Members Membership Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the X-Forwarded-For header in all versions up to, and including, 3.4.9.2 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page which is the edit users page. This vulnerability was partially patched in version 3.4.9.2, and was fully patched in 3.4.9.3.
