CVE-2025-12160

Name of the Vulnerable Software and Affected Versions Simple User Registration versions up to and including 6.6

Description The Simple User Registration plugin for WordPress is susceptible to Stored Cross-Site Scripting. This is due to insufficient input sanitization and output escaping in the wpr admin msg parameter. This allows unauthenticated attackers to inject arbitrary web scripts into pages, which will execute when a user accesses the injected page.

Recommendations Update Simple User Registration to a version newer than 6.6.
