Vulnerability CVE-2024-6264
Published: 2024-07-02

Description:
The Post Meta Data Manager plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the ??$meta_key?? parameter in all versions up to, and including, 1.2.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
