Name of the Vulnerable Software and Affected Versions The Community by PeepSo plugin for WordPress versions up to, and including, 6.4.6.1

Description The issue is related to Stored Cross-Site Scripting via URLs in posts, comments, and profiles when Markdown support is enabled. This is due to insufficient input sanitization and output escaping, allowing authenticated attackers with Subscriber-level access and above to inject arbitrary web scripts in pages. These scripts will execute whenever a user accesses an injected page.

Recommendations For versions up to, and including, 6.4.6.1, update to a version that addresses the insufficient input sanitization and output escaping issue. As a temporary workaround, consider disabling Markdown support until a patch is available. Restrict access to posts, comments, and profiles to minimize the risk of exploitation. Avoid using URLs in these areas until the issue is resolved.
