CVE-2023-6495

Name of the Vulnerable Software and Affected Versions YARPP – Yet Another Related Posts Plugin versions up to and including 5.30.9

Description The issue is related to Stored Cross-Site Scripting via admin settings due to insufficient input sanitization and output escaping. This allows authenticated attackers with administrator-level permissions and above to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The issue only affects multi-site installations and installations where unfiltered html has been disabled.

Recommendations For versions up to and including 5.30.9, update to a version that includes the necessary input sanitization and output escaping fixes to prevent Stored Cross-Site Scripting attacks. As a temporary workaround, consider restricting administrator-level permissions and above to minimize the risk of exploitation. Additionally, enabling unfiltered html, if possible, may help mitigate the issue in some installations.
