CVE-2023-0926: Samiahmedsiddiqui Custom Permalinks

Medium severity, CVSS 5.4. EPSS: 0.3% chance of exploitation in the next 30 days.

The Custom Permalinks plugin for WordPress is vulnerable to Stored Cross-Site Scripting in versions up to, and including, 2.6.0 due to insufficient input sanitization and output escaping on tag names. This allows authenticated users, with editor-level permissions or greater to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page, even when 'unfiltered_html' has been disabled.

Affected products

• Samiahmedsiddiqui Custom Permalinks: before 2.7.0 (fixed in 2.7.0)
