Description

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 WordPress components

A confirmed match is backed by the plugin or theme slug. A possible match is based on the product name only and should be verified.

Affected products and versions

  • sasiddiqui Custom Permalinks — Up to and including 2.6.0
  • sami_ahmed_siddiqui custom_permalinks — Up to and including 2.6.0
  • samiahmedsiddiqui custom_permalinks — Before 2.7.0
