PSC, Research URL: PSC-2026-64631
Home page URL: Security reports for Cloudflare
Application: Cloudflare
Date: Mar 27, 2026
Research Description: CDN and caching integrations are security-relevant because they introduce privileged configuration flows inside wp-admin, handle API tokens, and can directly affect availability and security posture at the edge. If access control, request integrity, or output handling is weak, attackers may force cache purges or mode changes via CSRF, expose sensitive integration metadata, or manipulate settings that impact how the site is protected and cached. Cloudflare version 4.14.2 has successfully completed the CleanTalk Plugin Security Certification process and received PSC-2026-64631, confirming that the plugin was reviewed from a secure code perspective with attention to the most common exploitation paths for CDN, caching, and edge-security integration plugins.
Affected versions: Min 4.14.3, max 4.14.3.
Status: SAFE & CERTIFIED
