CVE-2026-24525: 
WordPress vulnerability analysis and mitigation

CVE-2026-24525 is a Missing Authorization (Broken Access Control) vulnerability in the CloudPanel CLP Varnish Cache WordPress plugin. It affects all versions through 1.0.2 and was reported by researcher Nabil Irawan on December 27, 2025, with public disclosure on January 23–26, 2026. The vulnerability carries a CVSS v3.1 base score of 5.3 (Medium), assigned by Patchstack, with the patched version being 1.0.3 (Patchstack).

The vulnerability is classified as CWE-862 (Missing Authorization), meaning the plugin fails to perform adequate authorization checks before executing certain privileged actions. This allows unauthenticated network-based attackers to exploit incorrectly configured access control security levels — a pattern consistent with missing nonce token or capability checks in WordPress plugin functions. The attack requires no user interaction, no authentication, and low attack complexity, making it trivially exploitable over the network (Patchstack).

Successful exploitation results in a low availability impact — specifically, unauthenticated attackers can trigger actions related to Varnish Cache management (such as cache purging or manipulation) without proper authorization. There is no confidentiality or integrity impact per the final CVSS scoring. While the individual impact is limited, this type of vulnerability is commonly leveraged in mass-exploit campaigns targeting large numbers of WordPress sites regardless of their size or traffic (Patchstack).

There is no public proof-of-concept exploit code and no evidence of active in-the-wild exploitation at this time. The EPSS score is very low at approximately 0.017%, reflecting a low probability of exploitation in the near term. The vulnerability is not listed in the CISA Known Exploited Vulnerabilities (KEV) catalog. Patchstack classifies this as low priority with unlikely exploitation impact (Patchstack).

The vulnerability is patched in CLP Varnish Cache version 1.0.3. Site administrators should update the plugin immediately to version 1.0.3 or later. Patchstack users can enable auto-update for vulnerable plugins as an additional safeguard. As an interim measure, restrict network-level access to WordPress admin endpoints and review plugin access control configurations (Patchstack).
