Technical Summary
The NGINX Cache Optimizer plugin for WordPress contains a missing authorization vulnerability (CWE-862) in the 'nginxcacheoptimizer-blacklist-update' AJAX action. This flaw allows any authenticated user with at least Subscriber privileges to add URLs to the dynamic caching exclusion list without proper capability checks. The vulnerability affects all versions up to and including 1.1. The CVSS 3.1 base score is 4.3, reflecting a network attack vector with low complexity, requiring privileges, no user interaction, unchanged scope, no confidentiality or availability impact, and limited integrity impact.
Potential Impact
An authenticated attacker with Subscriber-level access or higher can modify the plugin's caching exclusion settings by adding URLs to the blacklist. This unauthorized modification could affect caching behavior, potentially degrading site performance or bypassing caching for certain URLs. There is no direct impact on confidentiality or availability reported.
Mitigation Recommendations
No official patch or fix is currently available for this vulnerability. Users should monitor the vendor's advisory for updates. Until a fix is released, restrict user roles carefully to prevent untrusted users from having Subscriber-level or higher access. Avoid granting unnecessary privileges to reduce risk.
