Description
The Breeze Cache plugin for WordPress contains a critical vulnerability (CVE-2026-3844) that allows unauthenticated attackers to upload arbitrary files due to missing file type validation in the 'fetch_gravatar_from_remote' function. This issue affects all versions up to and including 2.4.4 and can lead to remote code execution if exploited. Exploitation requires the 'Host Files Locally - Gravatars' setting to be enabled, which is disabled by default. The vulnerability has a high CVSS score of 9.8, indicating severe impact on confidentiality, integrity, and availability.
