This flaw stems from the lack of file type validation within the \u0026lsquo;fetch_gravatar_from_remote\u0026rsquo; function. An unauthenticated attacker can exploit this vulnerability to upload arbitrary files to the affected WordPress site\u0026rsquo;s server. Successful exploitation could lead to remote code execution on the server. It is important to note that the vulnerability can only be exploited if the \u0026ldquo;Host Files Locally - Gravatars\u0026rdquo; setting is enabled within the Breeze Cache plugin. This setting is disabled by default, reducing the attack surface. Defenders should prioritize identifying potentially compromised systems running vulnerable versions of Breeze Cache with the \u0026ldquo;Host Files Locally - Gravatars\u0026rdquo; option enabled.\u003c/p\u003e\n\u003ch2 id=\"attack-chain\"\u003eAttack Chain\u003c/h2\u003e\n\u003col\u003e\n\u003cli\u003eAn unauthenticated attacker identifies a WordPress site running a vulnerable version (\u0026lt;= 2.4.4) of the Breeze Cache plugin.\u003c/li\u003e\n\u003cli\u003eThe attacker confirms the \u0026ldquo;Host Files Locally - Gravatars\u0026rdquo; option is enabled on the target WordPress site.\u003c/li\u003e\n\u003cli\u003eThe attacker crafts a malicious HTTP request targeting the \u0026lsquo;fetch_gravatar_from_remote\u0026rsquo; function.
