This makes it possible for unauthenticated attackers to upload arbitrary files on the affected site's server which may make remote code execution possible. The vulnerability can only be exploited if \"Host Files Locally - Gravatars\" is enabled, which is disabled by default.","cwes":["CWE-434"],"vendors":[{"vendor":"cloudflare","status":"none","basis":"claimed","firstOn":null,"firstIsNew":false,"daysToRule":null,"daysAtMost":null,"freePlan":false,"claims":[]},{"vendor":"aws","status":"none","basis":"claimed","firstOn":null,"firstIsNew":false,"daysToRule":null,"daysAtMost":null,"freePlan":false,"claims":[]},{"vendor":"azure","status":"none","basis":"claimed","firstOn":null,"firstIsNew":false,"daysToRule":null,"daysAtMost":null,"freePlan":false,"claims":[]},{"vendor":"google","status":"none","basis":"claimed","firstOn":null,"firstIsNew":false,"daysToRule":null,"daysAtMost":null,"freePlan":false,"claims":[]},{"vendor":"fastly","status":"no_history","basis":"claimed","firstOn":null,"firstIsNew":false,"daysToRule":null,"daysAtMost":null,"freePlan":false,"claims":[]},{"vendor":"f5","status":"rule","basis":"claimed","firstOn":"2026-07-07","firstIsNew":true,"daysToRule":75,"daysAtMost":null,"freePlan":false,"claims":[{"id":"b5fc185d2881fd1c0a23735a116c4c4956a5c751b02367270cf570a315af9fcd","cve_id":"CVE-2026-3844","vendor":"f5","product":"Attack signatures","rule_id":"200020243","rule_name":"Breeze Cache Arbitrary File Upload","change":"new","default_action":null,"published_on":"2026-07-07","source_url":"https://docs.cloud.f5.com/docs-v2/platform/changelogs/security-details-changelog","source_title":"F5 Distributed Cloud attack signatures changelog","excerpt":"Added: signature 200020243 \"Breeze Cache Arbitrary File Upload\" (Malicious File Upload, risk Medium), systems: WordPress.
