This is due to insufficient validation of the remote communications message format, where signature verification can be bypassed and unchecked decryption return values collapse to a predictable all-zero encryption key. This makes it possible for unauthenticated attackers to forge arbitrary RPC commands and run them as the connected administrator, such as uploading and activating a malicious plugin, which ultimately leads to remote code execution.","cwes":["CWE-347"],"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":"2026-09-16","firstIsNew":true,"daysToRule":97,"daysAtMost":null,"freePlan":false,"claims":[{"id":"dce855533053d07849045d8722864b6f01f504b4e114ec9c4e3947740e0987a6","cve_id":"CVE-2026-10795","vendor":"f5","product":"Attack signatures","rule_id":"200013199","rule_name":"WordPress UpdraftPlus Authentication Bypass","change":"new","default_action":null,"published_on":"2026-09-16","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 200013199 \"WordPress UpdraftPlus Authentication Bypass\" (Authentication/Authorization Attacks, risk High), systems: WordPress.
