{"id":"CVE-2026-10795","aliases":[],"url":"https://o3.security/vulnerability/CVE-2026-10795","summary":"The UpdraftPlus: WP Backup & Migration Plugin plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.26.4 via the UpdraftPlus_Remote_Communications_V2::wp_loaded…","details":"The UpdraftPlus: WP Backup & Migration Plugin plugin for WordPress is vulnerable to Authentication Bypass in all versions up to, and including, 1.26.4 via the UpdraftPlus_Remote_Communications_V2::wp_loaded function. 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.","published":"2026-06-11T07:16:26.713","modified":"2026-07-23T09:10:00.113","cvss":{"score":8.1,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.svn.wordpress.org/updraftplus/tags/1.26.4/vendor/team-updraft/common-libs/src/updraft-rpc/class-udrpc.php"},{"type":"WEB","url":"https://plugins.svn.wordpress.org/updraftplus/tags/1.26.4/vendor/team-updraft/common-libs/src/updraft-rpc/class-udrpc2.php"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset/3561938/updraftplus/trunk/vendor/team-updraft/common-libs/src/updraft-rpc/class-udrpc2.php"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/e901c2a0-2477-4b9a-8483-6002419e0a2f?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-07-23T09:10:00.113"}}
