{"id":"CVE-2026-104068","kind":"vulnerability","aliases":["CVE-2026-104068"],"related":[],"title":"JetBackup WordPress plugin: crafted backup archive writes files outside restore folder","description":"JetBackup plugin for WordPress before 3.1.24.10 contains a symlink-based arbitrary file write vulnerability that allows an authenticated WordPress administrator to write attacker-controlled file contents outside the intended restore destination during backup import and restore. Attackers can craft a backup archive containing a symbolic link that archive extraction follows without validating targets or enforcing destination containment, potentially leading to server-side code execution depending on the writable destination and server configuration.","summary":"The JetBackup plugin for WordPress before 3.1.24.10 follows symbolic links inside imported or restored backup archives without checking where they point.
