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.

Affected products

JetBackup: before 3.1.24.10 — fixed in 3.1.24.10

How to fix

Upgrade to a fixed version: JetBackup 3.1.24.10. Check the vendor advisory for mitigations.
