Proposing a fix for something flagged in
mix.lock. It is around line 27.plug_cowboy 2.7.4 calls
String.to_atom/1on the value returned by:cowboy_req.scheme/1. For HTTP/2 the scheme comes from an untrusted pseudo‑header, so an attacker can send a large number of unique scheme strings. Each call creates a new atom, which is never garbage‑collected, eventually exhausting the BEAM atom table (default 1,048,576 entries) and causing the VM to abort with asystem_limiterror. This results in a complete denial‑of‑service of the node. The issue is high severity because it can be triggered remotely without authentication and leads to total service outage. Upgrade to plug_cowboy ≥ 2.8.1 or apply a patch that avoids converting untrusted input into atoms.Updates four vulnerable dependencies in mix.lock to versions that fix the reported CVEs, preserving all other dependency specifications.
For reference: rule
CVE-2026-32688. Rated high.I do not know the codebase, so please check the change fits how the rest of it works. Happy to adjust it or close this if the reasoning is off.
Found with automated scanning (RedGem) and reviewed before opening. If it is not useful, closing it is completely fine.
