Bump cowboy/cowlib for hex.audit security advisories - #148
Merged
Conversation
Fixes the HPACK/QPACK memory-exhaustion DoS (CVE-2026-59248, HIGH) and cowboy's duplicate-header max_headers bypass (CVE-2026-65624). Two residual cowlib advisories have no fixed release upstream yet. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

mix deps.update cowboy cowlib(lockfile only, no constraint changes): cowboy 2.17.0 → 2.18.0, cowlib 2.18.0 → 2.19.0, plus transitive ranch 2.2.0 → 2.2.1.Fixed
max_headersbypass via duplicate header names → fixed in cowboy 2.18.0Residual (no fix released upstream)
mix hex.auditstill flags cowlib for EEF-CVE-2026-43966 (MEDIUM, response splitting via non-VCHAR bytes incow_http_struct_hd:escape_string/2) and EEF-CVE-2026-43969 (LOW, cookie header injection viacow_cookie:cookie/1). Per OSV, every cowlib ≥ 2.9.0 is affected and no patched release exists yet — 2.19.0 is the latest. Both require the app to reflect attacker-controlled data into response cookies/structured headers, which our LAN-only LiveView UI doesn't do; worth re-checking on the next cowlib release.Verification
