Type:
security
Severity:
Important
Release date:
2026-10-02 20:22:48 UTC
Description:
- CVE-2026-55677: stop unescaping the static file wildcard by default in Static, StaticFS, Group.StaticFS and StaticWithConfig of the vendored github.com/labstack/echo/v4 (the echo v4.15.4 fix), so an encoded separator (%2F, %5C) or dot-segment (%2E%2E) cannot resolve a static file outside the route the router matched and bypass route-level middleware; unescaping is opt-in via EnablePathUnescapingStaticFiles and StaticConfig.EnablePathUnescaping
CVEs fixed:
