Security Advisories 🚨

🚨 Escape Sequence Injection vulnerability in Rack lead to Possible Log Injection

Summary

Rack::Sendfile can be exploited by crafting input that includes newline characters to manipulate log entries.

Details

The Rack::Sendfile middleware logs unsanitized header values from the X-Sendfile-Type header. An attacker can exploit this by injecting escape sequences (such as newline characters) into the header, resulting in log injection.

Impact

This vulnerability can distort log files, obscure attack traces, and complicate security auditing.

Mitigation

• Update to the latest version of Rack, or
• Remove usage of Rack::Sendfile.

Release Notes

3.1.11 (from changelog)

Security

• CVE-2025-27111 Possible Log Injection in Rack::Sendfile.

Does any of this look wrong? Please let us know.

Commits

See the full diff on Github. The new version differs by 2 commits:

• Bump patch version.
• Use `#inspect` to prevent log injection.
