Security Advisories 🚨

🚨 Rack ReDoS Vulnerability in HTTP Accept Headers Parsing

Summary

A Regular Expression Denial of Service (ReDoS) vulnerability exists in the Rack::Request::Helpers module when parsing HTTP Accept headers. This vulnerability can be exploited by an attacker sending specially crafted Accept-Encoding or Accept-Language headers, causing the server to spend excessive time processing the request and leading to a Denial of Service (DoS).

Details

The fix for GHSA-54rr-7fvw-6x8f was not applied to the main branch and thus while the issue was fixed for the Rack v3.0 release series, it was not fixed in the v3.1 release series until v3.1.5.

Release Notes

3.1.6 (from changelog)

• Fix several edge cases in Rack::Request#parse_http_accept_header's implementation. (#2226, @ioquatix)

3.1.5 (from changelog)

Security

3.1.4 (from changelog)
