Vulnerability description
DayBreach CVE AI Research
CVE-2026-54171 has vendor, distribution, patch and security-source records on file. We can compare them and prepare an explanation linked to the evidence.
Excon is usable, fast, simple HTTP 1.1 for Ruby. Prior to 1.5.0, Excon's RedirectFollower middleware failed to strip additional sensitive headers when following redirects and did not provide a custom list of headers to strip. This could cause inadvertent leakage of sensitive data when the initial request includes header information that is not intended for the new target. This issue is fixed in version 1.5.0.
