Credential theft via redirect URL validation
Published Aug 28, 2026 · Updated Aug 28, 2026
Credential exposure in GitoxideLabs gitoxide gix-transport 0.25.4 through 0.55.0 allows remote attackers to steal credentials via redirects. add_basic_auth_if_present() validates the original URL and attaches authorization data after swap_tails() rewrites a later request to the redirected host. A user or pipeline must initiate an authenticated HTTP(S) clone or fetch with the curl backend; the reqwest backend is unaffected.
