Detailsinfo

A vulnerability was found in GitoxideLabs gitoxide up to 0.49.0. It has been rated as problematic. This issue affects an unknown functionality of the component gix-url. The manipulation with an unknown input leads to a improper authorization vulnerability. Using CWE to declare the problem leads to CWE-285. The product does not perform or incorrectly performs an authorization check when an actor attempts to access a resource or perform an action. Impacted is confidentiality. The summary by CVE is:

gitoxide's gix-url crate (<= 0.32.0, fixed in 0.37.1) uses a hand-rolled URL parser that does not treat '?' or '#' as terminating the authority component, contrary to RFC 3986. As a consequence, gix-transport's HTTP redirect identity guard (can_reuse_identity) compares the wrong host and fails open. An attacker controlling a redirect response can craft a Location header of the form <attacker-authority>?@<original-authority> so that gitoxide sends the caller's HTTP Basic Authorization credentials to an unintended host. gix-transport is affected in versions <= 0.49.0 (fixed in 0.58.1).

It is possible to read the advisory at github.com. The identification of this vulnerability is CVE-2026-82247 since 08/28/2026. The exploitation is known to be easy.
