CVE-2026-82249: gitoxide before 0.38.2 Credential Helper Protocol Field Injection
gitoxide before 0.38.2 fails to validate carriage return characters in URL values passed to credential helpers. Attackers can supply URLs containing bare carriage returns to inject additional helper protocol fields and cause credential helpers to return credentials for attacker-specified hosts instead of the requested URL.

Event History
Frequently Asked Questions
Which installations are affected?
gitoxide versions earlier than 0.38.2 are affected.
What does an attacker need to exploit this issue?
The attacker must be able to supply a URL containing bare carriage return characters to the credential-helper path. Exploitation is rated network-accessible, requires high attack complexity, and requires user interaction, but does not require privileges.
What is the practical impact on credentials?
Injected helper protocol fields can cause a credential helper to return credentials for an attacker-specified host instead of the requested URL. The reported impact is limited to confidentiality.
