CVE-2025-23040

Credential theft via remote URL host confusion

Published Jan 15, 2025 · Updated Jan 15, 2025

Credential exposure in GitHub Desktop 3.3.15 through 3.4.11 allows attackers to steal stored Git credentials via crafted remote URLs. GitHub Desktop misinterprets Git credential requests derived from a malicious remote URL and supplies credentials for a different host to the server Git is contacting. A user must clone an attacker-controlled repository directly or through a submodule, exposing a GitHub username and OAuth token or other stored remote-host credentials.
