CyberRota Analysis
AI-GeneratedThe isomorphic-git library prior to version 1.42.0 is vulnerable to a prototype pollution attack via the getRemoteInfo function, allowing malicious Git server operators to manipulate Object.prototype by using crafted ref names with '__proto__' segments. This exploitation can lead to credential leakage, as it enables attackers to reroute network operations through a proxy they control, potentially exposing sensitive authentication information. Developers and organizations utilizing isomorphic-git should prioritize updating to the latest version to mitigate this high-severity vulnerability.

Original NVD Description
isomorphic-git before 1.42.0 contains a prototype pollution vulnerability in the getRemoteInfo function that allows a malicious Git server operator to pollute Object.prototype by advertising crafted ref names containing '__proto__' path segments during ref negotiation. Attackers controlling a Git server can advertise a specially crafted ref such as '__proto__/corsProxy' to reroute all subsequent network operations through an attacker-controlled proxy, causing isomorphic-git to invoke the victim's onAuth callback and transmit credentials to the attacker when the victim calls getRemoteInfo with an attacker-supplied URL.
