Summary

isomorphic-git < 1.42.0 Prototype Pollution via getRemoteInfo

Details

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.
