- Details
-
Summary
A security vulnerability has been identified in
go-ghthat could leak authentication tokens intended for GitHub hosts to non-GitHub hosts when within a codespace.Details
go-ghsources authentication tokens from different environment variables depending on the host involved:GITHUB_TOKEN,GH_TOKENfor GitHub.com and ghe.comGITHUB_ENTERPRISE_TOKEN,GH_ENTERPRISE_TOKENfor GitHub Enterprise Server
Prior to
2.11.1,auth.TokenForHostcould source a token from theGITHUB_TOKENenvironment variable for a host other than GitHub.com or ghe.com when within a codespace.In
2.11.1,auth.TokenForHostwill only source a token from theGITHUB_TOKENenvironment variable for GitHub.com or ghe.com hosts.Impact
Successful exploitation could send authentication token to an unintended host.
Remediation and mitigation
- Upgrade
go-ghto2.11.1 - Advise extension users to regenerate authentication tokens:
- Advise extension users to review their personal security log and any relevant audit logs for actions associated with their account or enterprise
- Database specific
