What is CVE-2020-37267?

A vulnerability exists in Renovate versions 19.180.0 to 23.25.1 when integrated with Azure DevOps, where the bot’s authorization token may be inadvertently exposed in server or pipeline logs. The git http.extraheader=AUTHORIZATION parameter is incorrectly logged without necessary redaction, allowing anyone with access to the logs to retrieve sensitive bot credentials. It is advised for Azure DevOps users to revoke and regenerate credentials if logs may have been compromised. The issue has been addressed in version 23.25.1.
