Information disclosure in Renovatebot Renovate
CVE-2020-37267
Renovate versions >=19.180.0 and <23.25.1, when used with Azure DevOps, may expose the bot's authorization token in server or pipeline logs because the git http.extraheader=AUTHORIZATION parameter is logged without redaction. Anyone with access to saved logs could obtain the bot credentials. Fixed in 23.25.1; Azure DevOps users should revoke and regenerate credentials if logs may have been exposed.
