Name of the Vulnerable Software and Affected Versions GitHub Branch Source (affected versions not specified)

Description The issue concerns a lack of permission checks in GitHub Branch Source, allowing users with Overall/Read permission to obtain a list of valid credential IDs. This could be exploited, in conjunction with another vulnerability, to capture credentials. The estimated number of potentially affected devices worldwide is not available. There is no information about real-world incidents where this issue was exploited.

Recommendations For GitHub Branch Source, to mitigate the issue, consider requiring Extended Read permission (when enabled) or Configure permission to access credential IDs in the context of a job. If no job context exists, require Overall/Administer permission. At the moment, there is no information about a newer version that contains a fix for this vulnerability.
