Credentials Binding Plugin allows specifying passwords and other secrets as environment variables, and will hide them from console output in builds. As a side effect of the fix for SECURITY-698, $
characters in secrets are escaped to $$
. This will then be expanded to $ again once the secret is passed to (post) build steps.
Credentials Binding Plugin 1.22 and earlier does not mask the escaped form of the secret (containing $$
). This occurs for example in the \"Execute Maven top-level targets\" build step included in Jenkins.\n\nCredentials Binding Plugin 1.23 now masks secrets both in their original form and with escaped $
characters, so they will be masked even if printed before value expansion.
