Jenkins Shared Library Version Override Plugin 17.v786074c9fce7 and earlier declares folder-scoped library overrides as trusted, so that they're not executed in the Script Security sandbox, allowing attackers with Item/Configure permission on a folder to configure a folder-scoped library override that runs without sandbox protection. This allows attackers with Item/Configure permission on a folder to configure a folder-scoped library override that runs without sandbox protection.
