If an attempt is made to create an item of a type prohibited by `ACL#hasCreatePermission2` or `TopLevelItemDescriptor#isApplicableIn(ItemGroup)` through the Jenkins CLI or the REST API and either of these checks fail, Jenkins 2.478 and earlier, LTS 2.462.2 and earlier creates the item in memory, only deleting it from disk, allowing attackers with Item/Configure permission to save the item to persist it, effectively bypassing the item creation restriction.

Jenkins 2.478 and earlier, LTS 2.462.2 and earlier does not redact multi-line secret values in error messages generated for form submissions involving the `secretTextarea` form field.

Jenkins 2.470 and earlier, LTS 2.452.3 and earlier does not perform a permission check in an HTTP endpoint, allowing attackers with Overall/Read permission to access other users' "My Views".

Jenkins 2.470 and earlier, LTS 2.452.3 and earlier allows agent processes to read arbitrary files from the Jenkins controller file system by using the `ClassLoaderProxy#fetchJar` method in the Remoting library.
