Description

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.

Affected products

Jenkins: before 2.462.3; before 2.479 — fixed in 2.462.3, 2.479

How to fix

Upgrade to a fixed version: Jenkins 2.462.3, 2.479. Check the vendor advisory for mitigations.
