GHSA-965r-9cg9-g42p Valtimo backend libraries allows objects in the object-api to be accessed and modified by unauthorized users

• Maven com.ritense.valtimo:objecten-api: >= 11.0.0.RELEASE, <= 11.3.3.RELEASE (no fix yet) • Maven com.ritense.valtimo:object-management: >= 11.0.0.RELEASE, <= 11.3.3.RELEASE (no fix yet) • Maven com.ritense.valtimo:object-management: >= 12.0.0.RELEASE, < 12.13.0.RELEASE → fixed in 12.13.0.RELEASE • Maven com.ritense.valtimo:objecten-api: >= 12.0.0.RELEASE, < 12.13.0.RELEASE → fixed in 12.13.0.RELEASE

Impact All objects for which an object-management configuration exists can be listed, viewed, edited, created or deleted by unauthorised users. If object-urls are exposed via other channels, the contents of these objects can be viewed independent of object-management configurations. Attack requirements The following conditions have to be met in order to perform this attack: • A user must be logged in • No relevant application roles are required • At least one object-type must be configured via object-management • The scope of the attack is limited to objects that are configured via object-management. • The value of `showInDataMenu` is irrelevant for this attack Patches This issue was patched in version 12.13.0.RELEASE. Workarounds It is possible to override the endpoint security as defined in `ObjectenApiHttpSecurityConfigurer` and `ObjectManagementHttpSecurityConfigurer`. Depending on the implementation, this could result in loss of functionality.
