How do I fix GHSA-965r-9cg9-g42p?

A fix is available for GHSA-965r-9cg9-g42p; check the affected-versions list above or the advisory for the patched release of com.ritense.valtimo:objecten-api, then make sure no transitive dependency still pins the vulnerable range.

How do I detect GHSA-965r-9cg9-g42p in my Maven dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for com.ritense.valtimo:objecten-api, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate GHSA-965r-9cg9-g42p if there is no patch (or I can't update yet)?

Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Is GHSA-965r-9cg9-g42p actively exploited in the wild?

No public exploit code has been indexed for GHSA-965r-9cg9-g42p yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

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.
