VLAI
Details

The GamiPress – Gamification plugin to reward points, achievements, badges & ranks in WordPress plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 7.9.4 via the 'access' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to view private GamiPress activity log entries belonging to any user, including badge earnings, points balance changes, and event records from integrated plugins such as WooCommerce, LearnDash, and BuddyPress. This is exploitable by any unauthenticated visitor because the required 'gamipress' nonce is broadcast to all front-end users via wp_localize_script on the wp_enqueue_scripts hook, making the sole authentication barrier trivially bypassable.

Details

Authorization Bypass Through User-Controlled Key (CWE-639) in Kibana can lead to information disclosure via Accessing Functionality Not Properly Constrained by ACLs (CAPEC-1). An authenticated user who is authorized to read alerting rules in a single Kibana space could retrieve alerting rule execution telemetry that belongs to spaces the user is not authorized to access. The disclosed telemetry includes rule identifiers, rule names, space identifiers, execution outcomes, timestamps, and execution counters.

GHSA-HF4F-66QC-R3JH

Vulnerability from github – Published: 2026-09-07 15:33 – Updated: 2026-09-07 15:33
VLAI
Details

Affected versions of MISP allow authenticated users to retrieve object-reference records by UUID through EventGraphTool::get_reference_data() without first checking whether the requester is authorized to view the object the reference belongs to.

The vulnerable code queried ObjectReference.uuid directly and returned the matching row whenever it existed. Because no parent-object ACL was applied, a user who knew or obtained a reference UUID could retrieve information associated with an object outside their normal access scope. The commit explicitly states that any object reference could be returned by UUID without authorizing its parent object.

The fix retrieves the referenced object's object_id and calls fetchObjectSimple() with the current user. If the user cannot access that parent object, MISP now returns NotFoundException instead of exposing the reference.

Version affected: ≤2.5.45

Mitigation
Architecture and Design

For each and every data access, ensure that the user has sufficient privilege to access the record that is being requested.

Mitigation
Architecture and Design Implementation

Make sure that the key that is used in the lookup of a specific user's record is not controllable externally by the user or that any tampering can be detected.

Mitigation
Architecture and Design

Use encryption in order to make it more difficult to guess other legitimate values of the key or associate a digital signature with the key so that the server can verify that there has been no tampering.

No CAPEC attack patterns related to this CWE.
