———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: ≤2.5.457hCVE-2026-86408——
———Affected versions of MISP do not enforce parent-event visibility when serving cryptographic keys through CryptographicKeysController::view().
The vulnerable handler queried CryptographicKey directly using the supplied key ID and selected sensitive fields such as:
*
type
*
key_data
*
fingerprint
but did not fetch or authorize the associated parent event first.
The upstream commit explicitly states that cryptographicKeys/view could return a protected event’s signing key to any authenticated user.
The fix adds parent_id and parent_type to the lookup and then enforces authorization through the associated event using fetchSimpleEvent($user, parent_id). If the parent is not an Event, access is limited to site administrators.
Version affected: ≤2.5.457hCVE-2026-49455.3 MED—
———The Otter Blocks – Gutenberg Blocks, Page Builder for Gutenberg Editor & FSE plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.1.7 via the 'watch_checkout' function due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to pay for a lower-cost product while obtaining entitlement for a premium product by manipulating the product_id parameter independently of the price_id parameter in the Stripe checkout URL.7hCVE-2026-862777.3 ALT—
