Title
LORIS has incorrect access checks in document_repository
Summary
LORIS (Longitudinal Online Research and Imaging System) is a self-hosted web application that provides data- and project-management for neuroimaging research. From 21.0.0 to before 27.0.3 and 28.0.1, while the document_repository frontend was restricting file access, the backend endpoint was not correctly verifying access permissions. A user could theoretically download a file that they should not have access to, if they know or can brute force the filename. This vulnerability is fixed in 27.0.3 and 28.0.1.

Title
Chyrp Lite has an IDOR via Mass Assignment in Post Model
Summary
Chyrp Lite is an ultra-lightweight blogging engine. Prior to 2026.01, an IDOR / Mass Assignment issue exists in the Post model that allows authenticated users with post editing permissions (Edit Post, Edit Draft, Edit Own Post, Edit Own Draft) to modify posts they do not own and do not have permission to edit. By passing internal class properties such as id into the post_attributes payload, an attacker can alter the object being instantiated. As a result, further actions are performed on another user’s post rather than the attacker’s own post, effectively enabling post takeover. This vulnerability is fixed in 2026.01.

Title
InvenTree has Arbitrary API Token Creation
Summary
InvenTree is an Open Source Inventory Management System. From 0.16.0 to before 1.2.7, any authenticated InvenTree user can create a valid API token attributed to any other user in the system — including administrators and superusers — by supplying the target's user ID in the user field of a POST /api/user/tokens/ request. The returned token is immediately usable for full API authentication as the target user, from any network location, with no further interaction required. This vulnerability is fixed in 1.2.7 and 1.3.0.

Title
Tandoor Recipes — `amount`/`unit` bypass serializer in `food/{id}/shopping/`
Summary
Tandoor Recipes is an application for managing recipes, planning meals, and building shopping lists. Prior to 2.6.4, the POST /api/food/{id}/shopping/ endpoint reads amount and unit directly from request.data and passes them without validation to ShoppingListEntry.objects.create(). Invalid amount values (non-numeric strings) cause an unhandled exception and HTTP 500. A unit ID from a different Space can be associated cross-space, leaking foreign-key references across tenant boundaries. All other endpoints creating ShoppingListEntry use ShoppingListEntrySerializer, which validates and sanitizes these fields. This vulnerability is fixed in 2.6.4.

Title
FreeScout has an Unauthenticated IDOR in Open Tracking Endpoint Allows Cross-Conversation Thread Manipulation and Enumeration
Summary
FreeScout is a free help desk and shared inbox built with PHP's Laravel framework. Prior to 1.8.212, the endpoint GET /thread/read/{conversation_id}/{thread_id} does not require authentication and does not validate whether the given thread_id belongs to the given conversation_id. This allows any unauthenticated attacker to mark any thread as read by passing arbitrary IDs, enumerate valid thread IDs via HTTP response codes (200 vs 404), and manipulate opened_at timestamps across conversations (IDOR). This vulnerability is fixed in 1.8.212.

Title
MStore API <= 4.18.3 - Authenticated (Subscriber+) Insecure Direct Object Reference to Arbitrary User Meta Update
Summary
The MStore API plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.18.3. This is due to the update_user_profile() function in controllers/flutter-user.php processing the 'meta_data' JSON parameter without any allowlist, blocklist, or validation of meta keys. The function reads raw JSON from php://input (line 1012), decodes it (line 1013), authenticates the user via cookie validation (line 1015), and then directly iterates over the user-supplied meta_data array passing arbitrary keys and values to update_user_meta() (line 1080) with no sanitization or restrictions. This makes it possible for authenticated attackers, with Subscriber-level access and above, to modify arbitrary user meta fields on their own accounts, including sensitive fields like wp_user_level (to escalate to administrator-level legacy checks), plugin-specific authorization flags (e.g., _wpuf_user_active, aiowps_account_status), and billing/profile fields with unsanitized values (potentially enabling Stored XSS in admin contexts). Note that wp_capabilities cannot be directly exploited this way because it requires a serialized array value, but wp_user_level (a simple integer) and numerous plugin-specific meta keys are exploitable.

Title
Keycloak: org.keycloak.services: keycloak: information disclosure via evaluate-scopes admin api
Summary
A flaw was found in Keycloak. A low-privilege administrator with the 'view-clients' role can exploit this by invoking the 'evaluate-scopes' Admin API endpoints with an arbitrary user ID (userId) parameter. This vulnerability allows for cross-role personally identifiable information (PII) leakage, enabling unauthorized visibility into user identities and authorizations across the realm. Exploitation is possible remotely via network access to the Admin API.

CVE-2026-39331 (GCVE-0-2026-39331)

Vulnerability from cvelistv5 – Published: 2026-04-07 17:36 – Updated: 2026-04-07 18:39

Title
ChurchCRM has an API Authorization Bypass Allows Authenticated User to Deactivate, Modify, and Spam Arbitrary Families
Summary
ChurchCRM is an open-source church management system. Prior to 7.1.0, an authenticated API user can modify any family record's state without proper authorization by simply changing the {familyId} parameter in requests, regardless of whether they possess the required EditRecords privilege. /family/{familyId}/verify, /family/{familyId}/verify/url, /family/{familyId}/verify/now, /family/{familyId}/activate/{status}, and /family/{familyId}/geocode lack role-based access control, allowing users to deactivate/reactivate arbitrary families, spam verification emails, and mark families as verified and trigger geocoding. This vulnerability is fixed in 7.1.0.

Mitigation

Phase: Architecture and Design

Description:

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

Phases: Architecture and Design, Implementation

Description:

  • 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

Phase: Architecture and Design

Description:

  • 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.
