Title
Plane IDOR: Cross-Project Issue Date Modification via Bulk Update Endpoint
Summary
Plane is an an open-source project management tool. Prior to 1.3.0, the IssueBulkUpdateDateEndpoint allows a project member (ADMIN or MEMBER) to modify the start_date and target_date of ANY issue across the entire Plane instance, regardless of workspace or project membership. The endpoint fetches issues by ID without filtering by workspace or project, enabling cross-boundary data modification. This vulnerability is fixed in 1.3.0.

Title
Scoold has an Authenticated Arbitrary Question Overwrite via Client-Controlled postId in POST /questions/ask
Summary
Scoold is a Q&A and a knowledge sharing platform for teams. Prior to 1.66.2, an authenticated authorization flaw in Scoold allows any logged-in, low-privilege user to overwrite another user's existing question by supplying that question's public ID as the postId parameter to POST /questions/ask. Because question IDs are exposed in normal question URLs, a low-privilege attacker can take a victim question ID from a public page and cause attacker-controlled content to be stored under that existing question object. This causes direct integrity loss of user-generated content and corrupts the integrity of the existing discussion thread. This vulnerability is fixed in 1.66.2.

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.

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-2026-35584 (GCVE-0-2026-35584)

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.

CVE-2026-35489 (GCVE-0-2026-35489)

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.

CVE-2026-35478 (GCVE-0-2026-35478)

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
OpenCTI: Authorization Bypass via `synchronized-upsert` HTTP Header Injection
Summary
OpenCTI is an open source platform for managing cyber threat intelligence knowledge and observables. Prior to 7.260326.0, an authorization bypass vulnerability in OpenCTI allows any authenticated user with KNOWLEDGE_KNUPDATE permission to bypass Confidence Level validation and Object Marking restrictions by injecting the synchronized-upsert: true HTTP header, enabling attackers to downgrade confidence levels, remove security markings such as TLP:RED, manipulate relationships, and affect STIX object types including Indicators, ThreatActors, Malware, and Reports. This issue is fixed in version 7.260326.0.

Title
Brave CMS has an Insecure Direct Object Reference in Article Image Deletion
Summary
Brave CMS is an open-source CMS. Prior to 2.0.6, an Insecure Direct Object Reference (IDOR) vulnerability exists in the article image deletion feature. It is located in app/Http/Controllers/Dashboard/ArticleController.php within the deleteImage method. The endpoint accepts a filename from the URL but does not verify ownership. This allows an authenticated user with edit permissions to delete images attached to articles owned by other users. This vulnerability is fixed in 2.0.6.

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.
