Title
snipe-it 7.0.12 through 8.6.3 Authorization Bypass via Importer
Summary
Snipe-IT versions >= 7.0.12 and <= 8.6.3 contain an authorization bypass in the Livewire importer component (App\Livewire\Importer, mounted at the imports.index route). The component only checked the broad 'import' ability at mount time, while its files() and activeFile() computed properties queried the imports table with no owner or company scope. As a result, any authenticated non-superuser holding the import permission could view every Import record on the instance (original filename, file_path, filesize, import_type and creation timestamp) and could invoke the selectFile($id) Livewire action with any auto-incrementing Import ID to load another user's record, exposing its stored preview data (header_row column headers and first_row, the first data row of the CSV). Because import CSVs commonly contain personal data, asset serial numbers and license keys, this discloses sensitive information; in Full Multiple Companies Support (FMCS) deployments the disclosure also crosses company/tenant boundaries. Impact is limited to preview data rather than the full CSV file, and superusers were unaffected. Fixed in version 8.7.0, which scopes non-superuser reads to imports owned by the caller.

AVideo SocialMediaPublisher Missing Authorization via add.json.php
Summary
AVideo through c3edcc274c389816d434acadac07ee78eaf330c1 contains a missing authorization vulnerability in the SocialMediaPublisher plugin's add.json.php endpoint that allows authenticated users to modify other users' OAuth token records. Attackers can supply arbitrary row IDs to overwrite another user's stored access_token and refresh_token, then delete the compromised record to destroy the victim's provider linkage.

WWBN AVideo Missing Authorization via resendRestreamer.json.php
Summary
WWBN AVideo through commit c3edcc274c389816d434acadac07ee78eaf330c1 fails to validate ownership of live_restreams_id in resendRestreamer.json.php, allowing authenticated users with canStream to access other users' restream destinations. Attackers can broadcast their live stream to victim-configured restream destinations by supplying arbitrary live_restreams_id values, hijacking YouTube, Facebook, or Twitch streams using victim stream keys.

Title
Apache Airflow Akeyless provider: Akeyless secrets backend: team-scope guard bypass via user-controlled key
Summary
Apache Airflow Akeyless provider: the Akeyless secrets backend's team-scope guard can be bypassed with a user-controlled key. In a multi-team deployment, a Dag author scoped to one team can supply a Variable key containing a path separator that causes the backend to resolve a secret belonging to a different team, because the lookup path is concatenated from an unvalidated key after the team-scoped lookup misses. The Execution API Variables route accepts a path-shaped key, so this is reachable from ordinary Dag code.
Affects multi-team deployments using the Akeyless secrets backend. Single-team deployments are not affected, as there is no cross-team boundary to cross. This is the same class as CVE-2026-68870, CVE-2026-68871 and CVE-2026-68872 in the Azure Key Vault, Yandex Lockbox and Amazon secrets backends.
Users of apache-airflow-providers-akeyless are recommended to upgrade to version 0.3.1 or later, which fixes the issue.

Title
MISP Event Graph Object Reference Lookup Exposes References from Unauthorized Objects
Summary
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.

Title
MISP Missing Authorization in Cryptographic Key View Exposes Signing Keys from Protected Events
Summary
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.

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.
