Title
ShellHub: Cross-tenant IDOR in `GET /api/sessions/:uid` discloses SSH session data
Summary
ShellHub is a centralized SSH gateway. Prior to 0.24.2, GET /api/sessions/:uid returns the full session object for any authenticated caller, without scoping by the caller's tenant. An authenticated user can read session records (SSH username, device UID, remote IP, terminal type, authenticated flag, timestamps) belonging to any other namespace. This vulnerability is fixed in 0.24.2.

MailEnable Enterprise Premium < 10.55 Authorization Bypass via WebAdmin
Summary
MailEnable Enterprise Premium 10.55 and earlier contains an improper authorization vulnerability in the WebAdmin mobile portal that allows attackers to bypass authentication checks by reusing AuthenticationToken cookies generated for low-privileged users. Attackers can obtain a token from the WebMail login endpoint using the PersistentLogin parameter and replay it against the WebAdmin portal to perform highly privileged administrative actions.

Title
e107: Broken Access Control in e107 comment edit allows cross-user comment modification
Summary
e107 is a content management system (CMS). Prior to 2.3.4, a Broken Access Control vulnerability exists in the application, allowing an unauthorized authenticated user to edit comments posted by others. This stems from inadequate server-side access control validation, where the application depends only on a predictable identifier in the request to determine which comment to edit, without confirming the requesting user’s ownership of the comment. This vulnerability is fixed in 2.3.4.
Severity
6.5 (Medium)

Dokploy: Cross-Organization IDOR - Multiple tRPC endpoints missing activeOrganizationId validation
Summary
Dokploy is a free, self-hostable Platform as a Service (PaaS). In 0.19.0 and earlier, the protectedProcedure middleware only verifies the user is authenticated - it does NOT enforce organization scoping. Each endpoint must individually verify the resource's org matches the session's activeOrganizationId. This affects the following endpoints: allByType, killProcess, and removeDeployment in deployment.ts; delete in rollbacks.ts; create, one, update, remove, manualBackupPostgres, MySql, Mariadb, Mongo, Compose, WebServer, and listBackupFiles in backup.ts; list, one, delete, update, runManually, and restoreVolumeBackupWithLogs in volume-backups.ts; getNodes, removeWorker, addWorker, and addManager in cluster.ts; and create in mount.ts.

Outline: IDOR in subscriptions.create allows cross-tenant subscription on private documents (sibling of GHSA-23jj-rp48-w7q7)
Summary
Outline is a service that allows for collaborative documentation. From 0.84.0 to 1.7.0, the subscriptions.create API endpoint in server/routes/api/subscriptions/subscriptions.ts exhibits a broken authorization pattern. When both collectionId and documentId are supplied in the request, the route handler authorizes ONLY the collection branch (line 125 if (collectionId)), while the downstream subscriptionCreator command at server/commands/subscriptionCreator.ts writes the subscription against the documentId (which was never validated). The result is a subscription record pinning the attacker's user to a victim document the attacker has no read access to, on any team in the instance. The schema (server/routes/api/subscriptions/schema.ts) only enforces "at least one of collectionId/documentId" via .refine() — it does NOT enforce mutual exclusivity, so passing both is a valid, schema-conforming request. This vulnerability is fixed in 1.7.1.

WWBN AVideo: IDOR in PayPalYPT agreementCancel.json.php Allows Any Authenticated User to Cancel Arbitrary PayPal Subscription Agreements
Summary
WWBN AVideo is an open source video platform. In versions up to and including 29.0, plugin/PayPalYPT/agreementCancel.json.php cancels a PayPal billing agreement using an attacker-supplied agreement parameter without verifying that the authenticated user owns the agreement. A low-privilege authenticated user who learns or obtains another user's PayPal billing agreement ID can silently suspend the victim's recurring subscription, causing revenue loss to the platform and loss of paid service to the victim. Commit 0da3dcff1eda2f497694bf82b559829471c292c2 contains an updated fix.

Title
Naxclow IoT Platform Authorization bypass through User-Controlled key
Summary
A flaw in Naxclow's platform’s onboarding workflow allows an attacker to replay a confirm-then-bind sequence to silently reassign a device to an arbitrary account. Because the affected endpoints validate request signatures but do not confirm legitimate ownership, an attacker with any account can take over a device without user interaction while the device remains online and unaware.

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.
