Title
n8n before 1.123.64, 2.29.8, and 2.30.1 Privilege Escalation via SSO Instance-Role
Summary
n8n versions before 1.123.64, 2.29.8, and 2.30.1 contain a privilege escalation vulnerability in Enterprise SSO instance-role provisioning. The provisioning path maps an IdP-asserted role claim to an n8n global role but does not prevent assignment of the global:owner role (unlike the token-exchange identity path, which rejects it). An SSO-authenticated user whose instance-role claim resolves to global:owner is provisioned as instance owner, gaining full administrative control over workflows, credentials, users, and instance configuration. Exploitation requires that Enterprise SSO is configured, instance-role provisioning is enabled via N8N_SSO_SCOPES_PROVISION_INSTANCE_ROLE (disabled by default), and the attacker controls the instance-role claim value issued by the IdP.

Title
Onlook tRPC Insecure Direct Object Reference via multiple procedures
Summary
Onlook through 0.2.32, fixed in commit 423e2e9, contains a broken object level authorization vulnerability that allows authenticated attackers to access and manipulate other users' resources by supplying arbitrary UUID values to tRPC API procedures including project.get, member.remove, and chat.conversation.delete. Attackers can provide arbitrary projectId or conversationId values without authorization validation to read, modify, and delete other users' project data, members, and conversation history.

Title
Insecure Direct Object Reference in ATutor
Summary
ATutor is vulnerable to Insecure Direct Object Reference (IDOR) attack in profile picture related endpoints. Any authenticated user, including a student, can supply another user's member_id in a POST request to the profile album endpoint and permanently delete that user's profile picture, including those of instructors and administrators.
Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.

Title
Authentication Bypass in ATutor
Summary
ATutor is vulnerable to authentication bypass . Although a token validation check is present in the auto-login functionality, the values required for token validation remain uninitialized in certain code paths. An unauthenticated attacker who can determine a user's identifier and registration timestamp can generate a valid token and authenticate as an existing user, including administrator, without knowing the password.
Product is no longer actively supported and the vulnerabilities have not been fixed. Only version 2.2.4 was tested and confirmed as vulnerable, other versions were not tested but might also be vulnerable.

Title
Multicloud-operators-channel: multicloud-operators-channel: cross-namespace secret and configmap mutation via spec.secretref.namespace confused deputy
Summary
A flaw was found in the multicloud-operators-channel component. This vulnerability allows a user with specific permissions to manipulate how the system handles sensitive information, known as Secrets, across different parts of the system (namespaces). By exploiting this, an attacker can modify these Secrets in unauthorized areas. This could lead to unauthorized access to information or elevated privileges within the system.

Title
Statamic: Missing authorization on navigation endpoint allows disclosure of restricted entries
Summary
Statamic is a Laravel and Git powered content management system (CMS). Prior to 5.74.1 and 6.24.0, an authenticated Control Panel user could view content from entries they did not have permission to view, including entry content and custom field values, from any collection and including unpublished entries, through the navigation endpoint, though no data could be modified. This issue is fixed in versions 5.74.1 and 6.24.0.

Title
SurrealDB before 2.5.0 Privilege Escalation via Future Fields
Summary
SurrealDB before 2.5.0 and before 3.0.0-beta.3 contains a confused deputy privilege escalation vulnerability. Unprivileged users (e.g., those with the database editor role) can create or modify fields containing futures, functions, or closures. Because these are executed in the context of the invoking/querying user rather than their creator, an attacker can plant malicious logic that executes with a higher-privileged user's permissions when that user reads or writes the affected record. This can lead to full privilege escalation, including creation of a root owner and server takeover.

Title
SurrealDB before 3.1.0 Authorization Bypass via Composite Record-id
Summary
SurrealDB versions before 3.1.0 contain an authorization bypass vulnerability where authenticated users can spoof composite record-id field values by writing to editable body fields. Attackers can bypass permission rules that gate access on id components like tenant isolation by setting same-named body fields to spoofed values that permission checks incorrectly read instead of the immutable id key.

Title
SurrealDB before 3.2.0 Authentication Bypass via Custom API
Summary
SurrealDB versions before 3.2.0 fail to validate namespace and database scope in custom API routes, allowing authenticated users to invoke endpoints in different namespaces/databases. Attackers with valid credentials for any namespace/database can access custom API endpoints in other tenants by specifying the target scope in the URL path, reading sensitive data or triggering unintended operations.

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.
