Vulnerabilities

n8n is an open source workflow automation platform. Prior to 2.27.4 and 2.28.1, the AI Agents feature did not enforce the Allowed HTTP Request Domains restriction configured on credentials when an MCP tool was pointed at an arbitrary URL, allowing a member-level user with use-only access to a shared credential to send its secret to an external server they control. This issue is fixed in versions 2.27.4 and 2.28.1.

n8n is an open source workflow automation platform. Prior to 1.123.61, 2.27.4, and, 2.28.1, an authenticated user with the default workflow:create permission could pollute Object.prototype through a crafted workflow saved, updated, or imported via the workflow API, allowing unauthenticated requests to be treated as a privileged user and exposing user and project listing endpoints. This issue is fixed in versions 1.123.61, 2.27.4, and 2.28.1.

n8n is an open source workflow automation platform. Prior to 2.27.4 and from 2.28.0 prior to 2.28.1, n8n instances configured with more than one trusted token-exchange issuer resolved external identities to local accounts using only the JWT sub claim and ignored the iss claim, allowing an attacker with a valid token from one trusted issuer and a sub matching a victim under another issuer to authenticate as that victim. This issue is fixed in versions 2.27.4 and 2.28.1.

A security flaw has been discovered in enquirer up to 2.4.1. Affected is the function Enquirer.set of the component Public Package API. The manipulation of the argument question.name results in improperly controlled modification of object prototype attributes. The attack can be launched remotely. The exploit has been released to the public and may be used for attacks. The project was informed of the problem early through an issue report.

A weakness has been identified in manjurulhoque django-job-portal up to dfa352f305bba44445ac5dc12e9b2a98c9dcd71f. Affected by this vulnerability is the function EditEmployeeProfileAPIView of the file accounts/api/views.py of the component Employee Dashboard Endpoint. This manipulation of the argument role causes improper access controls. The attack may be initiated remotely. The exploit has been made available to the public and could be used for attacks. This product uses a rolling release model to deliver continuous updates. As a result, specific version information for affected or updated releases is not available. The project was informed of the problem early through an issue report but has not responded yet.

When oxenstored is tearing a domain down, the node data is cleaned up<br /> but the usage counts are leaked.<br /> <br /> When the domain ID is eventually reused, the new domain can create fewer<br /> nodes before beeing deemed to be over quota.
