Technical Analysis

An incorrect access control vulnerability exists in the /{form}/webhooks/{webhook} endpoint of Deck9 Input version 2.0.1. Authenticated attackers can exploit this flaw to arbitrarily modify or delete webhooks belonging to other tenants by sending crafted requests. This vulnerability is categorized under CWE-284 (Improper Access Control) and has a CVSS 3.1 base score of 8.1, indicating high impact on integrity and availability. No vendor advisory or patch information is currently available, and the product is not a cloud service, so remediation depends on vendor updates.

Potential Impact

The vulnerability allows authenticated users to bypass access controls and modify or delete webhooks of other tenants. This can lead to disruption of webhook-based integrations and potential denial of service or data integrity issues within affected environments. Confidentiality impact is not indicated.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to authenticated users with minimal privileges and monitor for suspicious activity related to webhook management. Avoid sharing credentials and consider additional application-layer access controls if possible.
