Technical Analysis

The vulnerability CVE-2026-50875 affects Deck9 Input v2.0.1 and involves improper access control on the /{form}/webhooks/{webhook} endpoint. Authenticated attackers can exploit this flaw to arbitrarily modify or delete webhooks of other tenants by sending crafted requests. This indicates a failure in enforcing tenant isolation and authorization checks on webhook management operations. No information about available patches or fixes has been provided, and there are no known exploits in the wild at this time.

Potential Impact

An authenticated attacker can bypass access controls to alter or remove webhook configurations of other tenants, potentially disrupting integrations or causing unauthorized changes in the affected system. This could lead to denial of service or manipulation of webhook-triggered workflows for other tenants. The impact is limited to authenticated users but affects tenant isolation and data integrity.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict access to the vulnerable endpoint to trusted users only and monitor for suspicious activity related to webhook modifications. Implement additional access control checks at the application or network level if possible.
