Overview

CVE-2026-68558 is a high-severity vulnerability. It was published on August 19, 2026 and has a CVSS 3.1 base score of 8.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 8.5, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

Wekan is open source kanban built with Meteor. From 8.36 until 9.74, the outgoing webhook Integration URL validator in models/integrations.js checked only the literal URL.hostname against regular expressions, so DNS names such as 169-254-169-254.nip.io passed that first-line check. The delivery path's fetchSafe guard already blocked the reported IPv4 destination, but its separate IPv4-only resolver and duplicated blocklist created inconsistent all-address-family enforcement and drift risk between input-time and connection-time validation. Version 9.74 makes server/lib/ssrfGuard.js resolve all addresses with `dns.lookup({ all: true })`, validate every result through the shared isIpBlocked logic, pin the connection, and block redirects. This issue is fixed in version 9.74.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
