CVE-2026-30846Network attack vector

Unauthenticated webhook token disclosure via unguarded publication

Published Mar 6, 2026 · Updated Mar 6, 2026

Information disclosure in WeKan 8.31.0 through 8.33 allows remote attackers to retrieve global webhook URLs and tokens via DDP. The globalwebhooks publication queries every global integration without checking the DDP user or administrator status and returns URL and token fields. No account or user interaction is required; exposed credentials permit unauthorized use of configured external-service webhooks.
