CVE-2026-55412Public exploitNetwork attack vector

Cloud credential theft via DNS filter bypass

Published Jun 25, 2026 · Updated Jun 25, 2026

SSRF in ToolJet before 3.20.178-lts allows remote authenticated users to steal Azure managed identity tokens through RestAPI queries. The RestAPI data source passes server-side requests after comparing only the supplied hostname string with a private-address blocklist, without validating its resolved IP address. Any free-tier authenticated user who can create a RestAPI query can use a DNS name resolving to link-local Azure IMDS and obtain tokens scoped to accessible cloud resources; the protection is opt-in and disabled by default.
