Detailsinfo

A vulnerability was found in ToolJet up to 3.20.178-lt/169.254.169.254.nip.io and classified as critical. Affected by this issue is an unknown part of the component RestAPI Data Source. The manipulation with an unknown input leads to a server-side request forgery vulnerability. Using CWE to declare the problem leads to CWE-918.

Impacted is confidentiality, integrity, and availability. CVE summarizes:

ToolJet is the open-source foundation am AI-native platform for building and deploying internal tools, workflows and AI agents. Prior to 3.20.178-lts, there's an SSRF in the RestAPI data source component. The RestAPI data source executes HTTP requests server-side, and its private IP filter only checks the hostname string — not the resolved IP. DNS names like 169.254.169.254.nip.io resolve to the Azure IMDS link-local address and bypass the filter entirely. This allows any authenticated user (free tier) to steal Azure managed identity tokens for the AKS production cluster. This vulnerability is fixed in 3.20.178-lts.

The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-55412 since 06/16/2026. The exploitation is known to be easy. The attack may be launched remotely. There are neither technical details nor an exploit publicly available.

Upgrading to version 3.20.178-lts eliminates this vulnerability.
