CVE-2026-55411

ToolJet: Cross-tenant credential decryption (IDOR) in POST /api/data-sources/decrypt — any authenticated user can decrypt any organization's data-source secrets

Published Jun 25, 2026 CVSS 3.1 · 6.8 Medium EPSS < 1% KEV · Not listed
Description
ToolJet is the open-source foundation am AI-native platform for building and deploying internal tools, workflows and AI agents. Prior to 3.20.1780-lts, the authenticated endpoint POST /api/data-sources/decrypt returns the decrypted plaintext for any credential whose credential_id is supplied in the request body. Unlike every neighbouring data-source route, this handler is not protected by ValidateDataSourceGuard, does not receive the calling @User(), and the underlying CredentialsService.getValue() looks the credential up by id only, with no organization scoping. As a result, any authenticated user of any organization can decrypt the data-source secrets of any other organization by supplying that organization's credential_id — a cross-tenant confidentiality breach. This vulnerability is fixed in 3.20.1780-lts.
