## What is CVE-2026-55411?

CVE-2026-55411 is a medium-severity missing authorization vulnerability in ToolJet, published on 25 Jun 2026. It can only be exploited from the same machine or local network, with no action from the victim.

### Official 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.

Weakness: CWE-863 (Incorrect Authorization), CWE-639 (Authorization Bypass Through User-Controlled Key)

Check this codebase for CVE-2026-55411 and fix it if it is affected.

What it is: CVE-2026-55411 is a medium-severity missing authorization vulnerability in ToolJet, published on 25 Jun 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-55411 exists.

Affected product: ToolJet. No package-level version data is available, so check the vendor advisory linked from the reference page.

Task:
1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.
2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.
3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.
4. Run the tests and summarise what changed and why.
5. If nothing in the project is affected, say so and change nothing.
