## What is CVE-2026-94455?

CVE-2026-94455 is a high-severity missing authorization vulnerability in GitroomHQ postiz-app, published on 22 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

An HTTP endpoint intended for provisioning enterprise and reseller organisations is reachable without any session. The authentication middleware is bound only to an explicit list of controllers, and the enterprise controller is not on that list, so no authentication runs for these routes.

The endpoint's only check is that the request body carries a token bearing a valid signature from the instance secret. It does not check what that token was issued for. Login tokens are signed with the same secret and carry no purpose, audience or expiry claim, so an ordinary user's own session token satisfies the check.

Presented with such a token, the endpoint creates a new organisation holding the highest subscription tier, flagged as lifetime and with a channel allowance far above any sold plan, creates an organisation-owner account alongside it, and returns the new organisation's API key in the response body. That key is immediately valid against the public API.

Weakness: CWE-770 (Allocation of Resources Without Limits or Throttling), CWE-345 (Insufficient Verification of Data Authenticity), CWE-306 (Missing Authentication for Critical Functionality), CWE-1390 (Weak Authentication)

Check this codebase for CVE-2026-94455 and fix it if it is affected.

What it is: CVE-2026-94455 is a high-severity missing authorization vulnerability in GitroomHQ postiz-app, published on 22 Sep 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: There is no known exploitation of CVE-2026-94455 in the wild and no public exploit code.

Affected product: GitroomHQ postiz-app. 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.
