## What is CVE-2026-77226?

CVE-2026-77226 is a critical missing authorization vulnerability in Camunda 7, published on 5 Oct 2026. An attacker can exploit it over the internet without logging in, with no action from the victim.

### Official description

Camunda 7.24.0 before 7.24.15 contains an incorrect authorization vulnerability in the Admin web application's first-run setup endpoint, where SetupResource incorrectly determines setup availability by counting only direct members of the camunda-admin group rather than recognizing all configured administrators. An unauthenticated remote attacker can exploit this logic flaw to call the setup user-create endpoint and create a new administrator account when the camunda-admin group is empty but the system is fully administered, resulting in account takeover and potential process deployment or script execution as the engine's service user.

Weakness: CWE-863 (Incorrect Authorization)

Affected product: Camunda 7. 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.
