## What is CVE-2026-66082?

CVE-2026-66082 is a medium-severity missing authorization vulnerability in Apache DolphinScheduler, published on 8 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

An authorization bypass vulnerability in Apache DolphinScheduler allows authenticated users to perform unauthorized operations on workflow schedules, workflow definitions, and task instances in other projects.

The affected endpoints check permissions against the supplied projectCode but fail to verify that the target resource belongs to that project. An authenticated user with the required permissions in one project can supply that project's code together with a resource identifier from another project, bypassing the target project's access restrictions.

The affected endpoints include:

  *  

POST /projects/{projectCode}/schedules/{id}/online and /offline: Activate or deactivate workflow schedules in another project.

  *  

POST /projects/{projectCode}/workflow-definition/{code}/release: Change the ONLINE/OFFLINE state of workflow definitions in another project.

Successful exploitation allows users to alter workflow availability and interfere with task execution in projects they are not authorized to access.

This issue affects Apache DolphinScheduler: before 3.4.3.

Users are recommended to upgrade to version 3.4.3, which fixes the issue.

Weakness: CWE-863 (Incorrect Authorization)

Check this codebase for CVE-2026-66082 and fix it if it is affected.

What it is: CVE-2026-66082 is a medium-severity missing authorization vulnerability in Apache DolphinScheduler, published on 8 Oct 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-2026-66082 in the wild and no public exploit code.

Affected product: Apache DolphinScheduler. 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.
