## What is CVE-2026-72870?

CVE-2026-72870 is a high-severity command injection vulnerability in dokploy, published on 10 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.

### Official description

Dokploy is a free, self-hostable Platform as a Service (PaaS). Prior to 0.29.13, the buildRemoteDocker() function in packages/server/src/utils/providers/docker.ts interpolates the application-controlled dockerImage value directly into a docker pull shell command. An authenticated user with project access can set a crafted dockerImage through application.update and trigger application.deploy, causing execAsync() to execute arbitrary operating-system commands as the Dokploy server process. This issue is fixed in version 0.29.13.

Weakness: CWE-78 (Improper Neutralization of Special Elements used in an OS Command)

What it is: CVE-2026-72870 is a high-severity command injection vulnerability in dokploy, published on 10 Aug 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Exploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-72870 exists.

Affected product: dokploy. 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.
