Type (CWE)CWE-798: Use of Hard-coded Credentials

What is CVE-2026-24840?

CVE-2026-24840 is a hard-coded credentials issue in dokploy. The product ships with a built-in account or key that anyone with a copy of the software can recover and use to log in. Vendor description: Dokploy is a free, self-hostable Platform as a Service (PaaS). In versions prior to 0.26.6, a hardcoded credential in the provided installation script (located at https://dokploy.com/install.sh, line 154) uses a hardcoded password when creating the database container.

Why this CVE matters

Hard-coded credentials are the lowest-effort path to compromise. Once the secret is reverse-engineered out of the firmware or source, every deployment of the same version is reachable by anyone with the advisory text.

For deployments of dokploy that have been exposed to the public internet during the disclosure window, the operating assumption should be that scanning has already happened. Even where exploitation has not been publicly observed, scanning for the vulnerable fingerprint is cheap and routine. Patching closes the door; log review and credential rotation close out the rest of the response.

Am I affected?

You are affected if your installation matches any of these version ranges:

Check your installed version against the list above. If you cannot determine the version, treat the system as affected and follow the upgrade path below.

Open dokploy's About dialog or run the vendor-documented version-check command. Compare the result against the affected ranges in the advisory.

How to fix CVE-2026-24840

  1. Read the vendor advisory in full: https://github.com/Dokploy/dokploy/security/advisories/GHSA-jr65-3j3w-gjmc
  2. Upgrade dokploy to the patched build listed in the vendor advisory.
  3. Back up the configuration (and database, where applicable) before upgrading.
  4. Apply the patch in a maintenance window. For HA pairs, upgrade the standby node first, fail over, then upgrade the former primary.
  5. Restart the affected service so the patched binary loads, then verify the new version (see verification section).

If you cannot patch immediately

No official workaround exists beyond restricting network exposure to the affected component. Apply the vendor patch as the primary remediation.

How to verify the fix worked

If your installation was internet-reachable during the disclosure window, treat log review as part of the remediation rather than an optional follow-up. Look for unexpected administrator accounts in dokploy, scheduled tasks or cron jobs you did not create, new files in web-accessible directories, and outbound connections to addresses not in your baseline. Suspicious requests to the vulnerable endpoint immediately followed by successful 200-class responses with unusually large bodies are a strong indicator of exploitation.

Frequently asked questions

Is CVE-2026-24840 being exploited in the wild?

Public exploitation has not been confirmed by CISA at the time of writing. Treat the patch as time-sensitive anyway; reports often lag actual abuse.

Will a WAF or IDS rule fully mitigate CVE-2026-24840?

No. Network-layer filters can reduce noise and slow opportunistic scanners, but they will not stop a determined attacker. The vendor patch is the only durable fix.

How long should I plan for the upgrade?

Typical vendor-documented upgrade windows for dokploy run from a few minutes to under an hour depending on cluster size. Test in a staging environment first and follow the vendor's documented HA upgrade order.
