What is CVE-2026-7471?

CVE-2026-7471 is an server-side request forgery (SSRF) flaw in GitLab. The product makes server-side HTTP requests to attacker-controlled URLs, exposing internal services and cloud metadata endpoints. Vendor description: GitLab has remediated an issue in GitLab EE affecting all versions from 18.8 before 18.9.7, 18.10 before 18.10.6, and 18.11 before 18.11.3 that could have allowed an authenticated user with control of a virtual registry upstream to make requests to internal hosts due to improper validation.

Why this CVE matters

Server-side request forgery routinely chains into cloud-metadata theft, internal service enumeration, and credential exfiltration. In cloud-hosted deployments the impact is often more severe than on-prem because of the metadata service exposure.

For deployments of GitLab 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 GitLab'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-2026-7471

  1. Read the vendor advisory in full: https://gitlab.com/gitlab-org/gitlab/-/work_items/594196
  2. Upgrade GitLab 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).

Linux package upgrade

The vendor advisory (https://gitlab.com/gitlab-org/gitlab/-/work_items/594196) names the patched build as the build named in the vendor advisory (https://gitlab.com/gitlab-org/gitlab/-/work_items/594196).


# Ubuntu / Debian
sudo apt-get update
sudo apt-get install --only-upgrade git
dpkg -s git | grep -i version

# RHEL / Rocky / AlmaLinux / Fedora
sudo dnf upgrade --refresh git -y
rpm -q git

# openSUSE
sudo zypper refresh && sudo zypper update git

# Restart the service that loads the patched binary
sudo systemctl restart git 2>/dev/null || true
sudo systemctl status git --no-pager 2>/dev/null || true


# Vendor advisory: https://gitlab.com/gitlab-org/gitlab/-/work_items/594196
# Container deployments: rebuild with the patched package layer, then roll the workload.
docker pull <your-registry>/git:<patched-tag>
docker stop <app> && docker rm <app>
docker run -d --name <app> <your-registry>/git:<patched-tag>

# Kubernetes
kubectl set image deployment/<deployment-name> git=<your-registry>/git:<patched-tag>
kubectl rollout status deployment/<deployment-name>

Verify the fix landed


# Vendor advisory: https://gitlab.com/gitlab-org/gitlab/-/work_items/594196
# 1. Compare the running version against the fixed build named above.
#    (Replace the version probe with the platform-specific command from the block above.)

# 2. Re-scan with your vulnerability scanner (Nessus, Qualys, Tenable, OpenVAS).
#    The scanner should no longer flag this CVE on the patched target.

# 3. Inspect recent service / kernel logs for crash loops or rollback events.
journalctl -u <service> --since "10 minutes ago"
dmesg --since "10 minutes ago"

If you cannot patch immediately

Block outbound network access from the affected service to internal subnets and cloud metadata endpoints (e.g. 169.254.169.254). Apply the patched build.

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 unusually long URI paths containing traversal sequences, unexpectedly large responses from the affected endpoint, and outbound requests from the application to internal addresses or cloud-metadata endpoints. Treat any sensitive file the bug could disclose as exposed.

Frequently asked questions

Is CVE-2026-7471 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-2026-7471?

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 GitLab 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.
