What is CVE-2026-45760?

CVE-2026-45760 is an server-side request forgery (SSRF) flaw in Apache Camel K. The product makes server-side HTTP requests to attacker-controlled URLs, exposing internal services and cloud metadata endpoints. Vendor description: (Externally Controlled Reference to a Resource in Another Sphere), (Authorization Bypass Through User-Controlled Key) vulnerability in Apache Camel K. Authorized users in a Kubernetes namespace can create a Build resource, controlling the Pod generation in a namespace of their choice, including the operator namespace.

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 Apache Camel K 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.

Run the project-specific version command (for example httpd -v, tomcat version, or check pom.xml / package metadata) and compare against the advisory.

How to fix CVE-2026-45760

  1. Read the vendor advisory in full: https://camel.apache.org/security/CVE-2026-45760.html
  2. Upgrade Apache Camel K 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).

Patch Kubernetes / container workload


# CVE-2026-45760 affects Apache Camel K 2.0.0 < 2.8.1. Fixed in 2.8.1.
# Vendor advisory: https://camel.apache.org/security/CVE-2026-45760.html

# 1. Roll the affected component to the patched image.
kubectl set image deployment/<deployment-name> apache-camel-k=<registry>/apache-camel-k:2.8.1

# 2. Watch the rollout complete.
kubectl rollout status deployment/<deployment-name>

# 3. Confirm pods are running the new image.
kubectl get pods -o jsonpath='{.items[*].spec.containers[*].image}'

# 4. For Helm-managed releases.
helm upgrade <release-name> <chart> --set image.tag=2.8.1

Verify the fix landed


# CVE-2026-45760 verification checklist.

# 1. Confirm the running version matches 2.8.1 (replace the version probe with
#    the platform-specific command shown above).

# 2. Re-scan the host with your vulnerability scanner (Nessus, Qualys, Tenable,
#    OpenVAS, Wazuh). The scanner must no longer flag CVE-2026-45760.

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

# 4. Cross-check the running build against the vendor advisory:
#    https://camel.apache.org/security/CVE-2026-45760.html

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-2026-45760 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-2026-45760?

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 Apache Camel K 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.
