CVE-2026-71365 Red Hat CVE debrief

AI-assisted PatchSiren debrief based on the supplied source corpus. The CVE record was published on 2026-08-18T16:18:16.157Z and has not been modified since then. The vulnerability is a server-side request forgery (SSRF) in AWX's webhook status callback mechanism. An admin user can forge a signed GitHub webhook payload with an arbitrary statuses_url, causing AWX to POST status updates to an attacker-controlled or internal URL, resulting in credential leakage. This occurs when processing GitHub pull request webhooks, allowing an attacker to read the template's webhook signing key and forge a signed payload. Affected operators should review webhook configurations, and security teams should monitor for suspicious activity. Vulnerability management teams should prioritize patching, and platform administrators should restrict access to AWX's webhook status callback mechanism. Evidence is based on limited information from the NVD and Red Hat sources. Further investigation is recommended to fully understand the vulnerability's impact, including reviewing AWX's webhook status callback mechanism, GitHub pull request webhooks, and potential credential leakage scenarios. Defenders should verify affected AWX deployments, review webhook configurations, and monitor for suspicious activity.

Who should care

AWX administrators, Red Hat users, and organizations using AWX should be aware of this vulnerability and take steps to mitigate it. Affected operators should review webhook configurations, and security teams should monitor for suspicious activity. Vulnerability management teams should prioritize patching, and platform administrators should restrict access to AWX's webhook status callback mechanism.

Technical summary

A server-side request forgery (SSRF) vulnerability was found in AWX's webhook status callback mechanism. An admin user can forge a signed GitHub webhook payload with an arbitrary statuses_url, causing AWX to POST status updates to an attacker-controlled or internal URL, resulting in credential leakage. The vulnerability is triggered when processing GitHub pull request webhooks, allowing an attacker to read the template's webhook signing key and forge a signed payload.

Defensive priority

Organizations using AWX should prioritize patching this vulnerability to prevent potential credential leakage.

Recommended defensive actions

Review and apply patches from Red Hat to fix the SSRF vulnerability
Restrict access to AWX's webhook status callback mechanism
Monitor for suspicious activity related to GitHub pull request webhooks
Review compensating controls for exposed systems while remediation is scheduled and verified
Check relevant monitoring, detection, and logs for exposed assets that need extra review
Track exceptions, retest remediated assets, and close the item only after evidence is documented
Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up

Evidence notes

Evidence is based on limited information from the NVD and Red Hat sources. Further investigation is recommended to fully understand the vulnerability's impact, including reviewing AWX's webhook status callback mechanism, GitHub pull request webhooks, and potential credential leakage scenarios. Defenders should verify affected AWX deployments, review webhook configurations, and monitor for suspicious activity.
