What is CVE-2026-11325?

CVE-2026-11325 is cloudflare/pages-action is deprecated — migration required by September 18th, 2026. The supplied enrichment data classifies it as Remote Code Exec mapped to CWE-78 OS Command Injection; CWE-1104 CWE-1104.

Which versions are affected?

Affected product and version evidence is listed in the product table above. Current public advisories should be checked for exact version scope before patch targeting is finalized.

Is there active exploitation?

Active exploitation is not confirmed from current sources for CVE-2026-11325. If exploitation is not confirmed from current sources, teams should document that status and continue monitoring KEV, vendor, and telemetry updates.

No. CVE-2026-11325 is not listed in CISA KEV in the supplied enrichment data. KEV status should be monitored because it can change after initial disclosure or after exploitation becomes publicly confirmed.

Is there a public exploit?

2 public PoC repositories reported; 0 marked weaponized in current dataset. Public exploit or PoC availability should raise triage priority, especially for exposed or business-critical systems.

How can defenders detect it?

Start with web/proxy/WAF logs, application logs, network IDS/IPS, EDR process telemetry, host service logs where available. Look for vulnerability-class behavior, product errors, suspicious authentication events, exploit probes, and abnormal process activity based only on evidence that applies to the affected product.

How should teams prioritize it?

Prioritize CVE-2026-11325 using CVSS 8.8, EPSS 0%, KEV status, public PoC status, and asset exposure. Internet-facing, privileged, or business-critical deployments should be handled first.

Are workarounds available?

The supplied mitigation guidance says to apply vendor patches and restrict external exposure until fixed. Fixed-version evidence is listed in the mitigation section above.

Which threat actors are linked publicly?

No public threat actor linkage is confirmed from current sources. Do not attribute exploitation to a threat actor unless the source evidence explicitly supports that linkage.

What should be done in the next 24 hours?

Identify exposed assets running affected vendor/product/version combinations. Prioritize based on EPSS, PoC availability, and external exposure. Search available logs for exploit probes, errors, authentication anomalies, or suspicious child processes matching the vulnerability class. Open remediation tickets with affected assets, owners, evidence status, and detection coverage so decisions are traceable.

CVE-2026-11325

CVE-2026-11325 — cloudflare/pages-action is deprecated — migration required by September 18th, 2026

Description Cloudflare was recently notified by external researchers of vulnerabilities in this archived repository, including a remote code execution issue in `src/index.ts` reachable from certain GitHub Actions workflow configurations. Successful exploitation may expose workflow secrets such as CLOUDFLARE_API_TOKEN and GITHUB_TOKEN to an attacker. Because this repository has been deprecated since 2024, Cloudflare will not be issuing patches. To remediate this issue, we recommend migrating to `cloudflare/wrangler-action` immediately. Consumers who have already migrated are not affected. Sunset Date The cloudflare/pages-action repository will be removed on 2026-09-18. Consumers must complete migration before 18th September to avoid CI disruption. Affected Versions All published versions of cloudflare/pages-action, including consumers pinned to the v1 moving tag. Patched Versions None. This repository will not receive further updates, including security patches. Resolution / Migration Path Migrate all workflows using cloudflare/pages-action to `cloudflare/wrangler-action` before 2026-09-18. Refer to the wrangler-action README for the equivalent step configuration and migration guidance.

What should defenders know first?

CVE-2026-11325 is cloudflare/pages-action is deprecated — migration required by September 18th, 2026, a high vulnerability affecting https://github.com/cloudflare/pages-action from Cloudflare. The current evidence does not list it in CISA KEV, and the exploit status is: Active exploitation is not confirmed from current sources for CVE-2026-11325. Public exploit evidence is: 2 public PoC repositories reported; 0 marked weaponized in current dataset. The affected-version evidence is listed in the key facts and affected products tables. Defenders should first verify whether exposed or business-critical assets run those versions, then apply vendor patches or mitigations, restrict reachable attack surface, and preserve logs for detection review. CVSS 8.8 describes technical severity, while EPSS 0% helps estimate near-term exploit likelihood; neither replaces asset context. Unknown fields should remain explicit in tickets, and threat actor, IOC, victimology, or payload claims should not be added unless a cited source supports them. Monitor CISA KEV, vendor advisories, NVD changes, public PoC repositories, and internal telemetry for update triggers.
