CVE-2026-2264Network attack vector

Service account token exfiltration via unvalidated IntegrationRegion

Published May 26, 2026 · Updated May 26, 2026

SSRF in Google Apigee's SetIntegrationRequest policy allows remote attackers to exfiltrate service account access tokens. The policy fails to validate an IntegrationRegion flow variable and sends a request bearing the service account token to the attacker-controlled host it names. Exploitation requires an administrator to configure an API proxy so an attacker can control the flow variable used for IntegrationRegion.
