CVE-2026-71216Network attack vectorHinoki check available

Routing-key disclosure via cleartext PagerDuty POST

Published Sep 4, 2026 · Updated Sep 4, 2026

Cleartext transmission in the PagerDuty hook in Apache SkyWalking 9.6.0 through 10.4.0 allows attackers to read routing keys. The hook writes a JSON body containing the integration routing key to a plain HTTP socket before PagerDuty can return an HTTPS redirect. Exploitation requires visibility of the outbound network path and an enabled PagerDuty hook; a captured key authorizes forged PagerDuty events.
