How to fix?

Upgrade Chainguard ory-kratos to version 26.2.0-r25 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream ory-kratos package and not the ory-kratos package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

Multiple ECH outer extension references are not permitted under RFC 9849; previously, a client could send a well-crafted packet that could trigger memory exhaustion in the server process by specifying multiple references. We now reject these as malformed and curb the memory amplification vector as a result.
