How to fix?

Upgrade Alpine:3.18 expat to version 2.6.0-r0 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream expat package and not the expat package as distributed by Alpine. See How to fix? for Alpine:3.18 relevant fixed versions and status.

libexpat through 2.5.0 allows a denial of service (resource consumption) because many full reparsings are required in the case of a large token for which multiple buffer fills are needed.
