How to fix?

Upgrade Alpine:3.14 libxslt to version 1.1.33-r1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream libxslt package and not the libxslt package as distributed by Alpine. See How to fix? for Alpine:3.14 relevant fixed versions and status.

libxslt through 1.1.33 allows bypass of a protection mechanism because callers of xsltCheckRead and xsltCheckWrite permit access even upon receiving a -1 error code. xsltCheckRead can return -1 for a crafted URL that is not actually invalid and is subsequently loaded.
