How to fix?

Upgrade Echo:latest golang-golang-x-text to version 0.3.7-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream golang-golang-x-text package and not the golang-golang-x-text package as distributed by Echo. See How to fix? for Echo:latest relevant fixed versions and status.

golang.org/x/text/language in golang.org/x/text before 0.3.7 can panic with an out-of-bounds read during BCP 47 language tag parsing. Index calculation is mishandled. If parsing untrusted user input, this can be used as a vector for a denial-of-service attack.
