NVD Description

Note: Versions mentioned in the description apply only to the upstream vitess-22 package and not the vitess-22 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

Impact:

A bad regular expression is generated any time you have multiple sequential optional groups (curly brace syntax), such as {a}{b}{c}:z. The generated regex grows exponentially with the number of groups, causing denial of service.

Patches:

Fixed in version 8.4.0.

Workarounds:

Limit the number of sequential optional groups in route patterns. Avoid passing user-controlled input as route patterns.
