OSV identifies CVE-2023-34541 and lists 0.0.247 as the fixed package version.<\/p>\n<p>The practical concern is the trust boundary around a configuration loader. Treating a prompt or configuration as passive data is unsafe when its loading path can execute code. That lesson remains useful even though the advisory is old.<\/p>\n<p>For an inherited application, check the installed dependency and how prompt configurations enter the system. A minimum fix for this advisory is not a recommendation to deploy an obsolete release today.
