There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - markdown-it is a Markdown parser. Versions 14.1.1 and below contain a denial-of-service vulnerability when
    typographer: true is enabled, due to quadratic (O(n^2)) processing in the smartquotes rule. The issue
    stems from repeatedly modifying strings with replaceAt(), which performs O(n) slicing and concatenation
    per quote character. This can cause excessive CPU consumption when parsing quote-heavy, user-supplied
    markdown and may let attackers degrade or disrupt service availability. Although typographer is disabled
    by default, many production apps enable it for smart typography, making the issue relevant. This issue has
    been fixed in version 14.2.0. (CVE-2026-48988)
