MEDIUM 6.1EPSS 8.00%

Does this matter?

Lower severity and a low EPSS score (8.00%). Track it; it rarely justifies an emergency change on its own.

Description

The npm package ansi_up converts ANSI escape codes into HTML. In ansi_up v4, ANSI escape codes can be used to create HTML hyperlinks. Due to insufficient URL sanitization, this feature is affected by a cross-site scripting (XSS) vulnerability. This issue is fixed in v5.0.0.
