CVE-2026-73411: CWE-116: Improper Encoding or Escaping of Output in ericcornelissen shescape
Shescape is a simple shell escape library for JavaScript. Prior to 2.1.14 and 3.0.1, getEscapeFunction in src/internal/unix/dash.js fails to escape ~ after : or = when applications use the escape or escapeAll APIs on Unix with shell set to dash, or with shell set to true when Dash is the default, and interpolate the result into an assignment prefixed to a command. An attacker who controls the input can supply a value such as :~ to disclose the home-directory path and may change the location on which the command operates. This issue is fixed in versions 2.1.14 and 3.0.1.
