8.1 HIGHpublic exploit availablePublished 2026-09-30 · Updated 2026-10-02
AI risk analysis
- Summary
- The flaw allows command injection by improperly escaping shell arguments, enabling attackers to execute arbitrary commands with Deno process privileges.
- Exploitability
- Exploitation is moderately hard as it requires passing untrusted arguments with the shell option, but preconditions include the presence of untrusted input.
- Blast radius
- If exploited, this could lead to full system compromise, as the commands are executed with Deno process privileges.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to Deno version 2.9.8 or later.
