Attackers can inject OS commands by passing untrusted arguments with the shell option, allowing arbitrary command execution with Deno process privileges.","cvssScore":8.1,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H","cwes":["CWE-78"],"vendors":[],"products":[],"references":[{"url":"https://github.com/denoland/deno","tags":[]},{"url":"https://github.com/denoland/deno/blob/0c071246a412575e07423263404a5d13e7ed6aa2/ext/node/polyfills/internal/child_process.ts#L1339","tags":[]},{"url":"https://github.com/denoland/deno/blob/0c071246a412575e07423263404a5d13e7ed6aa2/ext/node/polyfills/internal/child_process.ts#L1499","tags":[]},{"url":"https://github.com/denoland/deno/pull/36772","tags":[]},{"url":"https://www.vulncheck.com/advisories/deno-2.7.0-through-2.9.7-command-injection-via-node-child-process","tags":[]}],"exploitRefs":[{"url":"https://github.com/denoland/deno","tags":[]},{"url":"https://github.com/denoland/deno/blob/0c071246a412575e07423263404a5d13e7ed6aa2/ext/node/polyfills/internal/child_process.ts#L1339","tags":[]},{"url":"https://github.com/denoland/deno/blob/0c071246a412575e07423263404a5d13e7ed6aa2/ext/node/polyfills/internal/child_process.ts#L1499","tags":[]},{"url":"https://github.com/denoland/deno/pull/36772","tags":[]}],"hasPoc":true,"ai":{"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.","remediation":"Upgrade to Deno version 2.9.8 or later.","detection":"No reliable host or network indicator is derivable from the published description.","tags":["rce","shell-injection","deno"],"model":"qwen2.5:7b-instruct","analyzedAt":"2026-10-05T08:43:54.864Z"}}
