This CVE has been marked Rejected in the CVE List. These CVEs are stored in the NVD, but do not show up in search results by default.
Current Description
Rejected reason: This CVE ID has been rejected by its CVE Numbering Authority (CNA). It was determined that the affected code path cannot be triggered through normal usage of Claude Code.
Anthropic Claude Code CLI and Claude Agent SDK contain an OS command injection vulnerability in the prompt editor invocation utility that allows attackers to execute arbitrary commands by crafting malicious file paths. Attackers can inject shell metacharacters such as $() or backtick expressions into file paths that are interpolated into shell commands executed via execSync. Although the file path is wrapped in double quotes, POSIX shell semantics (POSIX §2.2.3) do not prevent command substitution within double quotes, allowing injected expressions to be evaluated and resulting in arbitrary command execution with the privileges of the user running the CLI.
