{"id":"CVE-2026-55249","summary":"@rtk-ai/rtk-rewrite: OpenClaw Rewrite Plugin Command Injection via execSync Template String","details":"@rtk-ai/rtk-rewrite transparently rewrites shell commands executed via OpenClaw's exec tool to their RTK equivalents. In 1.0.0, the @rtk-ai/rtk-rewrite OpenClaw plugin passes attacker-controlled input directly into a shell-backed execSync() template string without shell-safe escaping. JSON.stringify() wraps the value in double quotes and escapes inner double-quotes and backslashes, but leaves $() and backtick shell metacharacters untouched. Because execSync delegates execution to /bin/sh -c, the shell expands $(...) substitutions even inside double-quoted strings, causing the injected subcommand to execute before rtk is invoked. An attacker who can influence the exec tool's command parameter (e.g., via an LLM agent prompt or gateway/tool-call input) achieves arbitrary OS command execution with the privileges of the plugin/gateway process.","aliases":["GHSA-fqgj-m2gp-mr3q"],"modified":"2026-10-21T02:58:37.157054641Z","published":"2026-06-23T18:33:46.014Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55249.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-78"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55249.json"},{"type":"ADVISORY","url":"https://github.com/rtk-ai/rtk/security/advisories/GHSA-fqgj-m2gp-mr3q"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55249"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/rtk-ai/rtk","events":[{"introduced":"01f819c41da43698f5aedf2a8d730f716779009a"},{"last_affected":"01f819c41da43698f5aedf2a8d730f716779009a"}],"database_specific":{"extracted_events":[{"source":"AFFECTED_FIELD","strategy":"StandaloneSingleVersion","range":[{"introduced":"1.0.0"},{"last_affected":"1.0.0"}]},{"cpe":"cpe:2.3:a:rtkai:rtk-rewrite:1.0.0:*:*:*:*:rust:*:*","range":[{"introduced":"1.0.0"},{"last_affected":"1.0.0"}],"source":"CPE_STRING"}]}}],"versions":["1.0.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55249.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:L/A:N"}]}
