{"id":"CVE-2026-31995","summary":"OpenClaw 2026.1.21 \u003c 2026.2.19 - Command Injection via Windows Shell Fallback in Lobster Extension","details":"OpenClaw versions 2026.1.21 prior to 2026.2.19 contain a command injection vulnerability in the Lobster extension's Windows shell fallback mechanism that allows attackers to inject arbitrary commands through tool-provided arguments. When spawn failures trigger shell fallback with shell: true, attackers can exploit cmd.exe command interpretation to execute malicious commands by controlling workflow arguments.","aliases":["GHSA-fg3m-vhrr-8gj6"],"modified":"2026-08-12T03:51:17.023337473Z","published":"2026-03-19T01:00:53.469Z","database_specific":{"cna_assigner":"VulnCheck","cwe_ids":["CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31995.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/31xxx/CVE-2026-31995.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-fg3m-vhrr-8gj6"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-31995"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-command-injection-via-windows-shell-fallback-in-lobster-extension"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/ba7be018da354ea9f803ed356d20464df0437916"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openclaw/openclaw","events":[{"introduced":"80c1edc3ff43b3bd3b7b545eed79f303d992f7dc"},{"fixed":"2c05cbb43e48ebad03626d3125746fb1b9a8520f"},{"fixed":"ba7be018da354ea9f803ed356d20464df0437916"}],"database_specific":{"cpe":"cpe:2.3:a:openclaw:openclaw:*:*:*:*:*:node.js:*:*","extracted_events":[{"introduced":"2026.1.21"},{"fixed":"2026.2.19"}],"source":["CPE_RANGE","REFERENCES"]}}],"versions":["v2026.2.17","v2026.2.15-beta.1","v2026.2.14","v2026.2.13","v2026.2.12","v2026.2.9","v2026.2.6-3","v2026.2.6-2","v2026.2.6-1","v2026.2.6","v2026.2.3","v2026.2.2","v2026.2.1","v2026.1.30","v2026.1.29","v2026.1.24-1","v2026.1.24","v2026.1.23","v2026.1.22","v2026.1.21"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-31995.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:H/AT:N/PR:L/UI:N/VC:N/VI:H/VA:L/SC:N/SI:N/SA:N"}]}
