{"id":"CVE-2026-42435","summary":"OpenClaw 2026.2.22 \u003c 2026.4.12 - Shell-Wrapper Detection Bypass via Environment Variable Assignment Injection","details":"OpenClaw versions from 2026.2.22 before 2026.4.12 contain an insufficient shell-wrapper detection vulnerability allowing attackers to inject environment variable assignments at the argv level. Attackers can bypass exec preflight handling to manipulate high-risk shell variables like SHELLOPTS and PS4, affecting execution semantics and security controls.","aliases":["GHSA-j6c7-3h5x-99g9"],"modified":"2026-07-08T08:13:19.420897621Z","published":"2026-05-05T11:24:54.597Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42435.json","cwe_ids":["CWE-184"],"cna_assigner":"VulnCheck"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/42xxx/CVE-2026-42435.json"},{"type":"ADVISORY","url":"https://github.com/openclaw/openclaw/security/advisories/GHSA-j6c7-3h5x-99g9"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-42435"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/openclaw-shell-wrapper-detection-bypass-via-environment-variable-assignment-injection"},{"type":"FIX","url":"https://github.com/openclaw/openclaw/commit/8f8492d172f4c5b4fd7dd9a47855ed620c8770ab"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openclaw/openclaw","events":[{"introduced":"a54dc7fe80fc02e2a02e6901668a468fcb0cf8b4"},{"fixed":"1c0672b74f66038fd4ee76fbf1c21715887149d8"},{"fixed":"8f8492d172f4c5b4fd7dd9a47855ed620c8770ab"}],"database_specific":{"source":["DESCRIPTION","REFERENCES"],"extracted_events":[{"introduced":"2026.2.22"},{"fixed":"2026.4.12"}]}}],"versions":["v2026.4.12-beta.1","v2026.4.11","v2026.4.11-beta.1","v2026.4.10","v2026.4.9","v2026.4.9-beta.1","v2026.4.8","v2026.4.7-1","v2026.4.7","v2026.4.5","v2026.4.2","v2026.4.1","v2026.4.1-beta.1","v2026.3.31","v2026.3.31-beta.1","v2026.3.28","v2026.3.28-beta.1","v2026.3.24","v2026.3.24-beta.2","v2026.3.24-beta.1","v2026.3.23-2","v2026.3.23","v2026.3.23-beta.1","v2026.3.22","v2026.3.22-beta.1","v2026.3.13-1","v2026.3.13","v2026.3.12","v2026.3.11","v2026.3.11-beta.1","v2026.3.8","v2026.3.8-beta.1","v2026.3.7","v2026.3.7-beta.1","v2026.3.2-beta.1","v2026.3.2","v2026.3.1","v2026.2.26","v2026.2.26-beta.1","v2026.2.25","v2026.2.25-beta.1","v2026.2.24","v2026.2.24-beta.1","v2026.2.23","v2026.2.23-beta.1","v2026.2.22"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-42435.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N"}]}
