{"id":"CVE-2026-43991","summary":"JunoClaw: plugin-shell shell-injection bypass via substring blocklist","details":"JunoClaw is an agentic AI platform built on Juno Network. Prior to 0.x.y-security-1, substring-based blocklist in plugin-shell's command-safety check could be bypassed by adversarial argument constructions, allowing unauthorized command execution on the host when combined with the companion advisory. Pre-patch, the check was applied to the raw command string rather than the parsed first token. This vulnerability is fixed in 0.x.y-security-1.","aliases":["GHSA-fvq5-79h6-952c"],"modified":"2026-07-15T01:49:04.813767794Z","published":"2026-05-12T16:19:54.198Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-184","CWE-78"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43991.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43991.json"},{"type":"ADVISORY","url":"https://github.com/Dragonmonk111/junoclaw/security/advisories/GHSA-fvq5-79h6-952c"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43991"},{"type":"FIX","url":"https://github.com/Dragonmonk111/junoclaw/commit/2bc54f6"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dragonmonk111/junoclaw","events":[{"introduced":"0"},{"fixed":"2bc54f6"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"v0.x.y-security-1"}]}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-43991.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
