Tree-sitter-bash static parsing misses a command substitution hidden inside a single-quoted variable value, which the attacker re-expands with the ${var@P} prompt-transform operator so bash's promptvars feature runs it at runtime. Only the trailing allowlisted command is classified, so arbitrary commands run silently with the privileges of the agent's terminal session.","solution":"N/A -- no mitigation discussed in source.","labels":["security"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-109429","publishedAt":"2026-10-13T19:18:33.250Z","cveId":"CVE-2026-109429","cweIds":["CWE-436"],"cvssScore":"8.8","cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":null,"affectedPackageNames":null,"affectedPackageRefs":null,"affectedVendors":["Mistral"],"affectedVendorsRaw":["Mistral Vibe"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":"Mistral Vibe command permission gate bypass via hidden command substitution","headlinePromptVersion":"h1","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","attackVector":"network","attackComplexity":"low","privilegesRequired":"none","userInteraction":"required","exploitMaturity":"unknown","epssScore":0,"epssCheckedAt":"2026-10-14T06:09:04.445Z","kevDateAdded":null,"advisoryAliases":["GHSA-m84r-3mrm-j4p8"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":"2026-10-14T06:09:11.309Z","patchAvailable":null,"disclosureDate":"2026-10-13T19:18:33.250Z","capecIds":null,"crossRefCount":0,"attackSophistication":"moderate","impactType":["confidentiality","integrity","availability"],"aiComponentTargeted":"agent","llmSpecific":true,"classifierConfidence":0.9,"researchCategory":null,"atlasIds":null}}
