Because interpolation happens before module policy enforcement at BaseModule.run, a workflow parameter can read host secrets such as cloud keys and send them out through an allowed module, reachable via the workflow API and the MCP agent surface.","solution":"Suggested fix in the source: apply the same policy to ${env.*} as to the env.get module by gating it behind an explicit allowlist of permitted variable names and denying by default when env.get is denied; alternatively, drop ${env.*} and require env values to be passed explicitly at workflow start.","labels":["security"],"sourceUrl":"https://github.com/advisories/GHSA-hr7p-wg7r-hg9m","publishedAt":"2026-07-30T14:47:01.000Z","cveId":"CVE-2026-67427","cweIds":null,"cvssScore":null,"cvssSeverity":"high","severity":"high","attackType":["other"],"issueType":"vulnerability","affectedPackages":["flyto-core@< 2.26.7 (fixed: 2.26.7)"],"affectedPackageNames":["flyto-core"],"affectedPackageRefs":["pypi:flyto-core"],"affectedVendors":[],"affectedVendorsRaw":["Flyto2 Core"],"classifierModel":"claude-haiku-5-5","classifierPromptVersion":"v4","summaryPromptVersion":"v2","headline":null,"headlinePromptVersion":null,"cvssVector":null,"attackVector":null,"attackComplexity":null,"privilegesRequired":null,"userInteraction":null,"exploitMaturity":"unknown","epssScore":0.00446,"epssCheckedAt":"2026-11-12T18:09:39.731Z","kevDateAdded":null,"advisoryAliases":["GHSA-hr7p-wg7r-hg9m"],"affectedPackagesSource":null,"affectedPackagesCheckedAt":null,"patchAvailable":true,"disclosureDate":"2026-07-30T14:47:01.000Z","fixReleasedAt":"2026-07-08T02:02:06.253Z","daysToFix":-22,"fixCheckedAt":"2026-10-29T21:32:32.296Z","capecIds":null,"crossRefCount":0,"attackSophistication":"trivial","impactType":["confidentiality"],"aiComponentTargeted":"agent","llmSpecific":false,"classifierConfidence":0.8,"researchCategory":null,"atlasIds":null,"fixes":[{"ecosystem":"pypi","name":"flyto-core","fixedVersion":"2.26.7","matchedVersion":"2.26.7","fixReleasedAt":"2026-07-08T02:02:06.253Z","daysToFix":-22,"match":"ecosystem","source":"registry","status":"found","checkedAt":"2026-10-29T21:32:32.145Z"}]}}
