{"id":"CVE-2026-67427","summary":"Flyto2 Core: ${env.VAR} interpolation reads any env secret despite env.get being denylisted","details":"Flyto2 Core is an execution kernel for automation and AI-agent workflows. Prior to 2.26.6, the workflow engine variable resolver expands ${env.VAR} for any host environment variable without an allowlist or capability policy check, allowing a workflow parameter to bypass the default capability policy denylist for env.get and env.load_dotenv and exfiltrate secrets through allowed modules. This issue is fixed in version 2.26.6.","aliases":["GHSA-hr7p-wg7r-hg9m"],"modified":"2026-07-30T04:03:38.689702422Z","published":"2026-07-29T18:45:47.908Z","database_specific":{"cwe_ids":["CWE-522","CWE-668","CWE-693"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67427.json","cna_assigner":"GitHub_M"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67427.json"},{"type":"FIX","url":"https://github.com/flytohub/flyto-core/commit/d5f89d71303e3c1e6418d347c5c55fcd173cc8cc"},{"type":"WEB","url":"https://github.com/flytohub/flyto-core/releases/tag/v2.26.6"},{"type":"ADVISORY","url":"https://github.com/flytohub/flyto-core/security/advisories/GHSA-hr7p-wg7r-hg9m"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67427"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/flytohub/flyto-core","events":[{"introduced":"0"},{"fixed":"2471c6e774102fcca21c61eb66cae057c0f0cecf"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"2.26.6"}],"source":"AFFECTED_FIELD"}}],"versions":["v2.26.4","v2.26.3","v2.26.0","v2.25.27","v2.17.6","v2.16.3","v2.5.0","v2.2.2"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-67427.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:N/A:N"}]}
