{"id":"CVE-2026-67424","summary":"Flyto2 Core: Guarded HTTP modules follow redirects into internal space without per-hop SSRF revalidation","details":"Flyto2 Core is an execution kernel for automation and AI-agent workflows. Prior to 2.26.7, the HTTP modules http.get, http.request, and http.batch in src/core/modules/atomic/http/get.py, src/core/modules/atomic/http/request.py, and src/core/modules/atomic/http/batch.py validate only the initial URL, then follow redirects with allow_redirects=True and without per-hop Location revalidation, allowing a public URL to redirect into internal address space and return the internal response body. This issue is fixed in version 2.26.7.","aliases":["GHSA-c9hr-64h3-gxpc","PYSEC-2026-3569"],"modified":"2026-08-12T03:51:34.694919984Z","published":"2026-07-29T18:32:00.887Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67424.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-918"]},"references":[{"type":"WEB","url":"https://github.com/flytohub/flyto-core/releases/tag/v2.26.7"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/67xxx/CVE-2026-67424.json"},{"type":"ADVISORY","url":"https://github.com/flytohub/flyto-core/security/advisories/GHSA-c9hr-64h3-gxpc"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67424"},{"type":"FIX","url":"https://github.com/flytohub/flyto-core/commit/0a0a528520ec18f5a21f1ddf858a71cc1edfb6e9"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/flytohub/flyto-core","events":[{"introduced":"0"},{"fixed":"0a0a528520ec18f5a21f1ddf858a71cc1edfb6e9"},{"fixed":"9449def37907190798b5d677b716526b09ae7302"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"2.26.7"}]}}],"versions":["v2.26.6","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-2026-67424.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:N"}]}
