{"id":"CVE-2026-7439","summary":"AgentFlow Local Web API Content-Type Validation Bypass","details":"AgentFlow's local web API accepts non-JSON content types on POST /api/runs and POST /api/runs/validate endpoints without enforcing application/json validation, allowing attackers to bypass trust-boundary enforcement on sensitive operations. Attackers can exploit this content-type validation weakness through browser-driven or local cross-origin requests to abuse the localhost API and enable attack chains against the local control plane.","modified":"2026-07-14T04:02:32.970415261Z","published":"2026-04-29T18:06:05.772Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/7xxx/CVE-2026-7439.json","unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"fixed":"1667fa3"}]}],"cna_assigner":"VulnCheck","cwe_ids":["CWE-346"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/7xxx/CVE-2026-7439.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-7439"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/agentflow-local-web-api-content-type-validation-bypass"},{"type":"REPORT","url":"https://github.com/berabuddies/agentflow/pull/18"},{"type":"FIX","url":"https://github.com/berabuddies/agentflow/commit/1667fa3"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/berabuddies/agentflow","events":[{"introduced":"0"},{"fixed":"1667fa3"}],"database_specific":{"source":"REFERENCES"}}],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-7439.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:L/AC:L/AT:N/PR:N/UI:P/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N"}]}
