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.","epss":{"date":"2026-11-08","percentile":0.00372,"score":0.00089},"exploits":[{"kind":"exploit","source":"ADP: CISA-ADP","url":"https://github.com/berabuddies/agentflow/pull/18"}],"kev":null,"metrics":[{"score":4.8,"severity":"medium","source":"CNA: VulnCheck","vector":"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","version":"4.0"},{"score":4.4,"severity":"medium","source":"CNA: VulnCheck","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1794146928430,"publishedAt":1777485965772,"references":[{"source":"CNA: VulnCheck","tags":["issue-tracking","patch"],"url":"https://github.com/berabuddies/agentflow/pull/18"},{"source":"CNA: VulnCheck","tags":["patch"],"url":"https://github.com/berabuddies/agentflow/commit/1667fa3"},{"source":"CNA: VulnCheck","tags":["third-party-advisory"],"url":"https://www.vulncheck.com/advisories/agentflow-local-web-api-content-type-validation-bypass"},{"source":"ADP: CISA-ADP","tags":["exploit"],"url":"https://github.com/berabuddies/agentflow/pull/18"}],"remediation":[{"kind":"fix","source":"CNA: VulnCheck","text":"The reporting source identifies this reference as a patch.
