Attackers can craft cross-origin HTML pages with auto-submitting forms containing script payloads in the request body, which are served as text/html due to Go's content type detection, allowing the reflected script to execute in the podinfo origin context when victims visit the attacker's page.","published":"2026-05-14T12:37:40.408Z","modified":"2026-07-31T18:31:22.095521057Z","cvss":null,"epss":{"score":0.00195,"percentile":0.09363,"asOf":"2026-08-10"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/stefanprodan/podinfo","fixedVersion":"1.8.1-0.20260519111337-cbebb20fd485"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/43xxx/CVE-2026-43644.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-43644"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/podinfo-reflected-xss-via-echo-endpoint"},{"type":"REPORT","url":"https://github.com/stefanprodan/podinfo/issues/474"},{"type":"PACKAGE","url":"https://github.com/stefanprodan/podinfo"},{"type":"EVIDENCE","url":"https://github.com/Niccolo10/Security-Advisories/blob/main/CVE-2026-43644/cve-2026-43644.md"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-31T18:31:22.095521057Z"}}
