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.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N","score":5.1},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N","score":6.1},"cwes":["CWE-79"],"references":["https://github.com/Niccolo10/Security-Advisories/blob/main/CVE-2026-43644/cve-2026-43644.md","https://github.com/stefanprodan/podinfo/issues/474","https://www.vulncheck.com/advisories/podinfo-reflected-xss-via-echo-endpoint"],"products":["stefanprodan:podinfo"],"source":"nvd","synced_at":"2026-10-19T22:35:16.954578616+00:00"},"epss":{"cve":"CVE-2026-43644","score":0.00195,"percentile":0.09072,"date":"2026-10-25"},"kev":null,"osv":[{"id":"GHSA-q23m-vm9r-5745","url":"https://osv.dev/vulnerability/GHSA-q23m-vm9r-5745","summary":"podinfo: cross-site scripting vulnerability in the /echo and /api/echo endpoints","modified":"2026-06-25T23:11:09.848977079Z","packages":[{"ecosystem":"Go","name":"github.com/stefanprodan/podinfo","purl":"pkg:golang/github.com/stefanprodan/podinfo","ranges":["<1.8.1-0.20260519111337-cbebb20fd485"],"fixed":["1.8.1-0.20260519111337-cbebb20fd485"]}]},{"id":"GO-2026-5560","url":"https://osv.dev/vulnerability/GO-2026-5560","summary":"podinfo: cross-site scripting vulnerability in the /echo and /api/echo endpoints in github.com/stefanprodan/podinfo","modified":"2026-06-25T23:01:30.130860176Z","packages":[{"ecosystem":"Go","name":"github.com/stefanprodan/podinfo","purl":"pkg:golang/github.com/stefanprodan/podinfo","ranges":["<1.8.1-0.20260519111337-cbebb20fd485"],"fixed":["1.8.1-0.20260519111337-cbebb20fd485"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
