{"id":"CVE-2026-35198","summary":"HeyForm vulnerable to stored XSS via form field titles","details":"HeyForm is an open-source form builder. Prior to version 3.0.0-rc.7, a stored cross-site scripting (XSS) vulnerability in the form builder allows a low-privileged team member to inject malicious JavaScript that executes when a team owner views the form, leading to complete account takeover through privilege escalation. Version 3.0.0-rc.7 contains a patch for the issue.","aliases":["GHSA-chmm-jqpm-3pwx"],"modified":"2026-08-23T03:42:58.437004513Z","published":"2026-07-20T15:47:21.255Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-79"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35198.json"},"references":[{"type":"WEB","url":"https://vokecyber.com/research/cve-2026-35198-heyform-stored-xss"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/35xxx/CVE-2026-35198.json"},{"type":"ADVISORY","url":"https://github.com/heyform/heyform/security/advisories/GHSA-chmm-jqpm-3pwx"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-35198"},{"type":"FIX","url":"https://github.com/heyform/heyform/commit/cc97d27a57ae400fec23abf5dcf6f9533c3b5db3"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/heyform/heyform","events":[{"introduced":"0"},{"fixed":"cc97d27a57ae400fec23abf5dcf6f9533c3b5db3"}],"database_specific":{"source":["AFFECTED_FIELD","REFERENCES"],"extracted_events":[{"introduced":"0"},{"fixed":"3.0.0-rc.7"}]}}],"versions":["v3.0.0-rc.6","v3.0.0-rc.5","v3.0.0-rc.4","v3.0.0-rc.3","v3.0.0-rc.2","v3.0.0-rc.1","v3.0.0-alpha.3","v3.0.0-alpha-2","v0.1.0","v0.0.17","v0.0.16","v0.0.15","v0.0.13","v0.0.12","v0.0.11","v0.0.10","v0.0.9","v0.0.8","v0.0.7","v0.0.6","v0.0.5","v0.0.4","v0.0.3","v0.0.2","v0.0.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-35198.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H"}]}
