Versions prior to 4.6.2 would allow for a malicious unauthenticated actor to perform an open redirect by manipulating the Host header in HTTP requests. Flask-AppBuilder 4.6.2 introduced the `FAB_SAFE_REDIRECT_HOSTS` configuration variable, which allows administrators to explicitly define which domains are considered safe for redirection. As a workaround, use a reverse proxy to enforce trusted host headers.","published":"2025-05-16T13:51:55.581Z","modified":"2026-07-15T01:49:05.944442003Z","cvss":{"score":4.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"PyPI","name":"flask-appbuilder","fixedVersion":"4.6.2"}],"fix":{"url":"https://github.com/dpgaspar/Flask-AppBuilder/commit/32eedbbb5cb483a3e782c5f2732de4a6a650d9b6","label":"dpgaspar/Flask-AppBuilder@32eedbb"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/32xxx/CVE-2025-32962.json"},{"type":"ADVISORY","url":"https://github.com/dpgaspar/Flask-AppBuilder/security/advisories/GHSA-99pm-ch96-ccp2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-32962"},{"type":"FIX","url":"https://github.com/dpgaspar/Flask-AppBuilder/commit/32eedbbb5cb483a3e782c5f2732de4a6a650d9b6"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-15T01:49:05.944442003Z"}}
