{"id":"CVE-2021-32805","details":"Flask-AppBuilder is an application development framework, built on top of Flask. In affected versions if using Flask-AppBuilder OAuth, an attacker can share a carefully crafted URL with a trusted domain for an application built with Flask-AppBuilder, this URL can redirect a user to a malicious site. This is an open redirect vulnerability. To resolve this issue upgrade to Flask-AppBuilder 3.2.2 or above. If upgrading is infeasible users may filter HTTP traffic containing `?next={next-site}` where the `next-site` domain is different from the application you are protecting as a workaround.","aliases":["GHSA-624f-cqvr-3qw4","PYSEC-2021-359"],"modified":"2026-03-13T21:59:42.257772Z","published":"2021-09-08T18:15:14.733Z","related":["GHSA-624f-cqvr-3qw4"],"references":[{"type":"ADVISORY","url":"https://github.com/dpgaspar/Flask-AppBuilder/security/advisories/GHSA-624f-cqvr-3qw4"},{"type":"FIX","url":"https://github.com/dpgaspar/Flask-AppBuilder/commit/6af28521589599b1dbafd6313256229ee9a4fa74"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/dpgaspar/flask-appbuilder","events":[{"introduced":"0"},{"fixed":"f0608fb8e420a236199b5bd439cf122769236816"},{"fixed":"6af28521589599b1dbafd6313256229ee9a4fa74"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"3.3.2"}]}}],"versions":["3.1.1","v1.10.0","v1.11.0","v1.11.1","v1.12.0","v1.12.1","v1.12.2","v1.12.3","v1.12.4","v1.12.5","v1.13.0","v1.8.1","v1.9.0","v1.9.1","v1.9.2","v1.9.3","v1.9.4","v1.9.5","v1.9.6","v2.0.0","v2.1.0","v2.1.1","v2.1.10","v2.1.11","v2.1.12","v2.1.13","v2.1.2","v2.1.3","v2.1.4","v2.1.5","v2.1.6","v2.1.7","v2.1.8","v2.1.9","v2.2.0","v2.2.1","v2.2.1rc1","v2.2.2","v2.2.3","v2.3.0","v2.3.1","v2.3.2","v2.3.3","v2.3.4","v3.0.0","v3.0.1","v3.1.0","v3.1.1","v3.2.0","v3.2.1","v3.2.2","v3.2.3","v3.3.0","v3.3.1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-32805.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
