{"id":"GHSA-q34m-jh98-gwm2","summary":"Werkzeug possible resource exhaustion when parsing file data in forms","details":"Applications using Werkzeug to parse `multipart/form-data` requests are vulnerable to resource exhaustion. A specially crafted form body can bypass the `Request.max_form_memory_size` setting.\n\n\nThe `Request.max_content_length` setting, as well as resource limits provided by deployment software and platforms, are also available to limit the resources used during a request. This vulnerability does not affect those settings. All three types of limits should be considered and set appropriately when deploying an application.","aliases":["CVE-2024-49767","PYSEC-2026-1860","PYSEC-2026-3417"],"modified":"2026-07-17T21:07:08.638225472Z","published":"2024-10-25T19:44:43Z","database_specific":{"github_reviewed_at":"2024-10-25T19:44:43Z","nvd_published_at":"2024-10-25T20:15:04Z","cwe_ids":["CWE-400"],"severity":"MODERATE","github_reviewed":true},"references":[{"type":"WEB","url":"https://github.com/pallets/werkzeug/security/advisories/GHSA-q34m-jh98-gwm2"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-49767"},{"type":"WEB","url":"https://github.com/pallets/quart/commit/5e78c4169b8eb66b91ead3e62d44721b9e1644ee"},{"type":"WEB","url":"https://github.com/pallets/quart/commit/abb04a512496206de279225340ed022852fbf51f"},{"type":"WEB","url":"https://github.com/pallets/werkzeug/commit/50cfeebcb0727e18cc52ffbeb125f4a66551179b"},{"type":"WEB","url":"https://github.com/pallets/werkzeug/commit/cbb446fdcada7685fce936ded01b76c08dbd6eb5"},{"type":"PACKAGE","url":"https://github.com/pallets/werkzeug"},{"type":"WEB","url":"https://github.com/pallets/werkzeug/releases/tag/3.0.6"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20250103-0007"}],"affected":[{"package":{"name":"werkzeug","ecosystem":"PyPI","purl":"pkg:pypi/werkzeug"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"2.0.0rc1"},{"fixed":"3.0.6"}]}],"versions":["2.0.0","2.0.0rc1","2.0.0rc2","2.0.0rc3","2.0.0rc4","2.0.0rc5","2.0.1","2.0.2","2.0.3","2.1.0","2.1.1","2.1.2","2.2.0","2.2.0a1","2.2.1","2.2.2","2.2.3","2.3.0","2.3.1","2.3.2","2.3.3","2.3.4","2.3.5","2.3.6","2.3.7","2.3.8","3.0.0","3.0.1","3.0.2","3.0.3","3.0.4","3.0.5"],"database_specific":{"last_known_affected_version_range":"\u003c= 3.0.5","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/10/GHSA-q34m-jh98-gwm2/GHSA-q34m-jh98-gwm2.json"}},{"package":{"name":"quart","ecosystem":"PyPI","purl":"pkg:pypi/quart"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.20.0"}]}],"versions":["0.1.0","0.10.0","0.11.0","0.11.1","0.11.2","0.11.3","0.11.4","0.11.5","0.12.0","0.13.0","0.13.1","0.14.0","0.14.1","0.15.0","0.15.1","0.16.0","0.16.1","0.16.2","0.16.3","0.17.0","0.18.0","0.18.1","0.18.2","0.18.3","0.18.4","0.19.0","0.19.1","0.19.2","0.19.3","0.19.4","0.19.5","0.19.6","0.19.7","0.19.8","0.19.9","0.2.0","0.3.0","0.3.1","0.4.0","0.4.1","0.5.0","0.6.0","0.6.1","0.6.10","0.6.11","0.6.12","0.6.13","0.6.14","0.6.15","0.6.2","0.6.3","0.6.4","0.6.5","0.6.6","0.6.7","0.6.8","0.6.9","0.7.0","0.7.1","0.7.2","0.8.0","0.8.1","0.9.0","0.9.1"],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2024/10/GHSA-q34m-jh98-gwm2/GHSA-q34m-jh98-gwm2.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N"}]}
