In versions prior to 2.2.19, 3.1.17, and 3.2.2, ``Rack::Multipart::Parser` stores non-file form fields (parts without a `filename`) entirely in memory as Ruby `String` objects. A single large text field in a multipart/form-data request (hundreds of megabytes or more) can consume equivalent process memory, potentially leading to out-of-memory (OOM) conditions and denial of service (DoS). Attackers can send large non-file fields to trigger excessive memory usage. Impact scales with request size and concurrency, potentially leading to worker crashes or severe garbage-collection overhead. All Rack applications processing multipart form submissions are affected. Versions 2.2.19, 3.1.17, and 3.2.2 enforce a reasonable size cap for non-file fields (e.g., 2 MiB). Workarounds include restricting maximum request body size at the web-server or proxy layer (e.g., Nginx `client_max_body_size`) and validating and rejecting unusually large form fields at the application level.","severity":{"version":"3.1","score":7.5,"vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","level":"high","assessor":"cna","from":"cve"},"epss":{"day":"2026-11-09","score":0.00561,"percentile":0.46944,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":true},"cwes":["CWE-400"],"published":"2025-10-07T14:42:53Z","modified":"2026-10-29T11:32:28Z","fixes":[{"ecosystem":"RubyGems","package":"rack","fixed_in":["2.2.19","3.1.17","3.2.2"],"sources":["ghsa","osv"]},{"ecosystem":"Debian:12","package":"ruby-rack","fixed_in":["2.2.20-0+deb12u1"],"sources":["osv"]},{"ecosystem":"Debian:13","package":"ruby-rack","fixed_in":["3.1.18-1~deb13u1"],"sources":["osv"]},{"ecosystem":"Debian:14","package":"ruby-rack","fixed_in":["3.1.18-1"],"sources":["osv"]},{"ecosystem":"Ubuntu:22.04:LTS","package":"ruby-rack","fixed_in":["2.1.4-5ubuntu1.2"],"sources":["osv"]},{"ecosystem":"Ubuntu:24.04:LTS","package":"ruby-rack","fixed_in":["2.2.7-1ubuntu0.5"],"sources":["osv"]},{"ecosystem":"Ubuntu:25.10","package":"ruby-rack","fixed_in":["3.1.16-0.1ubuntu0.1"],"sources":["osv"]}],"affected":[{"source":"ghsa","ecosystem":"RubyGems","package":"rack","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.2.19"}]}]},{"source":"ghsa","ecosystem":"RubyGems","package":"rack","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.1"},{"fixed":"3.1.17"}]}]},{"source":"ghsa","ecosystem":"RubyGems","package":"rack","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"3.2"},{"fixed":"3.2.2"}]}]},{"source":"osv","ecosystem":"AlmaLinux:8","package":"pcs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.10.18-2.el8_10.7.alma.1"}]}],"bundled":5},{"source":"osv","ecosystem":"AlmaLinux:8","package":"pcs-snmp","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.10.18-2.el8_10.7.alma.1"}]}],"bundled":5},{"source":"osv","ecosystem":"AlmaLinux:9","package":"pcs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.11.10-1.el9_7.1"}]}],"bundled":5},{"source":"osv","ecosystem":"AlmaLinux:9","package":"pcs-snmp","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.11.10-1.el9_7.1"}]}],"bundled":5},{"source":"osv","ecosystem":"AlmaLinux:10","package":"cockpit-ha-cluster","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.12.1-1.el10_1.1"}]}],"bundled":5},{"source":"osv","ecosystem":"TuxCare:CentOS-Stream:8","package":"pcs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.10.18-2.el8.tuxcare.els1"}]}],"bundled":10},{"source":"osv","ecosystem":"TuxCare:CentOS-Stream:8","package":"pcs-snmp","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.10.18-2.el8.tuxcare.els1"}]}],"bundled":10},{"source":"osv","ecosystem":"TuxCare:CentOS:8.4","package":"pcs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.10.8-1.el8.tuxcare.els1"}]}],"bundled":10},{"source":"osv","ecosystem":"TuxCare:CentOS:8.4","package":"pcs-snmp","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.10.8-1.el8.tuxcare.els1"}]}],"bundled":10},{"source":"osv","ecosystem":"TuxCare:CentOS:8.5","package":"pcs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.10.8-1.el8.tuxcare.els1"}]}],"bundled":10},{"source":"osv","ecosystem":"TuxCare:CentOS:8.5","package":"pcs-snmp","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.10.8-1.el8.tuxcare.els1"}]}],"bundled":10},{"source":"osv","ecosystem":"TuxCare:OracleLinux:7","package":"pcs","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.169-3.0.1.el7_9.3.tuxcare.els1"}]}],"bundled":4},{"source":"osv","ecosystem":"TuxCare:OracleLinux:7","package":"pcs-snmp","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0.9.169-3.0.1.el7_9.3.tuxcare.els1"}]}],"bundled":4},{"source":"osv","ecosystem":"Debian:12","package":"ruby-rack","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.2.20-0+deb12u1"}]}],"versions":["2.2.13-1~deb12u1","2.2.6.4-1","2.2.6.4-1+deb12u1","2.2.7-1","2.2.7-1.1"]},{"source":"osv","ecosystem":"Debian:13","package":"ruby-rack","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.18-1~deb13u1"}]}],"versions":["3.1.16-0.1"]},{"source":"osv","ecosystem":"Debian:14","package":"ruby-rack","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.1.18-1"}]}],"versions":["3.1.16-0.1","3.1.18-1~deb13u1"]},{"source":"osv","ecosystem":"Debian:11","package":"ruby-rack","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1.4-3+deb11u4"}]}],"versions":["2.1.4-3","2.1.4-3+deb11u1","2.1.4-3+deb11u2","2.1.4-3+deb11u3"],"bundled":8},{"source":"osv","ecosystem":"Debian:12","package":"ruby-rack","ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.2.20-0+deb12u1"}]}],"versions":["2.2.13-1~deb12u1","2.2.6.4-1","2.2.6.4-1+deb12u1","2.2.7-1","2.2.7-1.1"]

A single large text field in a multipart/form-data request (hundreds of megabytes or more) can consume equivalent process memory, potentially leading to out-of-memory (OOM) conditions and denial of service (DoS).\n\n## Details\n\nDuring multipart parsing, file parts are streamed to temporary files, but non-file parts are buffered into memory:\n\n```ruby\nbody = String.new  # non-file → in-RAM buffer\n@mime_parts[mime_index].body \u003c\u003c content\n```\n\nThere is no size limit on these in-memory buffers. As a result, any large text field—while technically valid—will be loaded fully into process memory before being added to `params`.\n\n## Impact\n\nAttackers can send large non-file fields to trigger excessive memory usage. Impact scales with request size and concurrency, potentially leading to worker crashes or severe garbage-collection overhead. All Rack applications processing multipart form submissions are affected.\n\n## Mitigation\n\n* **Upgrade:** Use a patched version of Rack that enforces a reasonable size cap for non-file fields (e.g., 2 MiB).\n* **Workarounds:**\n  * Restrict maximum request body size at the web-server or proxy layer (e.g., Nginx `client_max_body_size`).\n  * Validate and reject unusually large form fields at the application
