{"id":"BIT-rails-2024-26144","summary":"Possible Sensitive Session Information Leak in Active Storage","details":"Rails is a web-application framework. Starting with version 5.2.0, there is a possible sensitive session information leak in Active Storage. By default, Active Storage sends a Set-Cookie header along with the user's session cookie when serving blobs. It also sets Cache-Control to public. Certain proxies may cache the Set-Cookie, leading to an information leak. The vulnerability is fixed in 7.0.8.1 and 6.1.7.7.","aliases":["CVE-2024-26144","GHSA-8h22-8cf7-hq6g"],"modified":"2025-05-20T10:02:07.006Z","published":"2024-12-20T09:50:06.835Z","database_specific":{"cpes":["cpe:2.3:a:rubyonrails:rails:*:*:*:*:*:ruby:*:*"],"severity":"Medium"},"references":[{"type":"WEB","url":"https://discuss.rubyonrails.org/t/possible-sensitive-session-information-leak-in-active-storage/84945"},{"type":"WEB","url":"https://github.com/rails/rails/commit/723f54566023e91060a67b03353e7c03e7436433"},{"type":"WEB","url":"https://github.com/rails/rails/commit/78fe149509fac5b05e54187aaaef216fbb5fd0d3"},{"type":"WEB","url":"https://github.com/rails/rails/security/advisories/GHSA-8h22-8cf7-hq6g"},{"type":"WEB","url":"https://github.com/rubysec/ruby-advisory-db/blob/master/gems/activestorage/CVE-2024-26144.yml"},{"type":"WEB","url":"https://security.netapp.com/advisory/ntap-20240510-0013/"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2024-26144"}],"affected":[{"package":{"name":"rails","ecosystem":"Bitnami","purl":"pkg:bitnami/rails"},"ranges":[{"type":"SEMVER","events":[{"introduced":"5.2.0"},{"fixed":"6.1.8"},{"introduced":"7.0.0"},{"fixed":"7.0.9"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/rails/BIT-rails-2024-26144.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}],"schema_version":"1.7.3"}
