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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","score":5.3},"cwes":["CWE-200"],"references":["https://discuss.rubyonrails.org/t/possible-sensitive-session-information-leak-in-active-storage/84945","https://github.com/rails/rails/commit/723f54566023e91060a67b03353e7c03e7436433","https://github.com/rails/rails/commit/78fe149509fac5b05e54187aaaef216fbb5fd0d3","https://github.com/rails/rails/security/advisories/GHSA-8h22-8cf7-hq6g","https://github.com/rubysec/ruby-advisory-db/blob/master/gems/activestorage/CVE-2024-26144.yml"],"products":["rubyonrails:rails"],"source":"nvd","synced_at":"2026-10-19T21:45:59.823092188+00:00"},"epss":{"cve":"CVE-2024-26144","score":0.01119,"percentile":0.66159,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-8h22-8cf7-hq6g","url":"https://osv.dev/vulnerability/GHSA-8h22-8cf7-hq6g","summary":"Rails has possible Sensitive Session Information Leak in Active Storage","modified":"2026-09-10T03:50:05.469654069Z","packages":[{"ecosystem":"RubyGems","name":"activestorage","purl":"pkg:gem/activestorage","ranges":[">=5.2.0 <6.1.7.7"],"fixed":["6.1.7.7"]},{"ecosystem":"RubyGems","name":"activestorage","purl":"pkg:gem/activestorage","ranges":[">=7.0.0 <7.0.8.1"],"fixed":["7.0.8.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
