When making any HTTP request, the automatically enabled and self-managed CookieStore (aka cookie jar) will silently replace explicitly defined Cookies with any that have the same name from the cookie jar. For services that operate with multiple users, this can result in one user's Cookie being used for another user's requests.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","score":9.2},"cvss_v3":null,"cwes":["CWE-287"],"references":["https://github.com/AsyncHttpClient/async-http-client/commit/d5a83362f7aed81b93ebca559746ac9be0f95425","https://github.com/AsyncHttpClient/async-http-client/issues/1964","https://github.com/AsyncHttpClient/async-http-client/pull/2033","https://github.com/AsyncHttpClient/async-http-client/security/advisories/GHSA-mfj5-cf8g-g2fv"],"products":[],"source":"nvd","synced_at":"2026-10-19T21:57:36.180738747+00:00"},"epss":{"cve":"CVE-2024-53990","score":0.00722,"percentile":0.53993,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-mfj5-cf8g-g2fv","url":"https://osv.dev/vulnerability/GHSA-mfj5-cf8g-g2fv","summary":"AsyncHttpClient (AHC) library's `CookieStore` replaces explicitly defined `Cookie`s","modified":"2026-09-10T03:50:21.642131422Z","packages":[{"ecosystem":"Maven","name":"org.asynchttpclient:async-http-client","purl":"pkg:maven/org.asynchttpclient/async-http-client","ranges":[">=2.1.0 <2.12.4"],"fixed":["2.12.4"]},{"ecosystem":"Maven","name":"org.asynchttpclient:async-http-client","purl":"pkg:maven/org.asynchttpclient/async-http-client","ranges":[">=3.0.0.Beta1 <3.0.1"],"fixed":["3.0.1"]}]}],"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).
