From 2.16.0 until 3.0.14, ThreadSafeCookieStore incompletely validates cookie Domain attributes. Missing private-section and default public-suffix rules, absent A-label normalization, locale-sensitive lowercasing, public-suffix host-only handling, and numeric or IP host checks allow one origin to store a cookie later sent to another origin. Applications sharing one client across trust domains can therefore receive attacker-injected cookies and may be exposed to session fixation. This issue is fixed in version 3.0.14.","published":"2026-10-07T21:17:15.000Z","lastModified":"2026-10-08T20:35:31.000Z","status":"Awaiting Analysis","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:N/I:L/A:N"},"cwe":["CWE-384","CWE-1275"],"affected":[],"epss":{"score":0.00261,"percentile":0.17789,"date":"2026-10-27","history":[{"date":"2026-10-08","score":0.00261,"percentile":0.16373}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.26%).
