{"id":"CVE-2026-59883","summary":"Guzzle: Cookie Disclosure and Injection via IP-Address Domains","details":"Guzzle is an extensible PHP HTTP client. Prior to 7.12.3, CookieJar did not restrict cookies scoped to IP-address or bare-numeric Domain values to the exact host that set them, because SetCookie::matchesDomain() applied ordinary suffix matching to domains such as 192.168.0.1, [::1], or 1, allowing cross-host cookie disclosure, cookie injection, or session fixation. This issue is fixed in version 7.12.3.","aliases":["GHSA-g446-98w2-8p5w"],"modified":"2026-07-16T03:47:11.389177809Z","published":"2026-07-08T15:56:03.689Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-346","CWE-384"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59883.json"},"references":[{"type":"WEB","url":"https://github.com/guzzle/guzzle/releases/tag/7.12.3"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/59xxx/CVE-2026-59883.json"},{"type":"ADVISORY","url":"https://github.com/guzzle/guzzle/security/advisories/GHSA-g446-98w2-8p5w"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-59883"},{"type":"FIX","url":"https://github.com/guzzle/guzzle/commit/b9944c161b12d9ee9c9334cfc5b9659ecd7451f8"},{"type":"FIX","url":"https://github.com/guzzle/guzzle/pull/3694"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/guzzle/guzzle","events":[{"introduced":"0"},{"fixed":"9aa17bcdd777ee31df9fc83c337ca4ca2340def3"},{"fixed":"b9944c161b12d9ee9c9334cfc5b9659ecd7451f8"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"7.12.3"}],"source":["CPE_RANGE","REFERENCES"],"cpe":"cpe:2.3:a:guzzlephp:guzzle:*:*:*:*:*:*:*:*"}}],"versions":["7.12.2","7.12.1","7.12.0","7.11.0","7.10.0","7.9.3","7.9.2","7.9.1","7.9.0","7.8.1","7.8.0","7.7.0","7.6.1","7.6.0","7.5.1","7.5.0","7.4.5","7.4.4","7.4.3","7.4.2","7.4.1","7.4.0","7.3.0","7.2.0","7.1.1","7.1.0","7.0.0","7.0.0-rc.1","7.0.0-beta.2","7.0.0-beta.1","6.5.0","6.4.1","6.4.0","6.3.3","6.3.2","6.3.1","6.3.0","6.2.2","6.2.1","4.2.3","6.2.0","6.1.1","6.1.0","6.0.2","6.0.1","6.0.0","5.3.0","5.2.0","5.1.0","5.0.3","5.0.2","5.0.1","5.0.0","4.2.2","4.2.1","4.2.0","4.1.8","4.1.7","4.1.6","4.1.5","4.1.4","4.1.3","4.1.2","4.1.1","4.1.0","4.0.2","4.0.1","4.0.0","4.0.0-rc.2","4.0.0-rc.1","v3.8.1","v3.8.0","v3.7.4","v3.7.3","v3.7.2","v3.7.1","v3.7.0","v3.6.0","v3.5.0","v3.4.3","v3.4.2","v3.4.1","v3.4.0","v3.3.1","v3.3.0","v3.2.0","v3.1.2","v3.1.1","v3.1.0","v3.0.7","v3.0.6","v3.0.5","v3.0.4","v3.0.3","v3.0.2","v3.0.1","v3.0.0","v2.8.8","v2.8.7","v2.8.6","v2.8.5","v2.8.4","v2.8.3","v2.8.2","v2.8.1","v2.8.0","v2.7.2","v2.7.1","v2.7.0","v2.6.6","v2.6.5","v2.6.4","v2.6.3","v2.6.2","v2.6.1","v2.6.0","v2.5.0","v2.4.1","v2.4.0","v2.3.2","v2.3.1","v2.3.0","v2.2.4","v2.2.3","v2.2.2","v2.2.1","v2.2.0","v2.1.4","v2.1.3","v2.1.2","v2.1.1","v2.1.0","v2.0.5","v2.0.4","v2.0.3","v2.0.2","v2.0.1","v2.0.0","v1.0.3","v1.0.2","v1.0.1","v1.0.0","v1.0.0beta1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-59883.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N"}]}
