{"id":"GHSA-3fvr-2jw6-crq4","summary":"Duplicate Advisory: Guzzle: Unbounded response cookies risk denial of service","details":"## Duplicate Advisory\n\nThis advisory has been withdrawn because it is a duplicate of GHSA-f283-ghqc-fg79. This link is maintained to preserve external references.\n\n## Original Description\nguzzlehttp/guzzle versions before 7.15.1 contain a denial of service vulnerability in the CookieJar that accepts unlimited Set-Cookie header fields with no size restrictions. Attackers can return many large cookies from a malicious server, causing Guzzle to store excessive data in memory and generate oversized Cookie headers that fail in handlers or destination servers.","modified":"2026-09-15T06:34:19.115973979Z","published":"2026-08-01T15:30:30Z","withdrawn":"2026-08-04T12:58:31Z","database_specific":{"github_reviewed":true,"github_reviewed_at":"2026-08-04T12:58:31Z","nvd_published_at":"2026-08-01T13:17:06Z","cwe_ids":["CWE-770"],"severity":"MODERATE"},"references":[{"type":"WEB","url":"https://github.com/guzzle/guzzle/security/advisories/GHSA-f283-ghqc-fg79"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-67353"},{"type":"WEB","url":"https://www.vulncheck.com/advisories/guzzlehttp-guzzle-before-unbounded-cookie-denial-of-service"}],"affected":[{"package":{"name":"guzzlehttp/guzzle","ecosystem":"Packagist","purl":"pkg:composer/guzzlehttp/guzzle"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["4.0.0","4.0.0-rc.1","4.0.0-rc.2","4.0.1","4.0.2","4.1.0","4.1.1","4.1.2","4.1.3","4.1.4","4.1.5","4.1.6","4.1.7","4.1.8","4.2.0","4.2.1","4.2.2","4.2.3","4.2.4","5.0.0","5.0.1","5.0.2","5.0.3","5.1.0","5.2.0","5.3.0","5.3.1","5.3.2","5.3.3","5.3.4","6.0.0","6.0.1","6.0.2","6.1.0","6.1.1","6.2.0","6.2.1","6.2.2","6.2.3","6.3.0","6.3.1","6.3.2","6.3.3","6.4.0","6.4.1","6.5.0","6.5.1","6.5.2","6.5.3","6.5.4","6.5.5","6.5.6","6.5.7","6.5.8","7.0.0","7.0.0-beta.1","7.0.0-beta.2","7.0.0-rc.1","7.0.1","7.1.0","7.1.1","7.10.0","7.10.1","7.10.2","7.10.3","7.10.4","7.10.5","7.10.6","7.11.0","7.11.1","7.11.2","7.12.0","7.12.1","7.12.2","7.12.3","7.13.0","7.13.1","7.13.2","7.13.3","7.14.0","7.14.1","7.14.2","7.15.0","7.15.1","7.15.2","7.15.3","7.15.4","7.15.5","7.2.0","7.3.0","7.4.0","7.4.1","7.4.2","7.4.3","7.4.4","7.4.5","7.5.0","7.5.1","7.5.2","7.5.3","7.6.0","7.6.1","7.7.0","7.7.1","7.8.0","7.8.1","7.8.2","7.9.0","7.9.1","7.9.2","7.9.3","8.0.0","8.0.1","8.0.2","8.0.3","8.1.0","8.2.0","v1.0.3","v1.0.4","v2.0.0","v2.0.1","v2.0.2","v2.0.3","v2.0.4","v2.0.5","v2.1.0","v2.1.1","v2.1.2","v2.1.3","v2.1.4","v2.2.0","v2.2.1","v2.2.2","v2.2.3","v2.2.4","v2.3.2","v2.4.0","v2.4.1","v2.5.0","v2.6.0","v2.6.1","v2.6.2","v2.6.3","v2.6.4","v2.6.5","v2.6.6","v2.7.0","v2.7.1","v2.7.2","v2.8.0","v2.8.1","v2.8.2","v2.8.3","v2.8.4","v2.8.5","v2.8.6","v2.8.7","v2.8.8","v3.0.0","v3.0.1","v3.0.2","v3.0.3","v3.0.4","v3.0.5","v3.0.6","v3.0.7","v3.1.0","v3.1.1","v3.1.2","v3.2.0","v3.3.0","v3.3.1","v3.4.0","v3.4.1","v3.4.2","v3.4.3","v3.5.0","v3.6.0","v3.7.0","v3.7.1","v3.7.2","v3.7.3","v3.7.4","v3.8.0","v3.8.1"],"database_specific":{"last_known_affected_version_range":"\u003c 7.15.1","source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/08/GHSA-3fvr-2jw6-crq4/GHSA-3fvr-2jw6-crq4.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X"}]}
