Browsers may allow \"nameless\" cookies that look like `=value` instead of `key=value`. A vulnerable browser may allow a compromised application on an adjacent subdomain to exploit this to set a cookie like `=__Host-test=bad` for another subdomain. Werkzeug prior to 2.2.3 will parse the cookie `=__Host-test=bad` as __Host-test=bad`. If a Werkzeug application is running next to a vulnerable or malicious subdomain which sets such a cookie using a vulnerable browser, the Werkzeug application will see the bad cookie value but the valid cookie key. The issue is fixed in Werkzeug 2.2.3."}],"metrics":{"cvssMetricV31":[{"source":"security-advisories@github.com","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:A/AC:H/PR:N/UI:R/S:U/C:N/I:L/A:N","baseScore":2.6,"baseSeverity":"LOW","attackVector":"ADJACENT_NETWORK","attackComplexity":"HIGH","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":1.2,"impactScore":1.4},{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:U/C:N/I:L/A:N","baseScore":3.5,"baseSeverity":"LOW","attackVector":"ADJACENT_NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"NONE","integrityImpact":"LOW","availabilityImpact":"NONE"},"exploitabilityScore":2.1,"impactScore":1.4}]},"weaknesses":[{"source":"security-advisories@github.com","type":"Secondary","description":[{"lang":"en","value":"CWE-20"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"NVD-CWE-noinfo"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:palletsprojects:werkzeug:*:*:*:*:*:*:*:*","versionEndExcluding":"2.2.3","matchCriteriaId":"EE8F26B3-94E2-45A2-A114-56AF4D262414"}]}]}],"references":[{"url":"https://github.com/pallets/werkzeug/commit/cf275f42acad1b5950c50ffe8ef58fe62cdce028","source":"security-advisories@github.com","tags":["Patch"]},{"url":"https://github.com/pallets/werkzeug/releases/tag/2.2.3","source":"security-advisories@github.com","tags":["Release Notes"]},{"url":"https://github.com/pallets/werkzeug/security/advisories/GHSA-px8h-6qxv-m22q","source":"security-advisories@github.com","tags":["Vendor Advisory"]},{"url":"https://security.netapp.com/advisory/ntap-20230818-0003/","source":"security-advisories@github.com"},{"url":"https://www.debian.org/security/2023/dsa-5470","source":"security-advisories@github.com"},{"url":"https://github.com/pallets/werkzeug/commit/cf275f42acad1b5950c50ffe8ef58fe62cdce028","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Patch"]},{"url":"https://github.com/pallets/werkzeug/releases/tag/2.2.3","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Release Notes"]},{"url":"https://github.com/pallets/werkzeug/security/advisories/GHSA-px8h-6qxv-m22q","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Vendor Advisory"]},{"url":"https://security.netapp.com/advisory/ntap-20230818-0003/","source":"af854a3a-2127-422b-91ae-364da2661108"},{"url":"https://www.debian.org/security/2023/dsa-5470","source":"af854a3a-2127-422b-91ae-364da2661108"}]}}]}
