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."}], "source": {"advisory": "GHSA-px8h-6qxv-m22q", "discovery": "UNKNOWN"}}, "adp": [{"providerMetadata": {"orgId": "af854a3a-2127-422b-91ae-364da2661108", "shortName": "CVE", "dateUpdated": "2024-08-02T10:49:07.628Z"}, "title": "CVE Program Container", "references": [{"name": "https://github.com/pallets/werkzeug/security/advisories/GHSA-px8h-6qxv-m22q", "tags": ["x_refsource_CONFIRM", "x_transferred"], "url": "https://github.com/pallets/werkzeug/security/advisories/GHSA-px8h-6qxv-m22q"}, {"name": "https://github.com/pallets/werkzeug/commit/cf275f42acad1b5950c50ffe8ef58fe62cdce028", "tags": ["x_refsource_MISC", "x_transferred"], "url": "https://github.com/pallets/werkzeug/commit/cf275f42acad1b5950c50ffe8ef58fe62cdce028"}, {"name": "https://github.com/pallets/werkzeug/releases/tag/2.2.3", "tags": ["x_refsource_MISC", "x_transferred"], "url": "https://github.com/pallets/werkzeug/releases/tag/2.2.3"}, {"url": "https://www.debian.org/security/2023/dsa-5470", "tags": ["x_transferred"]}, {"url": "https://security.netapp.com/advisory/ntap-20230818-0003/", "tags": ["x_transferred"]}]}, {"metrics": [{"other": {"type": "ssvc", "content": {"timestamp": "2025-03-10T20:57:36.294064Z", "id": "CVE-2023-23934", "options": [{"Exploitation": "none"}, {"Automatable": "no"}, {"Technical Impact": "partial"}], "role": "CISA Coordinator", "version": "2.0.3"}}}], "title": "CISA ADP Vulnrichment", "providerMetadata": {"orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2025-03-10T21:11:36.910Z"}}]}}
