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."}], "lastModified": "2024-11-21T07:47:07.947", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:palletsprojects:werkzeug:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "EE8F26B3-94E2-45A2-A114-56AF4D262414", "versionEndExcluding": "2.2.3"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
