CVE-2022-23395Network attack vector

DOM XSS via unchecked cookie-name assignment

Published Mar 2, 2022 · Updated Aug 3, 2024

DOM cross-site scripting in jQuery Cookie 1.4.1 allows remote attackers to execute script in a user's browser through crafted cookie data. When reading all cookies, $.cookie() decodes attacker-controlled names and JSON values and assigns them to a plain result object without blocking the proto key. Exploitation requires JSON cookie parsing and a consuming application that sends an inherited property to an unsafe DOM sink; Debian classifies the behavior as an application-level sanitization issue rather than a jquery-cookie flaw.
