NVD Description

Note: Versions mentioned in the description apply only to the upstream kibana-9.4 package and not the kibana-9.4 package as distributed by Chainguard. See How to fix? for Chainguard relevant fixed versions and status.

Hono is a Web application framework that provides support for any JavaScript runtime. Prior to 4.12.21, the serialize() function in hono/cookie validates domain and path options against characters that corrupt Set-Cookie header syntax (;, \r, \n), but does not apply the same validation to sameSite and priority. An application that passes user-controlled input into either option may produce a Set-Cookie response header containing attacker-chosen additional attributes. This vulnerability is fixed in 4.12.21.
