1) Code Injection (CVE-ID: CVE-2026-21884)

CWE-ID: CWE-94 - Improper Control of Generation of Code ('Code Injection')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:N/SC:L/SI:L/SA:N/E:U/U:Amber


The vulnerability allows a remote attacker to execute arbitrary code on the target system.

The vulnerability exists due to improper input validation within API in Framework Mode when using the getKey/storageKey props during server-side rendering. A remote attacker can pass specially crafted request and execute arbitrary JavaScript code during SSR if untrusted content is used to generate the keys.

Successful exploitation of this vulnerability requires that server-side rendering in Framework Mode is enabled.
