qwik

Qwik is a performance focused javascript framework.qwik <=1.19.0 is vulnerable to RCE due to an unsafe deserialization vulnerability in the server$ RPC mechanism that allows any unauthenticated user to execute arbitrary code on the server with a single HTTP request. Affects any deployment where require() is available at runtime. This vulnerability is fixed in 1.19.1.

CVE-2026-27971 is a critical vulnerability affecting the Qwik JavaScript framework versions up to 1.19.0. The root cause is unsafe deserialization of untrusted data within the server-side RPC mechanism. Specifically, the server component of qwik processes RPC requests that deserialize data without proper validation or sanitization, allowing an attacker to craft malicious payloads that lead to arbitrary code execution on the server. This vulnerability is particularly dangerous because it requires no authentication or user interaction and can be triggered with a single HTTP request. The presence of the require() function at runtime on the server side enables attackers to load and execute arbitrary modules or code, amplifying the impact. The vulnerability is classified under CWE-502, which involves deserialization of untrusted data leading to security issues. The flaw was publicly disclosed on March 3, 2026, with a CVSS 4.0 base score of 9.2, indicating critical severity. The issue was resolved in qwik version 1.19.1, which includes fixes to safely handle deserialization and restrict unsafe code execution paths. No known exploits have been reported in the wild yet, but the vulnerability's characteristics make it a prime target for attackers seeking remote code execution on servers running vulnerable qwik versions. This affects any deployment scenario where the server-side runtime environment exposes require() and processes RPC calls using the vulnerable mechanism.
