Summary
Prototype Pollution Protection Bypass in qs
Details
Affected version of qs are vulnerable to Prototype Pollution because it is possible to bypass the protection. The qs.parse function fails to properly prevent an object's prototype to be altered when parsing arbitrary input. Input containing [ or ] may bypass the prototype pollution protection and alter the Object prototype. This allows attackers to override properties that will exist in all objects, which may lead to Denial of Service or Remote Code Execution in specific circumstances.
Recommendation
Upgrade to 6.0.4, 6.1.2, 6.2.3, 6.3.2 or later.
