In affected versions of dojo (NPM package), the deepCopy method is vulnerable to Prototype Pollution. Prototype Pollution refers to the ability to inject properties into existing JavaScript language construct prototypes, such as objects. An attacker manipulates these attributes to overwrite, or pollute, a JavaScript application object prototype of the base object by injecting other values. This has been patched in versions 1.12.8, 1.13.7, 1.14.6, 1.15.3 and 1.16.2
AnalysisAI
In affected versions of dojo (NPM package), the deepCopy method is vulnerable to Prototype Pollution. Rated high severity (CVSS 7.7), this vulnerability is remotely exploitable. Public exploit code available.
Technical ContextAI
This vulnerability is classified as Code Injection (CWE-94), which allows attackers to inject and execute arbitrary code within the application.
