CWE ID 1321


CVE-2023-26158 is a vulnerability found in all versions of the package mockjs. It is categorized as a high-risk vulnerability with a base severity score of 8.2. This vulnerability is related to prototype pollution, specifically through the Util.extend function, which does not check if the attribute resolves to the object prototype. An attacker could exploit this vulnerability by injecting user-controlled inputs into the extend() method of certain components. The affected products include various versions of tyFUC and tyFUDA. To remediate this vulnerability, a workaround is suggested by adding a denylist of dangerous attributes in the Util.extend function. This vulnerability poses a potential danger to organizations if their software relies on specific attributes or uses predefined attributes of the object prototype, as it could lead to attribute manipulation or replacement with malicious ones.
