Prototype Pollution in apidoc-core preProcess() Causes DoS

Publication date: 2025-12-26

Last updated on: 2025-12-26

Assigner: Sonatype

Description
Prototype pollution vulnerability in apidoc-core versions 0.2.0 and all subsequent versions allows remote attackers to modify JavaScript object prototypes via malformed data structures, including the “define” property processed by the application, potentially leading to denial of service or unintended behavior in applications relying on the integrity of prototype chains. This affects the preProcess() function in api_group.js, api_param_title.js, api_use.js, and api_permission.js worker modules.

Executive Summary

This vulnerability is a prototype pollution issue in apidoc-core versions 0.2.0 and later. It allows remote attackers to modify JavaScript object prototypes by sending malformed data structures, including the 'define' property. This can affect the preProcess() function in several worker modules, potentially causing denial of service or unexpected behavior in applications that depend on the integrity of prototype chains.

Impact Analysis

The vulnerability can lead to denial of service or unintended behavior in applications that rely on the integrity of JavaScript prototype chains. This means attackers could disrupt normal application operations or cause the application to behave unpredictably.

Mitigation Strategies

To mitigate this vulnerability, immediately update apidoc-core to a version later than 0.2.0 where the issue is fixed. Additionally, review and sanitize any input data structures processed by the application, especially those involving the 'define' property, to prevent prototype pollution. Monitor application behavior for signs of denial of service or unexpected behavior related to prototype chain manipulation. [1]
