CVE-2025-13158: Apidoc Apidoc-Core

Critical severity, CVSS 9.3. EPSS: 0.5% chance of exploitation in the next 30 days.

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.

Affected products
