CVE-2021-32853 · Severity: low · CVSS 3.1 · Published 2023-02-21

Erxes is an experience operating system (XOS) that consolidates marketing, sales, operations, and customer support functions—similar to HubSpot or Zendesk. The application is vulnerable to cross-site scripting (XSS) attacks that allow malicious code to execute in users' browsers when they follow a crafted link, potentially enabling attackers to steal user sessions, deface interfaces, or steal customer data without requiring any authentication.

Technologies: [erxes (npm)](https://junglewise.ai/threats/technologies/erxes). Vendors: [npm](https://junglewise.ai/threats/vendors/npm).
