Summary
A vulnerability in Axios versions before 0.32.0 (0.x line) and before 1.16.0 (1.x line) builds a regular expression from the configured XSRF cookie name without escaping regex metacharacters. An attacker who can influence the cookie name passed to Axios can cause expensive regex backtracking while Axios reads document.cookie, leading to client-side availability degradation.
Risk Assessment
The risk for the organization is potential freezing of the affected browser tab while Axios prepares a request, which can disrupt web application functionality and degrade user experience. The issue does not affect standard Node.js HTTP adapter usage, React Native, or web workers.
Recommendation
Immediately update Axios to version 0.32.0 or later (for the 0.x line) and to version 1.16.0 or later (for the 1.x line). If an update is not possible, avoid using XSRF configuration with user-controlled cookie names.
Original NVD description (English source)
Axios is a promise based HTTP client for the browser and Node.js. Axios versions before 0.32.0 on the 0.x line and before 1.16.0 on the 1.x line build a regular expression from the configured XSRF cookie name without escaping regex metacharacters. In standard browser environments, an attacker who can influence the cookie name passed to axios can cause expensive regex backtracking while axios reads document.cookie. The practical impact is client-side availability degradation, such as freezing the affected browser tab while axios prepares a request. The issue does not affect ordinary Node.js HTTP adapter usage, React Native, or web workers, where axios does not read document.cookie. This vulnerability is fixed in 0.32.0 and 1.16.0.
