Axios: Regular Expression Denial of Service (ReDoS) via Cookie Name Injection PUBLISHED

Description (CNA)

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.

A flaw was found in Axios. A remote attacker, by influencing the XSRF cookie name in a browser environment, could cause the application to construct a regular expression that leads to excessive processing. This can result in a client-side Denial of Service (DoS), where the affected browser tab may freeze, impacting the availability of the application for the user.
