Detailsinfo

A vulnerability was found in axios up to 0.32.9/1.17.9. It has been classified as problematic. This affects the function buildPath of the component FormData JSON Serializer. The manipulation with an unknown input leads to a recursion vulnerability. CWE is classifying the issue as CWE-674. The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack. This is going to have an impact on availability. The summary by CVE is:

axios versions from 0.28.0 before 0.33.0 and from 1.0.0 before 1.18.0 contain uncontrolled recursion in formDataToJSON (exposed as axios.formToJSON() and used internally when serializing FormData with Content-Type: application/json). When an application passes attacker-controlled FormData field names, a field name with thousands of nested bracket-delimited segments causes unbounded recursion in buildPath(), exhausting the JavaScript call stack (RangeError: Maximum call stack size exceeded) and causing denial of service for that request, or process termination in applications without appropriate error handling.

The advisory is shared at github.com. This vulnerability is uniquely identified as CVE-2026-67312 since 07/29/2026. The exploitability is told to be easy. It is possible to initiate the attack remotely. No form of authentication is needed for exploitation. Technical details are known, but no exploit is available. MITRE ATT&CK project uses the attack technique T1499 for this issue.

The vulnerability scanner Nessus provides a plugin with the ID 331611 (Linux Distros Unpatched Vulnerability : CVE-2026-67312), which helps to determine the existence of the flaw in a target environment.

Upgrading to version 0.33.0 or 1.18.0 eliminates this vulnerability.
