Description
Duplicate Advisory: Axios: Deep formToJSON Key Recursion Can Cause Denial of Service ## Duplicate Advisory This advisory has been withdrawn because it is a duplicate of GHSA-pmv8-rq9r-6j72. This link is maintained to preserve external references. ## Original Description 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.
