Ecosystem-wide dependent count for version 0.28.0.

DescriptionCVE.org

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.

AnalysisAI

Uncontrolled recursion in axios's formDataToJSON helper allows remote, unauthenticated attackers to exhaust the JavaScript call stack and deny service to affected Node.js applications. axios versions 0.28.0 through 0.32.x and 1.0.0 through 1.17.x are affected wherever attacker-controlled FormData field names are deserialized with Content-Type: application/json, causing a RangeError that kills the request or terminates the process. No public exploit has been identified at time of analysis, but the GHSA advisory discloses sufficient technical detail - including the exact vulnerable function and the attack payload pattern - for independent reproduction; fixed releases 0.33.0 and 1.18.0 are available.

Technical ContextAI

axios is among the most widely deployed HTTP client libraries in the JavaScript ecosystem, available on npm (cpe:2.3:a:axios:axios). The vulnerable code lives in lib/helpers/formDataToJSON.js, introduced in version 0.28.0. The function parsePropPath() tokenises a FormData field name like a[x][x][x] into an array of path segments, then buildPath() recurses one call per segment to reconstruct a nested object - with no depth guard. This violates CWE-400 (Uncontrolled Resource Consumption): an adversary supplies a field name with thousands of bracket-delimited segments, forcing thousands of recursive stack frames until the JavaScript engine throws RangeError: Maximum call stack size exceeded. The symmetric inverse helper toFormData already enforces a maxDepth guard and raises AxiosError ERR_FORM_DATA_DEPTH_EXCEEDED, but this protection was never applied to formDataToJSON. The attack surface activates only when axios serialises FormData with Content-Type: application/json, either via direct calls to axios.formToJSON() or via the default transformRequest pipeline when that content-type is set.

RemediationAI

The primary fix is upgrading axios to version 0.33.0 (for the 0.x line) or 1.18.0 (for the 1.x line), as documented in the GitHub Security Advisory GHSA-pmv8-rq9r-6j72 and implemented in upstream pull requests https://github.com/axios/axios/pull/11000 and https://github.com/axios/axios/pull/11001. These releases introduce a depth guard in buildPath() analogous to the existing maxDepth protection in toFormData. If an immediate upgrade is not feasible, the principal compensating control is to validate and reject FormData field names containing deeply nested bracket sequences before they reach axios - for example, stripping or refusing any key where the bracket-segment count exceeds a safe threshold (e.g., 20). A second workaround is to avoid setting Content-Type: application/json when submitting FormData, which prevents the vulnerable formDataToJSON code path from being invoked; however, this may change application behaviour if JSON serialisation of form data is intentional. Wrapping axios calls in try/catch with process.uncaughtException handlers prevents process termination but does not prevent per-request DoS. None of the workarounds are substitutes for upgrading.
