The vulnerability of the Faraday::NestedParamsEncoder component in the HTTP client library for Ruby allows a attacker to trigger a service failure.

The vulnerability of the Faraday::NestedParamsEncoder component in the HTTP client library for Ruby lies in its uncontrolled recursion. Exploiting this vulnerability could allow a malicious actor to cause service failures...

CVE-2026-54297

A flaw was found in Faraday, an HTTP client library. The Faraday::NestedParamsEncoder, which handles nested query parameters, does not limit the depth of nested query strings during decoding. A remote attacker can exploit this by sending a specially crafted query string, causing the application t...

CVE-2026-54297: Uncontrolled Recursion

Faraday is an HTTP client library abstraction layer that provides a common interface over many adapters. From 1.0.0 until 1.10.6 and 2.14.3, Faraday::NestedParamsEncoder, the default nested query parameter encoder/decoder in Faraday, decodes nested query strings without enforcing a maximum nestin...

Faraday - Uncontrolled recursion in NestedParamsEncoder allows stack exhaustion DoS via deeply nested query parameters

Uncontrolled Recursion in NestedParamsEncoder Allows Stack Exhaustion DoS via Deeply Nested Query Parameters Summary Faraday::NestedParamsEncoder, the default nested query parameter encoder/decoder in Faraday, decodes nested query strings without enforcing a maximum nesting depth. A crafted query...
