CVE-2026-59168

Summary

Dasel is a command-line tool and library for querying, modifying, and transforming data structures. From 3.0.0 until 3.11.1, parsing/json/json_reader.go decodeValue, decodeObject, and decodeArray, and parsing/xml/reader.go parseElement, recurse once per input nesting level without a depth guard. Deeply nested attacker-controlled JSON or XML supplied through parsing.Format(…).NewReader(…).Read(data), the command-line interface, or the parse selector function can exhaust the Go goroutine stack and raise an unrecoverable fatal error that terminates the entire process. The XML input-size limit does not prevent depth exhaustion, and defer or recover cannot intercept the failure. This issue is fixed in version 3.11.1.
