Go to dashboardDasel, a Go command-line tool and library for querying and transforming JSON, XML and other data, recurses once per nesting level when parsing JSON and XML with no depth limit. Deeply nested attacker-supplied input exhausts the goroutine stack and crashes the whole process, which is a denial of service.
Summary written from the sources below. Check the originals before acting.

| Product | Ecosystem | Affected | Fixed in |
|---|---|---|---|
| github.com/tomwright/dasel | go | all versions | – |
| github.com/tomwright/dasel/v2 | go | all versions | – |
| github.com/tomwright/dasel/v3 | go | >= 3.0.0, < 3.11.1 | 3.11.1 |
Run go list -m github.com/tomwright/dasel/v3 and check whether the version is >= 3.0.0 and < 3.11.1.
If you call dasel as a library, search your code for parsing.Format(...).NewReader(...) or the parse selector function applied to untrusted input.
Upgrade github.com/tomwright/dasel/v3 to 3.11.1 or later.
Each row is the first time that source carried this signal. The analyst’s rows are its own findings.
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.
