{"id":"CVE-2026-59168","published":"2026-09-21T17:17:36.500","lastModified":"2026-09-21T21:17:06.380","description":"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.","cvssScore":6.2,"cvssSeverity":"MEDIUM","cvssVector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","cwes":["CWE-674"],"vendors":[],"products":[],"references":[{"url":"https://github.com/TomWright/dasel/commit/4c91d0d02dc59ce8404709b1bfed7a6fabe62f68","tags":[]},{"url":"https://github.com/TomWright/dasel/releases/tag/v3.11.1","tags":[]},{"url":"https://github.com/TomWright/dasel/security/advisories/GHSA-cqxr-jxr2-85pq","tags":[]}],"exploitRefs":[{"url":"https://github.com/TomWright/dasel/commit/4c91d0d02dc59ce8404709b1bfed7a6fabe62f68","tags":[]},{"url":"https://github.com/TomWright/dasel/releases/tag/v3.11.1","tags":[]},{"url":"https://github.com/TomWright/dasel/security/advisories/GHSA-cqxr-jxr2-85pq","tags":[]}],"hasPoc":true,"ai":{"summary":"The flaw allows deep nesting of JSON or XML data to exhaust the Go goroutine stack, leading to a fatal error.
