{"id":"UBUNTU-CVE-2026-59168","details":"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.","modified":"2026-09-24T02:00:25.848668989Z","published":"2026-09-21T17:17:00Z","upstream":["CVE-2026-59168"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-59168"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-59168"},{"type":"REPORT","url":"https://github.com/TomWright/dasel/commit/4c91d0d02dc59ce8404709b1bfed7a6fabe62f68"},{"type":"REPORT","url":"https://github.com/TomWright/dasel/releases/tag/v3.11.1"},{"type":"REPORT","url":"https://github.com/TomWright/dasel/security/advisories/GHSA-cqxr-jxr2-85pq"}],"affected":[{"package":{"name":"dasel","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/dasel?arch=source&distro=esm-apps%2Fnoble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.6.0-1","2.6.0-1build1","2.6.0-1ubuntu0.1","2.6.0-1ubuntu0.2","2.6.0-1ubuntu0.2+esm1","2.6.0-1ubuntu0.3","2.6.0-1ubuntu0.3+esm1","2.6.0-1ubuntu0.3+esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"2.6.0-1ubuntu0.3+esm2","binary_name":"dasel"},{"binary_version":"2.6.0-1ubuntu0.3+esm2","binary_name":"golang-github-tomwright-dasel-dev"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59168.json"}},{"package":{"name":"dasel","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/dasel?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.8.1-1","2.8.1-1build1"],"ecosystem_specific":{"binaries":[{"binary_name":"dasel","binary_version":"2.8.1-1build1"},{"binary_name":"golang-github-tomwright-dasel-dev","binary_version":"2.8.1-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-59168.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
