{"id":"CVE-2026-62866","url":"https://www.cyber-defence.io/tools/cve/CVE-2026-62866","generatedAt":"2026-10-28T04:15:13.712Z","title":"Dasel is a command-line tool and library for querying, modifying, and transforming data structures.","description":"Dasel is a command-line tool and library for querying, modifying, and transforming data structures. From 3.0.0 until 3.11.2, selector/lexer/tokenize.go parseCurRune advances the input index across trailing whitespace and then reads the source at the exhausted index without an end-of-input check. A selector ending in whitespace, including input passed through lexer.NewTokenizer(...).Tokenize() or dasel.Query, can therefore cause an index-out-of-range panic and terminate the process. This issue is fixed in version 3.11.2.","published":"2026-09-21T17:17:38.000Z","lastModified":"2026-09-24T21:25:27.000Z","status":"Deferred","sourceIdentifier":"security-advisories@github.com","cvss":{"version":"3.1","score":6.2,"severity":"MEDIUM","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-129"],"affected":[],"epss":{"score":0.00192,"percentile":0.08828,"date":"2026-10-27","history":[{"date":"2026-09-22","score":0.00194,"percentile":0.09399}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.19%).
