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.","state":0,"publishedAt":"2026-09-21T17:17:38.053+00:00","modifiedAt":"2026-09-24T21:25:27.05+00:00","affected":[],"metrics":[{"system":"CVSS 3.1 · security-advisories@github.com · Secondary","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":6.2,"severity":"MEDIUM"}],"references":["https://github.com/TomWright/dasel/commit/eee03aec28d4a33d6138098d065b7b37b85e3c55","https://github.com/TomWright/dasel/releases/tag/v3.11.2","https://github.com/TomWright/dasel/security/advisories/GHSA-65gg-g7rw-6cpc"],"sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-62866","license":"NIST NVD usage terms; underlying source attribution retained","enrichment":{"sourceStatus":"Deferred","weaknesses":["CWE-129"],"productCriteria":[],"sourceDates":{"published":"2026-09-21T17:17:38.053","lastModified":"2026-09-24T21:25:27.050"},"relatedAdvisories":[],"note":"NVD analysis and CPE criteria are source context, not proof that a package or your environment is affected.
