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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","score":6.2},"cwes":["CWE-129"],"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","https://github.com/TomWright/dasel/security/advisories/GHSA-65gg-g7rw-6cpc"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:55:23.253742848+00:00"},"epss":{"cve":"CVE-2026-62866","score":0.00192,"percentile":0.0895,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-65gg-g7rw-6cpc","url":"https://osv.dev/vulnerability/GHSA-65gg-g7rw-6cpc","summary":"Dasel: Selector lexer panics on trailing whitespace in `parseCurRune`","modified":"2026-10-01T20:55:58.390167711Z","packages":[{"ecosystem":"Go","name":"github.com/tomwright/dasel/v3","purl":"pkg:golang/github.com/tomwright/dasel/v3","ranges":[">=3.0.0 <3.11.2"],"fixed":["3.11.2"]}]},{"id":"GO-2026-6548","url":"https://osv.dev/vulnerability/GO-2026-6548","summary":"Dasel: Selector lexer panics on trailing whitespace in `parseCurRune` in github.com/tomwright/dasel","modified":"2026-10-01T20:45:12.227196328Z","packages":[{"ecosystem":"Go","name":"github.com/tomwright/dasel","purl":"pkg:golang/github.com/tomwright/dasel","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/tomwright/dasel/v2","purl":"pkg:golang/github.com/tomwright/dasel/v2","ranges":["all versions"],"fixed":[]},{"ecosystem":"Go","name":"github.com/tomwright/dasel/v3","purl":"pkg:golang/github.com/tomwright/dasel/v3","ranges":[">=3.0.0 <3.11.2"],"fixed":["3.11.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
