dasel: Dasel is a command-line tool and library for querying, modifying, and transforming data structures
CVE-2026-62866 is fixed in dasel on 1 platform by DEBIAN-CVE-2026-62866 (version 3.11.2-1), released September 24, 2026. It is not reported as exploited. Patch Radar priority: Routine.
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.
