{"id":"CVE-2026-46377","aliases":["GHSA-m5j3-4634-c2vq","GO-2026-5491"],"url":"https://o3.security/vulnerability/CVE-2026-46377","summary":"Dasel: Index-out-of-range panic in dasel selector lexer on trailing backslash in quoted string","details":"Dasel is a command-line tool and library for querying, modifying, and transforming data structures. From 3.0.0 until 3.10.1, the escape sequence handler in (*Tokenizer).parseCurRune in selector/lexer/tokenize.go increments past a trailing backslash in a quoted string such as \"\\ or '\\ and then reads p.src[pos] without a bounds check, allowing attacker-controlled selector strings to trigger a Go index-out-of-range panic. This issue is fixed in version 3.10.1.","published":"2026-07-16T17:57:16.643Z","modified":"2026-08-12T03:51:13.841597996Z","cvss":{"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"},"epss":{"score":0.00128,"percentile":0.02844,"asOf":"2026-08-15"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/tomwright/dasel/v3","fixedVersion":null}],"fix":{"url":"https://github.com/TomWright/dasel/commit/5fc1172287df89860caf139b146007d7ed12178c","label":"TomWright/dasel@5fc1172"},"references":[{"type":"WEB","url":"https://github.com/TomWright/dasel/releases/tag/v3.10.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46377.json"},{"type":"ADVISORY","url":"https://github.com/TomWright/dasel/security/advisories/GHSA-m5j3-4634-c2vq"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46377"},{"type":"FIX","url":"https://github.com/TomWright/dasel/commit/5fc1172287df89860caf139b146007d7ed12178c"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:13.841597996Z"}}
