Dasel
Parameter Value
CVSS 6.2 (MEDIUM)
Fixed In 3.10.1
Type CWE-129 (Improper Validation of Array Index)
Vendor Dasel
Public PoC No

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.
