Linux Distros Unpatched Vulnerability : CVE-2026-46377

medium Nessus Plugin ID 327667

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

- 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. (CVE-2026-46377)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
