There are packages installed that are affected by a vulnerability referenced in the following CVE:

  - shell-quote's `quote()` function did not validate object-token inputs against the operator model used by
    `parse()`. The `.op` field was backslash-escaped character by character using `/(.)/g`, which in
    JavaScript does not match line terminators (\n, \r, U+2028, U+2029). A line terminator in `.op` therefore
    passed through unescaped into the output; POSIX shells treat a literal newline as a command separator, so
    any content after it would execute as a second command. The vulnerable code path is reachable in two ways:
    (1) direct construction of `{ op: '...\n...' }` from external input, and (2) via `parse(cmd, envFn)` when
    `envFn` returns object tokens whose `.op` is attacker-influenced. Both are documented API surface. Fixed
    by replacing the per-character escape with strict shape validation: `.op` must match the parser's control-
    operator allowlist; `{ op: 'glob', pattern }` validates `pattern` and forbids line terminators; `{ comment
    }` validates `comment` and forbids line terminators; any other object shape throws `TypeError`.
    (CVE-2026-9277)

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