SCA: security update for js-toml (GHSA-wp3c-266w-4qfq)

high Tenable Self-Hosted Container Security Plugin ID 444040

Description

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

 - js-toml is a TOML parser for JavaScript, fully compliant with the TOML 1.0.0 Spec. Versions up to and
 including 1.1.0 parse hexadecimal / octal / binary integer literals via a hand-written `parseBigInt` loop
 that multiplies a `BigInt` accumulator by the radix once per input digit. Each iteration performs a
 `BigInt * BigInt` operation on an accumulator that grows linearly with the number of digits already
 consumed, so the whole loop is O(n²) in the literal length. The lexer regex places no upper bound on the
 literal length, so a single TOML document containing one ~500 kB hex literal pins one CPU core for ~40
 seconds on a modern laptop (Apple M-series, Node v22). Memory amplification is bounded but CPU
 amplification is severe and grows quadratically: doubling the literal length quadruples the work. A caller
 that invokes `load()` on attacker-controlled TOML (configuration upload endpoints, CI/CD systems ingesting
 third-party `*.toml`, IDE plugins, build tools) is exposed to a single-request CPU exhaustion DoS. Version
 1.1.1 fixes the issue. (CVE-2026-49293)

Solution

Update the js-toml library and its related packages to version 1.1.1 or later.
