The advisory currently has no npm package mapping or affected/patched version information, although the upstream project provides enough information to determine these values.
The affected project is the npm package
npm-check-updates.The advisory states that versions through 23.0.2 are affected. Upstream PR #1994, "Strip terminal escape sequences from package and registry text", was merged as commit b554b84848fc0b08a9d2b3d3db15e351387168cf.
The upstream
v23.1.0tag contains this fix commit, and its package.json identifies the released package asnpm-check-updatesversion23.1.0.Therefore the advisory should record:
I have also added the tagged v23.1.0 package.json as supporting upstream release evidence.
The existing CVSS v4 vector also contains unsupported supplemental/environmental metrics that the GitHub advisory editor cannot parse. I normalized it to the CNA-published CVSS v4 base vector:
CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:NThis preserves the published 5.3 Moderate base score.
