MAL-2026-13622 Malicious code in @depup/astro (npm)

This package is published under the @depup scope but sets author to 'withastro' and repository to github.com/withastro/astro, framing itself as a routine dependency-bump of the upstream astro framework. Its package.json systematically replaces well-known astro dependencies with same-shape lookalike names controlled by different maintainers, including picocolors→piccolore (^0.1.3), debug→obug (^2.1.4), and @astrojs/markdown-remark→@astrojs/markdown-satteri (0.3.5), alongside other atypical names such as tinyclip, am-i-vibing, and fontace. The shipped source has been mass-rewritten to import from the lookalikes (e.g., import colors from "piccolore" in place of picocolors), so a normal npm install and subsequent build resolves and executes code from those lookalike packages rather than the genuine upstream dependencies. The advertised version numbers (astro 7.2.0, vite 8, esbuild 0.28, zod 4) do not correspond to real upstream releases, and README keywords like 'security', 'latest', and 'patched' are used to normalize the substitutions as a maintenance update.
