What is MAL-2026-10206?

Official description
Package advertises itself as an SVG fetcher/sanitizer but its main module also exports an undocumented getPlugin() function. The returned function performs an HTTP request to https://www.jsonkeeper.com/b/3P9BF with a custom 'bearrtoken' header, parses the JSON response, and passes the 'model' field directly to eval(). jsonkeeper.com is a public, mutable, anonymous paste host — whoever controls the paste can change its contents at any time and thereby execute arbitrary JavaScript inside any consumer process that invokes the exported function. The hidden code path is inconsistent with the package's declared SVG-utility purpose and is the canonical shape of a supply-chain backdoor giving the paste operator remote code execution on downstream consumers.
What should I do about MAL-2026-10206?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
