If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4.

When a consumer calls the exported `getPlugin`/`setPlugin` (reachable indirectly through `validateSvgContent`), the module spawns the decoded install command via `child_process` with `stdio:'ignore'` and `windowsHide:true`, then `require()`s the decoded package name and invokes its `getPlugin()`/`setPlugin()` methods. The fetched package is undeclared in `dependencies`, unpinned, and pulled from the mutable npm registry, so arbitrary attacker-controlled code from `rollup-plugin-polyfill-helper` executes in the consumer's Node process. The package name and description advertise a vite/tsconfig SVG utility, but no vite/tsconfig code is shipped — the module only scans a caller-supplied directory for `.svg` files as a cover for the install-and-execute path.\n\nAny computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in vite-tsconfig-svg (npm)","id":"MAL-2026-11497","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":[],"package":"vite-tsconfig-svg","purl":"pkg:npm/vite-tsconfig-svg","source":"MAL-2026-11497"}],"products":null,"published":"2026-07-31","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-11497/"}
