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.

The 99.99.99 version is the standard dependency-confusion overshoot used to win resolution against an internal `@flexmr/ui`; any build that references that name will resolve this public package and execute the beacon. Publisher control of this scope slot additionally enables arbitrary future payloads to replace the current identity beacon.","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 @flexmr/ui (npm)","id":"MAL-2026-17879","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":[],"last_affected":[],"package":"@flexmr/ui","purl":"pkg:npm/%40flexmr/ui","source":"MAL-2026-17879"}],"products":null,"published":"2026-10-13","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-2026-17879/"}
