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.

No exfiltration, dropper, or attacker-controlled network destination is reachable in the shipped artifact. Separately, the published name `react-editable-calendar` does not match the library's documented identity (`schedulaforge`, exporting a `SchedulaForge` class) and the package contains no React-specific code; the chosen name appears positioned to attract developers searching for a React calendar component. Together these signals — a dangling preinstall pointer to a non-shipped script in a headless library, plus a name/identity mismatch — are atypical enough to warrant human review of the maintainer's intent, but the artifact as published does not harm installers.\n\nThe OpenSSF Package Analysis project identified 'react-editable-calendar' @ 0.1.7 (npm) as malicious.\n\nIt is considered malicious because:\n\n- The package executes one or more commands associated with malicious behavior.","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 react-editable-calendar (npm)","id":"MAL-2026-6547","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":"react-editable-calendar","purl":"pkg:npm/react-editable-calendar","source":"MAL-2026-6547"}],"products":null,"published":"2026-06-27","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-2026-6547/"}
