The published tarball contains no install scripts and no network code; the payload lives in the private dependency, which was not retrieved. Twenty-six such packages under seventeen accounts were published between 2026-07-28 and 2026-10-09.","summary":null,"severity":"critical","cvss":null,"epss":null,"exploited":false,"exploited_at":null,"products":[{"name":"tailwind-css-keyframes","fixed":[],"affected":"= 1.0.7","ecosystem":"npm"}],"ecosystems":["npm"],"tags":["malicious","package"],"not_affected_if":[],"how_to_check":null,"fix":null,"status":"open","published_at":"2026-10-19T00:00:00+00:00","first_seen_at":"2026-10-26T20:51:48+00:00","triaged_at":"2026-10-26T21:06:18+00:00","updated_at":"2026-10-26T21:06:18+00:00","category":"package","confidence":null,"triage":null,"analyst_status":null,"analyst_note":null,"search":"'-07':141C '-09':59C,146C '-10':145C '-17665':40C '-17666':44C '-18081':11A,14A '-2026':10A,13A,39C,43C '-28':60C,142C '1.0.7':25C '2026':58C,140C,144C '5':62C 'account':136C 'animate.css':47C 'badu':56C 'behind':37C 'campaign':36C 'code':2A,93C,117C 'commit':84C 'contain':110C 'css':6A,17A,23C,29C 'deliv':95C 'depend':124C 'descript':52C 'dev':104C 'fake':33C 'instal':112C 'integr':48C 'interview':35C 'jasperquinn/postcss-motion-helpers':68C 'job':34C 'keyfram':7A,24C 'keyframes':18A 'kinsley':55C 'live':120C 'load':99C 'lure':87C 'mal':9A,12A,38C,42C 'malici':1A,19B 'network':116C 'npm':8A,82C 'packag':20B,67C,133C 'payload':119C 'plugin':30C,101C 'privat':65C,123C 'public':75C 'publish':53C,108C,138C 'readabl':72C 'readm':50C 'registri':76C 'repositori':88C 'requir':63C 'resolv':78C 'retriev':128C 'run':96C 'scope':66C 'script':113C 'server':105C 'seventeen':135C 'six':131C 'src/motion.js':61C 'start':106C 'tailwind':5A,16A,22C,28C 'tailwind-css-keyfram':4A,21C 'tailwind-css-keyframes':15A 'tailwind.config.js':98C 'tarbal':109C 'templat':49C 'token':83C 'twenti':130C 'twenty-six':129C 'web/.npmrc':90C","nicknames":[],"mitigations":[],"who_affected":null,"tier":null,"verified":{},"analyst_revisit_at":null,"first_public_at":"2026-10-19T00:00:00+00:00","kev":null,"cvss_vector":null,"cvss_by":null,"poc_count":0,"sources":[{"source":"osv-malicious","external_id":"MAL-2026-18081","url":"https://osv.dev/vulnerability/MAL-2026-18081","severity":"critical","published_at":"2026-10-19T00:00:00+00:00","modified_at":"2026-10-20T06:15:06+00:00","first_seen_at":"2026-10-26T20:51:48+00:00","fetched_at":"2026-10-26T20:51:48+00:00","note":null}],"documents":[],"notice":"Free to read at a human pace.
