Do not edit below this line.=-_\n\n## Source: amazon-inspector (20ab57dd6ac5a0eafc23934f6e715064453641bc57a549050f1d2e66a7630374)\npackage.json declares its sole dependency `cache-format-syntax-tracer` as a bare HTTPS URL (`https://artifacts.creditslib.com/npm/cache-format-syntax-tracer`) rather than a registry version range. On `npm install`, npm fetches whatever bytes that host serves and executes any lifecycle scripts inside, with no version pin, no registry integrity check, and no hash. The shipped `index.js` is a one-line re-export of that dependency, so runtime behavior is also fully delegated to the externally-hosted bytes. Whoever controls `artifacts.creditslib.com` controls code on every installer's machine, and the content can change between installs without any change to this package. The package is published under the `@flexmr` scope with placeholder author/publisher metadata (`example/@flexmr/...`, `Package Registry`), consistent with a dependency-confusion lure targeting an internal `@flexmr` package name.\n\n## Source: ghsa-malware (b8f042afac9d9ae3889355bedbbe09987373e982aa49ccbc8a4bfceb8bc28416)\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.","summary":null,"severity":"critical","cvss":null,"epss":null,"exploited":false,"exploited_at":null,"products":[{"name":"@flexmr/survey-conversation","fixed":[],"affected":"all versions","ecosystem":"npm"}],"ecosystems":["npm"],"tags":["malicious","package"],"not_affected_if":[],"how_to_check":null,"fix":null,"status":"open","published_at":"2026-10-16T06:55:02+00:00","first_seen_at":"2026-10-27T17:03:02+00:00","triaged_at":"2026-10-27T17:04:52+00:00","updated_at":"2026-10-27T17:04:52+00:00","category":"package","confidence":null,"triage":null,"analyst_status":null,"analyst_note":null,"search":"'-17899':13A '-2026':12A '/npm/cache-format-syntax-tracer':53C '20ab57dd6ac5a0eafc23934f6e715064453641bc57a549050f1d2e66a7630374':35C 'also':105C 'amazon':33C 'amazon-inspector':32C 'artifacts.creditslib.com':52C,116C 'artifacts.creditslib.com/npm/cache-format-syntax-tracer':51C 'author/publisher':147C 'b8f042afac9d9ae3889355bedbbe09987373e982aa49ccbc8a4bfceb8bc28416':170C 'bare':48C 'behavior':103C 'byte':66C,113C 'cach':42C 'cache-format-syntax-trac':41C 'chang':128C,133C 'check':83C 'code':2A,118C 'compromis':184C 'comput':172C,192C,200C,212C 'confus':158C 'consid':182C 'consist':153C 'content':126C 'control':115C,117C,209C 'declar':37C 'deleg':107C 'depend':40C,100C,157C 'dependency-confus':156C 'detail':24C 'differ':199C 'edit':27C 'entiti':220C 'everi':120C 'exampl':149C 'execut':71C 'export':97C 'extern':111C 'externally-host':110C 'fetch':64C 'flexmr':143C,150C,163C 'flexmr/survey-conversation':4A,19A 'format':43C 'fr74':10A,18A 'full':208C 'fulli':106C,183C 'ghsa':7A,15A,168C 'ghsa-hc8w-gq4q-fr74':6A,14A 'ghsa-malwar':167C 'given':216C 'gq4q':9A,17A 'guarante':224C 'hash':86C 'hc8w':8A,16A 'host':68C,112C 'https':49C 'immedi':196C 'index.js':89C 'insid':75C 'inspector':34C 'instal':62C,121C,130C,177C,236C 'integr':82C 'intern':162C 'key':188C 'lifecycl':73C 'line':30C,94C 'lure':159C 'machin':123C 'mal':11A 'malici':1A,20B,232C 'malwar':169C 'may':213C 'metadata':148C 'name':165C 'npm':5A,61C,63C 'one':93C 'one-lin':92C 'outsid':219C 'packag':21B,136C,138C,151C,164C,176C,202C,228C 'package.json':36C 'per':22C 'pin':79C 'placehold':146C 'publish':140C 'rang':59C 'rather':54C 're':96C 're-export':95C 'registri':57C,81C,152C 'remov':205C,226C,230C 'result':234C 'rotat':195C 'run':179C 'runtim':102C 'scope':144C 'script':74C 'secret':186C 'serv':69C 'ship':88C 'softwar':233C 'sole':39C 'sourc':23C,31C,166C 'store':189C 'syntax':44C 'target':160C 'tracer':45C 'url':50C 'version':58C,78C 'whatev':65C 'whoever':114C 'without':131C","nicknames":[],"mitigations":[],"who_affected":null,"tier":null,"verified":{},"analyst_revisit_at":null,"first_public_at":"2026-10-16T06:55:02+00:00","kev":null,"cvss_vector":null,"cvss_by":null,"poc_count":0,"sources":[{"source":"osv-malicious","external_id":"MAL-2026-17899","url":"https://osv.dev/vulnerability/MAL-2026-17899","severity":"critical","published_at":"2026-10-16T06:55:02+00:00","modified_at":"2026-10-27T16:30:05+00:00","first_seen_at":"2026-10-27T17:03:02+00:00","fetched_at":"2026-10-27T17:03:02+00:00","note":null}],"documents":[],"notice":"Free to read at a human pace.
