Malicious code in consumerweb-authflow (npm)
--- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (acbd81f78a40f87b410799545f06c929bc7e7c3f552eeea06254416b3b9e0977) On `npm install`, the package's postinstall.js collects host identifiers via `os.hostname()`, `os.userInfo().username`, `os.platform()`, and the current working directory, then POSTs them over HTTPS to `kd1tbfhej84bcqde44rq77o79yfp3gr5.oastify.com` (a Burp Collaborator out-of-band callback subdomain). The package's own metadata self-identifies as a dependency-confusion proof-of-concept (`description: "Dependency confusion PoC - H1-lingtys"`, payload tag `src: 'paypal-dep-confusion-poc'`), and the package name is chosen to collide with an internal/private package name so that misconfigured resolvers pull this public version instead. Regardless of bug-bounty intent, every installer's machine identity is leaked to an external attacker-controlled OAST endpoint without consent, automatically, on a default install. ## Source: ossf-package-analysis (0a4795bc3b2c513417e92b1547d165f9b6cbb750f437b5bf3ac87e63832087ca) The OpenSSF Package Analysis project identified 'consumerweb-authflow' @ 4.1.1 (npm) as malicious.

For interim severity, fall back on KEV / EXPLOIT signals and the EPSS percentile (lower panel). Re-check this CVE after one cron tick — the score lands automatically when the source publishes.
FIRST.org publishes EPSS daily. Coverage isn't universal — pre-disclosure CVEs and reserved IDs don't carry an EPSS score until at least one exploitation signal lands. Score will appear within 24 hours of the next EPSS pull.
No exploitation, limited impact or prevalence
