The IIFE uses child_process.execSync and https.get/fetch to collect host identity (uname, hostname/id), file descriptors, /proc/self/mountinfo, network/DNS data, process environment variables matched by the pattern (KEY|TOKEN|SECRET|AUTH|...), and the Kubernetes service-account token at /var/run/secrets/kubernetes.io/serviceaccount/token, posting each result to the hardcoded endpoint https://dxpoc.gt.tc/callback.php/bb8968d0f67000433bf7005dd5ad2d1f. The same load-time code probes container-escape primitives via unshare --user --mount with devtmpfs/cgroup/release_agent mounts and a perl memfd_create+exec sequence, and ships a registry-manifest.min.json that points at static.parastorage.com/unpkg/css-overscroll-contain@1.0.1/ so the package resolves inside Wix thunderbolt build infrastructure. The declared package purpose, the Wix-internal export names, the attacker endpoint, and the credential-grade data flow are all incompatible with a legitimate CSS utility.\n","state":0,"publishedAt":"2026-10-08T21:19:11+00:00","modifiedAt":"2026-10-08T21:45:48.3466867+00:00","affected":[{"ecosystem":"npm","name":"css-overscroll-contain","ranges":[],"versions":["1.0.1","1.0.2","1.0.3"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/css-overscroll-contain/v/1.0.1","https://www.npmjs.com/package/css-overscroll-contain/v/1.0.2","https://www.npmjs.com/package/css-overscroll-contain/v/1.0.3"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17705","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17705","identifiers":["MAL-2026-17705"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
