OpenEMR < 8.3.0 Path Traversal Information Disclosure via EDI Archive Restore

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

OpenEMR before 8.3.0 contains a path traversal vulnerability in the EDI archive restore function. The archrestore_sel POST parameter is passed to the archive restore handler without sanitization for path traversal sequences. The handler checks whether the supplied path exists on the filesystem, and the differing response messages leak whether the target path exists. An authenticated user with EOB Data Entry permissions can probe arbitrary filesystem paths on the server to determine file existence.
