CVE-2026-25928 — OpenEMR is a free and open source electronic health records and medical practice management application

Medium CVSS 6.5

OpenEMR is a free and open source electronic health records and medical practice management application. Prior to 8.0.0.2, the DICOM zip/export feature uses a user-supplied destination or path component when creating the zip file, without sanitizing path traversal sequences (e.g. `../`). An attacker with DICOM upload/export permission can write files outside the intended directory, potentially under the web root, leading to arbitrary file write and possibly remote code execution if PHP or other executable files can be written. Version 8.0.0.2 fixes the issue.

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
