CVE-2026-25525Public exploitNetwork attack vector

Administrator file disclosure via single-pass path filtering

Published Apr 20, 2026 · Updated Apr 20, 2026

Path traversal in OpenMage LTS before 20.17.0 allows remote authenticated users with administrator access to read server files. The CSV and Excel XML Dataflow parsers apply a single str_replace pass to the decoded files parameter, so nested traversal patterns collapse into ../ after filtering. Administrator access to a Dataflow profile is required, and successful exploitation exposes files readable by the web-server account without altering them.
