CVE-2025-54141 | ViewVC's standalone server exposes arbitrary server filesystem content

Exp

ViewVC is a browser interface for CVS and Subversion version control repositories. In versions 1.1.0 through 1.1.31 and 1.2.0 through 1.2.3, the standalone.py script provided in the ViewVC distribution can expose the contents of the host server's filesystem though a directory traversal-style attack. This is fixed in versions 1.1.31 and 1.2.4.
