CVE-2025-60946Public exploitNetwork attack vector

Authenticated file disclosure via unsanitized path resolution

Published Mar 23, 2026 · Updated Mar 23, 2026

Path traversal in U.S. Census Bureau CSWeb 8.0.1 allows remote authenticated users to read arbitrary server-side files via crafted path input. The public record does not identify the affected endpoint or function; CSWeb resolves unsanitized paths containing traversal sequences outside the intended directory. A valid CSWeb account is required, and disclosure is limited to files readable by the web-service process.
