CVE-2023-33181Network attack vector

Server path disclosure via API stack traces

Published May 30, 2023 · Updated Jan 9, 2025

Information exposure in Xibo CMS 3.0.0 through 3.3.4 allows attackers to learn server paths via API requests with invalid parameters. When affected API routes receive missing or invalid parameters, their error handling returns a stack trace rather than a sanitized error response. The disclosure is limited to server path information; the public advisory does not identify the routes or state whether authentication is required.
