Impact

A broken access control flaw in CSZ CMS 1.3.2 allows an unauthenticated attacker to read every submission in the admin form‑submission viewer. The viewer endpoint does not perform an authentication check and the framework’s authentication helper fails open, providing direct access to personally identifiable information without credentials. This weakness corresponds to CWE‑284 and results in disclosure of sensitive data to anyone who can reach the web interface.

Affected Systems

The vulnerability affects CSZ CMS, specifically version 1.3.2. No other vendor or product versions are listed as impacted.

Risk and Exploitability

The CVSS score of 7.5 indicates a significant risk. The EPSS score is not available, but the vulnerability is not listed in CISA KEV, suggesting it has not yet been widely exploited. An attacker can exploit this flaw remotely by sending HTTP requests to the viewer endpoint, which lacks any authentication or authorization checks. With no credentials required, the scope is system‑wide data disclosure, and the impact on confidentiality is high.
