This medium-severity CVE scores 6.9 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.3%, top 80% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

An information disclosure vulnerability in the SAML Single Sign-On (SSO) functionality of Omada Controller allows an authenticated user with SAML configuration privileges to access sensitive information due to insufficient validation of user-supplied SAML metadata. Successful exploitation could result in unauthorized disclosure of sensitive information.
