AI Analysis

Impact

The vulnerability resides in the Composer component of Oracle WebCenter Portal and can be triggered by an unauthenticated attacker through the portal’s HTTP interface. Exploitation requires a human interaction from a person other than the attacker, after which the attacker can take full control of the portal, compromising confidentiality, integrity, and availability. The flaw is an improper authorization weakness (CWE-284).

Affected Systems

Oracle WebCenter Portal versions 12.2.1.4.0 and 14.1.2.0.0 are affected as documented in the Oracle Security Alert CSPUSEP2026. No other versions are reported vulnerable.

Risk and Exploitability

The CVSS v3.1 base score of 9.6 classifies the vulnerability as critical, yet the EPSS score of < 1% indicates a low likelihood of exploitation in the near term. The vulnerability is not listed in CISA’s KEV catalog. Successful attacks would need network access to the portal’s public HTTP endpoint and require a victim to interact with the malicious payload to succeed.
