CVE-2026-22447 identifies a missing authorization vulnerability in the Select-Themes Prowess software, specifically affecting versions up to and including 1.8.1. The vulnerability arises from incorrectly configured access control security levels, allowing unauthorized remote attackers to access certain functionalities or data without any authentication or user interaction. The CVSS 3.1 base score is 5.3, reflecting a medium severity primarily due to its impact on confidentiality (partial data disclosure) without affecting integrity or availability. The attack vector is network-based with low attack complexity, and no privileges or user interaction are required, making exploitation feasible in environments where the vulnerable software is exposed. Although no known exploits have been reported in the wild, the lack of patches at the time of publication increases the risk window. The vulnerability could be leveraged to gain unauthorized read access to sensitive information managed by Prowess, potentially leading to data leakage or reconnaissance for further attacks. The issue is rooted in access control misconfigurations, which are critical security controls that prevent unauthorized access to resources. Organizations relying on Prowess should consider this vulnerability a priority for review and remediation once patches become available.

For European organizations, the primary impact of CVE-2026-22447 is the potential unauthorized disclosure of sensitive information due to missing authorization controls in Prowess. This can lead to confidentiality breaches affecting customer data, internal documents, or configuration details. While the vulnerability does not compromise data integrity or system availability, the exposure of confidential information can have regulatory consequences under GDPR and damage organizational reputation. Sectors such as finance, healthcare, and government, which often handle sensitive data and may use Select-Themes products, could face increased risks. Additionally, attackers might use the information gained to facilitate further targeted attacks or social engineering campaigns. The medium severity score suggests a moderate risk, but the ease of exploitation without authentication means that organizations with externally accessible Prowess instances are particularly vulnerable. The absence of known exploits currently provides a window for proactive mitigation, but this could change rapidly once exploit code is developed.

1. Immediately audit all Prowess installations to identify versions up to 1.8.1 and assess exposure, especially those accessible from external networks. 2. Implement strict network segmentation and firewall rules to restrict access to Prowess management interfaces to trusted internal IPs only. 3. Enforce strong access control policies and review user permissions to minimize potential unauthorized access. 4. Monitor logs and network traffic for unusual access patterns or attempts to access restricted functionalities without authentication. 5. Engage with Select-Themes for timely updates and apply patches as soon as they are released. 6. Consider deploying Web Application Firewalls (WAFs) with custom rules to detect and block exploitation attempts targeting this vulnerability. 7. Conduct security awareness training for administrators managing Prowess to recognize and respond to suspicious activities. 8. If possible, temporarily disable or restrict vulnerable features until a patch is available. 9. Maintain an incident response plan tailored to handle potential data breaches resulting from this vulnerability.
