CVE-2026-24548 is a Server-Side Request Forgery (SSRF) vulnerability identified in the Prince Radio Player software, specifically affecting versions up to and including 2.0.91. SSRF vulnerabilities occur when an attacker can manipulate a server-side application to send HTTP requests to arbitrary domains or IP addresses, often leading to unauthorized internal network access or data leakage. In this case, the vulnerability allows unauthenticated attackers to craft requests that the server will execute, potentially accessing internal services that are otherwise inaccessible externally. The CVSS 3.1 base score of 5.3 reflects a medium severity, primarily due to the vulnerability's impact on confidentiality (limited data exposure) without affecting integrity or availability. The attack vector is network-based, requiring no privileges or user interaction, which increases the risk of exploitation. However, no known exploits have been reported in the wild so far. The lack of available patches at the time of disclosure means organizations must rely on interim mitigations. SSRF can be leveraged for internal reconnaissance, accessing metadata services, or pivoting to other internal systems, making it a significant concern in environments where Prince Radio Player is deployed. The vulnerability affects the radio-player component of the Prince software suite, commonly used in media streaming and broadcasting contexts.

For European organizations, the SSRF vulnerability in Prince Radio Player could lead to unauthorized internal network scanning and potential exposure of sensitive internal services or data. Media companies and broadcasters using this software might inadvertently allow attackers to access internal APIs, configuration endpoints, or cloud metadata services, which could facilitate further attacks or data breaches. Although the vulnerability does not directly compromise data integrity or system availability, the confidentiality impact could lead to leakage of sensitive information, such as internal IP addresses, service configurations, or authentication tokens. This risk is heightened in complex network environments with segmented internal services. Additionally, exploitation could serve as a foothold for attackers to escalate privileges or move laterally within the network. Given the medium severity and no authentication requirement, the threat is relevant for organizations with exposed Prince Radio Player instances, especially those lacking strict outbound request controls or input validation.

1. Monitor Prince vendor communications closely and apply security patches promptly once released to address CVE-2026-24548. 2. Implement strict outbound network filtering on servers running Prince Radio Player to restrict HTTP requests only to trusted external endpoints, blocking internal IP ranges and sensitive services. 3. Employ input validation and URL allowlisting within the application to ensure only legitimate, expected URLs are processed, preventing attacker-controlled request redirection. 4. Conduct internal network segmentation to limit the exposure of critical services that could be targeted via SSRF. 5. Enable detailed logging and monitoring of outbound HTTP requests from the radio player server to detect anomalous or suspicious activity. 6. If patching is delayed, consider temporary disabling or restricting features that accept user-supplied URLs or external resource requests. 7. Educate security and IT teams about SSRF risks and detection techniques to improve incident response readiness.
