| CVE | Summary | Source | Max CVSS | EPSS % | Published | Updated |
|---|---|---|---|---|---|---|
| CVE-2023-7312 | Nagios Fusion versions prior to 4.2.0 contain a stored cross-site scripting (XSS) vulnerability when adding or configuring Email Settings. Unsanitized user input can be stored and later rendered in the administrative UI, causing JavaScript to execute in the browser of any user who views the affected page. An attacker who can add or modify SMTP/email settings or manipulate the sendmail configuration fields could persist a malicious payload that executes in the context of other users' browsers. | [email protected] | 6.2 | 0.48% | 2025-10-30 | 2025-11-06 |
| CVE-2023-53690 | Nagios Fusion versions prior to 4.2.0 contain a stored cross-site scripting (XSS) vulnerability in the LDAP/AD authentication-server configuration. Unsanitized user input can be stored and later rendered in the administrative UI, causing JavaScript to execute in the browser of any user who views the affected page. An attacker who can add authentication servers via LDAP/AD integration could persist a malicious payload that executes in the context of other users' browsers. | [email protected] | 6.2 | 1.23% | 2025-10-30 | 2025-11-06 |
| CVE-2023-53689 | Nagios Fusion versions prior to 4.2.0 contain a reflected cross-site scripting (XSS) vulnerability in the license key configuration flow that can result in execution of attacker-controlled script in the browser of a user who follows a crafted URL. While the application server itself is not directly corrupted by the reflected XSS, the resulting browser compromise can lead to credential/session theft and unauthorized administrative actions. | [email protected] | 6.0 | 0.17% | 2025-10-30 | 2025-11-06 |
