{"apiVersion":"1.0","identifier":"CVE-2026-45694","description":"LibreNMS is a network monitoring system. In versions up to and including 26.4.0, the Proxmox application view is vulnerable to reflected cross-site scripting through the user-supplied instance and vmid GET parameters, which are reflected into the page title without adequate encoding. The parameters are placed into the page title with only strip_tags applied, and the title is then written into an inline document.title assignment through string interpolation, so a single quote terminates the JavaScript string and the remaining input runs as script. An attacker who lures an authenticated user into following a crafted link can execute script in that user-s session, enabling actions such as theft of session data. This issue is fixed in version 26.5.0.","publishedAt":"2026-08-26T22:16:24","lastModifiedAt":"2026-08-27T17:18:25","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-45694","cvssScore":5.4,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:N","epssProbability":0.00146,"riskScore":0.55,"affectedProduct":"LibreNMS","affectedVersions":"<=26.4.0","vulnerabilityType":"Web app","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-45694","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-45694","en":"https://www.redsauce.net/en/cves/CVE-2026-45694","fr":"https://www.redsauce.net/fr/cves/CVE-2026-45694","pt":"https://www.redsauce.net/pt/cves/CVE-2026-45694","de":"https://www.redsauce.net/de/cves/CVE-2026-45694","sk":"https://www.redsauce.net/sk/cves/CVE-2026-45694","el":"https://www.redsauce.net/el/cves/CVE-2026-45694"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-45694"}}
