CVE-2026-55115 is a critical server-side request forgery (SSRF) vulnerability in the UniFi Protect Application. According to the provided content, a malicious actor with network access and low privileges can exploit the flaw to induce the application to make unintended server-side requests, resulting in privilege escalation on the host device. The vulnerability affects UniFi Protect version 7.1.77 and earlier and is fixed in version 7.1.83. Some provided reporting also associates the issue with a CORS misconfiguration and abuse of a victim’s authenticated session to perform unauthorized actions; however, the most consistent characterization in the supplied material is SSRF leading to privilege escalation.
