High CVSS 7.5
CVE-2026-55113
A malicious actor with access to the network could exploit a Server-Side Request Forgery (SSRF) vulnerability found in UniFi Talk Application to execute a Denial of Service (DoS) attack and bypass authentication in certain UniFi Talk API endpoints.
What this means
- Exposure
- Exploitable remotely over the network, without authentication and with no action from the victim. The attack does require particular conditions, which makes it less systematic.
- Impact
- An attacker can alter some data and take the service offline. The impact spreads beyond the vulnerable component into other parts of the system.
- Weakness
- The server issues a request to an attacker-chosen address, reaching into the internal network (SSRF).
- Likelihood
- Its EPSS score stays low: nothing points to imminent exploitation, which is no reason to leave it unpatched.
What to doFold into the next patch cycle. Start with the instances exposed to the internet.
