Low risk8th percentile - higher than 8% of all known CVEs
Summary
A Link Following Local Privilege Escalation vulnerability in the RazerPhilipsHueUninstall module of Razer Synapse 3. An attacker must first obtain the ability to execute low-privileged code on the target system. The flaw exists within the Philips HUE module installer; by creating a symbolic link, an attacker can abuse the installer to delete arbitrary files.
Risk Assessment
A low-privileged attacker can escalate privileges and execute arbitrary code as SYSTEM, leading to full system compromise.
Recommendation
Update Razer Synapse 3 to a patched version and restrict the ability of local users to run untrusted code.
