CVE-2026-83548
Description
A Pre-authentication SSRF vulnerability exists in the SMA1000 Appliance Work Place interface due to an unintended alternate access path. A remote unauthenticated attacker could potentially exploit this vulnerability to gain unauthorized access to sensitive functionality and perform unauthorized operations.
In plain language
AI Act nowCVE-2026-83548 is a serious security hole in SonicWall SMA1000’s “Work Place” interface that lets an attacker send the device to access other systems without logging in—so if your SMA1000 has Work Place enabled and is reachable, you should act immediately.
Unauthenticated SSRF in the SonicWall SMA1000 Appliance Work Place interface allows pre-auth network-triggered requests to arbitrary or restricted internal/unauthorized targets via an unintended alternate access path.
What to do now
- Check whether your SonicWall SMA1000 has the Work Place interface enabled.
- Check whether the SMA1000 is reachable from the internet on the Work Place-related network paths (external IPs/port forwarding/firewall rules/load balancers).
- If Work Place is enabled and the device is internet-reachable, treat this as actively exploited and apply SonicWall’s mitigations immediately; if no mitigation is available for your version, discontinue use until you can mitigate.
- Confirm your environment is updated to the fixed guidance provided by SonicWall for SMA1000; if no fixed version is available, implement the vendor’s stated compensating controls (and block/restrict external access to Work Place paths).
