Barracuda Flaws Could Be Chained to Bypass Authorization and Gain Root
Barracuda disclosed two vulnerabilities in its products: a pre-authentication authorization bypass and a command injection flaw. Chained together, they allow root access on an affected device, according to The Hacker News. One flaw is CVE-2026-116606, CVSS 9.3; the source gives no fix, so administrators should track vendor advisories and patch when available.
What happened
Barracuda disclosed two flaws in its security products. Chained together, they let an attacker bypass authorization controls without credentials and gain root access, full control of the device. One flaw carries a risk score of 9.3 out of 10 (CVE-2026-116606).
Why it matters
A compromised device means total administrative control by an attacker: the appliance can be used to monitor traffic, pivot into the internal network, and keep persistent access. Companies running Barracuda products at the network edge face critical exposure.
What to do
Inventory which Barracuda devices the company runs and where they are exposed. Track official vendor advisories and apply updates as soon as they ship; meanwhile, restrict management access to these appliances to internal networks.
