Why now
- Cisco vulnerability is already under active exploitation despite requiring credentials.
- Langflow attacks continue months after a patch, highlighting slow adoption of fixes.
- Both issues underscore the urgency of timely patching in critical infrastructure and AI platforms.
Why it matters
- Exploitation of these vulnerabilities can lead to full system compromise and root-level access.
- Cisco SD-WAN Manager is widely deployed in enterprise networks, increasing potential impact.
- Langflow's default disabled login exposes thousands of internet-facing instances to attack.
