Part of the Cisco Meraki Security Hardening Release (October 2026, advisory cisco-sa-hardening-meraki-os-drbEX9GH, updated 9 November 2026): injection (improper neutralization) (CWE-74), CVSS 8.8. Affects Meraki MR access points, MS switches, MX security/SD-WAN appliances, MV cameras, MG cellular gateways and Campus Gateways regardless of configuration. Found in Cisco's internal security review; not known to be exploited.
As part of Cisco's ongoing commitment to proactive security and product quality, the Cisco networking engineering team has conducted a comprehensive internal security review. This review resulted in software hardening releases that address multiple internally discovered vulnerabilities.
The vulnerabilities tracked by CVE-76472 are related to issues with improper neutralization of special elements that are grouped under the Common Weakness Enumeration (CWE) Pillar CWE-74.
Remediation
No workarounds. Upgrade to the first fixed release for each product line listed in Cisco advisory cisco-sa-hardening-meraki-os-drbEX9GH (e.g. MR 33.1.3 / 32.2.5, MS 18.1.9, MX 26.2.3 / 26.1.7, MV 8.0, MG 26.1.4, Campus Gateway 32.2.5; 33.1.4 due mid-November 2026). Some fixes are model-specific — check each device. Reef Sentinel analysis: https://www.reef-sentinel.net/n/216

Email settings
SMTP on ports 25/465/587 is blocked outbound by some hosts (e.g. DigitalOcean droplets by default) — Resend and Brevo send over their HTTPS API instead, so they work even then. Only the selected provider is used to send; the others stay saved but idle, so you can switch back any time without losing settings.
Get a key from resend.com/api-keys. Uses the "From address" below as the sender — it must be on a domain you've verified with Resend.
Get an API key (not an SMTP key) from app.brevo.com/settings/keys/api. Uses the "From address" below as the sender — it must be a verified sender in your Brevo account.
"From address" and "Site name/URL" are shared by SMTP, Resend, and Brevo — they control what recipients see, regardless of which provider is active.
Send a test email
Sends through whichever provider is currently active above. Save your settings first if you just changed them.
