- CISA lists CVE-2026-15409 and CVE-2026-15410 as exploited in the wild.
SonicWall disclosed two vulnerabilities affecting its SMA 1000 series Secure Mobile Access appliances (models 6210, 7210, and 8200v) on July 14, 2026. CVE-2026-15409 is a critical unauthenticated server-side request forgery (SSRF) flaw, while CVE-2026-15410 allows an authenticated administrator to achieve remote code execution. SonicWall confirmed both vulnerabilities are being actively exploited in the wild, though it has not clarified whether an unauthenticated attacker could chain the two flaws to gain full control of an affected device.
SonicWall has published indicators of compromise for defenders to search their logs. Critically, the vendor states that if any of these indicators are found, simply applying the patch is insufficient — affected organizations must fully reinstall the system, rotate all user and administrator passwords, and reset TOTP-based one-time password seeds. The French CERT-FR has issued an alert directing organizations to SonicWall's advisory (SNWLID-2026-0008) for patches and remediation guidance.
Given the active exploitation of an unauthenticated SSRF vulnerability in an internet-facing remote access product, affected organizations should treat this as an urgent patching and compromise-assessment priority, following the vendor's full remediation steps rather than patching alone.

What this brief leaves out
This page is the free tier: the write-up, the severity, the names. In the app the same report carries live profiles of the CVEs it names. The paid plans add the security research and news reporting the free tier leaves out.
It sits in a corpus of 16,445 reports from 149 sources, 666 of them written in the last seven days, and it grows through the day.
A new account starts with three days of all of it, no card, then keeps the government and CERT reporting free. Slack alerts are a paid-plan feature: name the vendors you run and Slack hears about the reports that touch them, not the rest of the week's. Nothing is charged unless you subscribe.
