Rails Active Storage Flaw Turns Image Uploads Into a Secret-Rotation Drill
Rails maintainers patched CVE-2026-66066, a critical Active Storage flaw that can let attackers turn image uploads into arbitrary file reads and possible remote code execution. For affected teams, the job is not only upgrading Rails and libvips, but checking exposure windows and rotating secrets that may have been readable by the Rails process.
Chrome’s AI Bug Surge Makes Browser Restarts a Security Deadline
Google says Chrome 149 and 150 fixed 1,072 security bugs, more than the prior 23 milestones combined, as AI-assisted vulnerability discovery accelerates. The result is a push toward twice-weekly security releases, dynamic patching, and stricter enterprise browser-restart policies.
SourTrade Malvertising Makes Browsers Build Malware in Memory
Confiant says the SourTrade malvertising campaign impersonates TradingView, Solana, and Luno, then uses service workers and shared workers to make a victim’s browser assemble a unique Windows malware file in memory. The technique weakens hash-based detection and gives crypto users another reason to avoid sponsored-download paths.
Check Point SmartConsole Zero-Day Puts Firewall Management on Patch Deadline
Check Point has patched CVE-2026-16232, an actively exploited SmartConsole authentication bypass that can give attackers full administrator access to exposed Security Management servers.

Zoom has patched CVE-2026-53412, a critical Windows client flaw that could let an unauthenticated attacker take over accounts over the network. The practical response is to verify Zoom Workplace and VDI client versions, not just assume auto-update has reached every endpoint.
Russian Router Campaign Turns SNMP Into a Critical Infrastructure Risk
NSA, CISA, the FBI, and 15 allied agencies warn that Russian FSB Center 16 actors are still compromising poorly configured routers across critical infrastructure. The practical fix starts with SNMPv3, blocked management protocols, patched firmware, and a hard look at exposed network devices.
SharePoint’s New Exploited RCE Turns Patching Into Key Rotation Triage
CISA added Microsoft SharePoint Server CVE-2026-58644 to its exploited-vulnerabilities catalog on July 16, two days after Microsoft patched it. Admins should patch, verify AMSI, hunt for machine-key theft, and reduce internet exposure before treating the farm as clean.
CMS Webshell Campaign Puts WordPress Plugins on an Emergency Checklist
Australia's cyber agency says attackers are exploiting known CMS and plugin flaws at scale to plant webshells on public websites. Site owners should treat this as a compromise check, not just a routine update reminder.
Microsoft Purview Migration Puts Defender DLP Policies on a Deadline
Microsoft is retiring Defender for Cloud Apps file policies on January 6, 2027, forcing Microsoft 365 security teams to rebuild DLP and auto-labeling controls in Purview before existing policies stop being supported or enforced.
