DAILY BRIEFING
Microsoft: Windows Server 2022 reached end of mainstream support
Today's briefing covers an actively exploited Palo Alto Networks RCE flaw, critical Drupal core updates fixing an unauthenticated RCE path, and malware campaigns impersonating popular AI tools.

Active exploitation of network infrastructure and web application flaws highlights today's threat landscape. Palo Alto Networks has patched a high-severity PAN-OS flaw targeted in the wild, while Drupal released critical updates for a Field UI vulnerability enabling remote code execution. Meanwhile, threat actors are impersonating AI tools to distribute malware to corporate devices. Security teams managing perimeter firewalls and Drupal installations must prioritize patching immediately. Restricting firewall management interfaces to trusted jump boxes offers immediate mitigation while applying updates. Organizations should also enforce software installation controls to counter malicious AI downloads.
Drupal Patches Critical Core RCE Flaw with No-Login Path via Contributed Modules
Drupal released patches for a critical core remote code execution vulnerability (CVE-2026-108097) in the Field UI module. While core alone is not directly exploitable, multiple attack paths exist via contributed modules or custom code, including at least one unauthenticated exploit path.
- Why it matters
- Organizations running affected Drupal versions using vulnerable contributed modules risk complete server compromise by remote unauthenticated attackers.
- What to do
- Update Drupal core installations to versions 11.4.10, 11.3.19, or 10.6.19 depending on the active branch.
Palo Alto Networks Patches PAN-OS Authenticated RCE Flaw Amid Active Exploitation
Palo Alto Networks patched an actively exploited high-severity remote code execution vulnerability (CVE-2026-0322) in PAN-OS. The flaw allows authenticated attackers with network access to run arbitrary code with root privileges on management interfaces across PA-Series, VM-Series, and Panorama devices.
- Why it matters
- Active exploitation permits compromised users or malicious insiders to gain full root-level control over perimeter firewalls and central management consoles.
Fake AI Attacks Spread Across US Companies: How MSSPs Can Stop Incidents Early
Threat actors are impersonating popular AI products to distribute malware, hijack browser sessions, and breach corporate accounts. Research from ANY.RUN associated 1,258 public sandbox runs with fake AI campaigns between April and October 2026, targeting US businesses.
- Why it matters
- Employees downloading untrusted AI applications risk exposing corporate credentials and session tokens, placing additional triage burden on security operations.

Police arrests 95 suspects in international CSAM crackdown action
Law enforcement authorities from 17 countries in Latin America and Europe have arrested 95 suspects in an INTERPOL-coordinated operation targeting the distribution of child sexual abuse material (CSAM) through online messaging groups.
- Why it matters
- Details of the law enforcement operation and potential organizational impacts are unavailable in the source text.
Key takeaways
- Patch Palo Alto Networks PAN-OS firewalls and Panorama to fix CVE-2026-0322, an authenticated RCE flaw under active exploitation.
- Update Drupal installations to 11.4.10, 11.3.19, or 10.6.19 to address critical Field UI flaw CVE-2026-108097.
- Restrict access to PAN-OS management interfaces to trusted internal IP addresses or jump boxes to mitigate exploitation risks.
