Check Point uncovered Operation TrueChaos - a Chinese-nexus espionage campaign that turned a video conferencing platform's update mechanism into a malware delivery system. The attackers compromised a central on-premises TrueConf server used by a government IT department, then swapped the legitimate client update with a weaponized package that deployed the Havoc post-exploitation framework. Every connected government agency pulled the poisoned update automatically, no individual endpoint compromise needed.
A CVSS 9.1 SQL injection flaw in Fortinet's FortiClient Endpoint Management Server is now being exploited in the wild - four days before anyone flagged it publicly. An attacker only needs one crafted HTTP request with a malicious Site header to execute arbitrary SQL against the backing PostgreSQL database, no credentials required. Roughly 1,000 to 2,400 FortiClient EMS instances are exposed to the internet, mostly in the US and Europe.
The Citrix NetScaler flaw we reported under active recon two days ago has escalated fast. Attackers are now sending crafted SAMLRequest payloads that trigger memory leaks exposing sensitive data through session cookies. CISA added CVE-2026-3055 to the Known Exploited Vulnerabilities catalog on March 30 with an unusually tight April 2 remediation deadline - just three days for federal agencies.
Remember that F5 BIG-IP APM bug from last year everyone treated as a denial-of-service issue? Turns out it's pre-auth remote code execution - CVSS 9.3. F5 quietly reclassified it after new findings in March 2026 and confirmed exploitation in the wild. CISA added it to the KEV catalog with a March 30 patch deadline. That's tomorrow.
Attackers didn't wait for a proof-of-concept. Within 20 hours of CVE-2026-33017 being disclosed in Langflow - an open-source AI workflow builder with 145K+ GitHub stars - they built working exploits straight from the advisory. One crafted HTTP POST to the public flow endpoint is all it takes, no credentials needed. Compromised instances leak API keys for OpenAI, AWS, and connected databases.
