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.
