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.
A flaw in Smart Slider 3 - one of WordPress's most popular slider plugins with over 800,000 active installations - lets anyone with a basic subscriber account download arbitrary files from the server. That includes wp-config.php, which contains database credentials, encryption keys, and salt data. An attacker only needs the lowest level of authenticated access to trigger the vulnerable export function and package sensitive files into a downloadable ZIP.
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 are scanning internet-facing Citrix NetScaler ADC and Gateway appliances right now, probing the /cgi/GetAuthMethods endpoint to find which ones are configured as SAML identity providers - the exact setup needed to trigger this CVSS 9.3 memory-leak flaw. Not full exploitation yet, but researchers at watchTowr warn the jump from recon to attack could happen any day.
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.
Oracle broke its quarterly patch cycle to push an emergency fix for CVE-2026-21992 - a CVSS 9.8 pre-auth RCE in Oracle Identity Manager and Web Services Manager. An unauthenticated attacker with network access over HTTP can take over the entire identity management system. Oracle won't say if it's been exploited, but a nearly identical flaw in the same product (CVE-2025-61757) was added to CISA's KEV catalog just four months ago.
