Progress ShareFile pre-auth RCE chain disclosed - 30,000 instances exposed, ransomware gangs watching (CVE-2026-2699, CVE-2026-2701)

Two flaws in Progress ShareFile's Storage Zones Controller can be chained for unauthenticated remote code execution - no credentials needed. An attacker first bypasses authentication via improper HTTP redirect handling, then uploads a malicious webshell through the file upload function. watchTowr published full technical details and a proof-of-concept. Around 30,000 instances are exposed online. File transfer solutions are a favorite ransomware target - Clop hit Accellion, GoAnywhere, MOVEit, and Cleo the same way.

Check
Check if you run Progress ShareFile with customer-managed Storage Zones Controller on branch 5.x.
Affected
ShareFile Storage Zones Controller 5.x versions prior to 5.12.4. Cloud-only ShareFile deployments are not affected.
Fix
Update to ShareFile Storage Zones Controller 5.12.4 or later (released March 10). Audit web server logs for requests to /ConfigService/Admin.aspx. Check the webroot for unexpected ASPX files that could indicate existing compromise.

Fortinet FortiClient EMS SQL injection actively exploited - no authentication required (CVE-2026-21643)

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.

Check
Check if you run FortiClient EMS with its web interface exposed to the internet.
Affected
FortiClient EMS 7.4.4 with multi-tenant mode enabled. Single-site deployments are not affected.
Fix
Upgrade to FortiClient EMS 7.4.5 or later. Restrict access to the EMS administrative interface immediately.

F5 BIG-IP APM flaw reclassified from DoS to pre-auth RCE - now actively exploited (CVE-2025-53521)

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.

Check
Check if you run F5 BIG-IP with APM access policies enabled.
Affected
BIG-IP APM 17.5.0-17.5.1, 17.1.0-17.1.2, 16.1.0-16.1.6, 15.1.0-15.1.10.
Fix
Update to 17.5.2, 17.1.3, 16.1.7, or 15.1.11 respectively. CISA deadline is March 30, 2026.

Langflow AI platform RCE exploited within 20 hours of disclosure - no auth required (CVE-2026-33017)

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.

Check
Check if you run Langflow, especially any instances exposed to the internet.
Affected
Langflow <= 1.8.1.
Fix
Upgrade to Langflow 1.9.0. If you can't patch now, take instances offline or block the /api/v1/build_public_tmp endpoint.

Oracle emergency patch for pre-auth RCE in Identity Manager and Web Services Manager (CVE-2026-21992)

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.

Check
Check if you run Oracle Identity Manager or Oracle Web Services Manager.
Affected
Oracle Identity Manager 12.2.1.4.0 and 14.1.2.1.0. Oracle Web Services Manager 12.2.1.4.0 and 14.1.2.1.0.
Fix
Apply the out-of-band Security Alert patch from Oracle immediately. Only available for versions under Premier or Extended Support.
