EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
Description
Spring for GraphQL applications that have enabled the WebSocket transport are vulnerable to Cross-Site WebSocket Hijacking. An attacker can trick an authenticated user into visiting a malicious page, allowing the attacker to execute arbitrary GraphQL operations with the victim's credentials.
Affected versions: Spring for GraphQL 2.0.0 through 2.0.3; 1.4.0 through 1.4.5; 1.3.0 through 1.3.8; 1.0.0 through 1.0.6.
Affected Products

Vendor / applianceDetect
Inventory every vmware spring for graphql deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for exploitation at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.
Fix
Apply the vmware spring for graphql security patch or hotfix for CVE-2026-41700 on the affected version, following the vendor advisory for your exact build.
Workarounds
Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.
How O3 protects you
O3 detects and blocks CVE-2026-41700 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.
Tailored to CVE-2026-41700. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is CVE-2026-41700 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2026-41700 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
