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
Velociraptor versions prior to 0.76.3 contain a vulnerability in the query() plugin which allows access to all orgs with the user's current ACL token. This allows an authenticated GUI user with access in one org, to use the query() plugin, in a notebook cell, to run VQL queries on other orgs which they may not have access to. The user's permissions in the other org are the same as the permissions they have in the org containing the notebook.
Affected Products
velociraptorrapid7Detection & mitigation playbook
Vendor / applianceDetect
Inventory every rapid7 velociraptor 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 rapid7 velociraptor security patch or hotfix for CVE-2026-6290 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-2026-6290 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-2026-6290. 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-2026-6290 being exploited in your environment?
O3's eBPF runtime sensors and L7 egress monitoring detect and block the CVE-2026-6290 exploit chain at execution — protecting unpatched and end-of-life systems until the vendor patch is applied.
