CVE-2026-50510

HIGH

CVE-2026-50510 is a high-severity (CVSS 7.8) CWE-641 vulnerability in microsoft github copilot. O3 Security detects and blocks CVE-2026-50510 exploitation at runtime via eBPF exploit-chain detection and L7 egress monitoring, even on unpatched systems.

Improper restriction of names for files and other resources in Github Copilot allows an unauthorized attacker to execute code locally.

Detection & mitigation playbook

Vendor / appliance
  1. Detect

    Inventory every microsoft github copilot 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.

  2. Fix

    Apply the microsoft github copilot security patch or hotfix for CVE-2026-50510 on the affected version, following the vendor advisory for your exact build.

  3. 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.

  4. How O3 protects you

    O3 detects and blocks CVE-2026-50510 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-2026-50510. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
