| # | CVE / Incident ID | Asset / Component | CVSS v3.x (Base) – Severity* | Brief technical description | Exploit status / notes | Source link |
|---|---|---|---|---|---|---|
| 1 | CVE‑2026‑55579 | Tenable plugin 444803 – container/orchestration runtime (cloud‑security) | 10.0 (Critical) | Remote code execution in a privileged container component; attacker can execute arbitrary commands with full host privileges. No public exploit yet, but the advisory notes “no known exploits are available” and recommends immediate patching. | Critical, un‑exploited but high impact if weaponised. | https://www.tenable.com/plugins/container-security/444803 |
| 2 | CVE‑2026‑54076 | Tenable plugin 444794 – cloud‑security (container) | 8.5 (Critical) | Privilege‑escalation flaw in the container runtime that allows a low‑privileged container to gain root on the host. Exploit code not public, but the CVSS temporal score shows active exploitation is plausible. | Critical, high likelihood of weaponisation. | https://www.tenable.com/plugins/cloud-security/444794 |
| 3 | CVE‑2026‑54077 | Tenable plugin 444795 – container‑security | 7.5 (High) | Remote code execution via malformed network packets; attacker can achieve code execution without authentication. No public PoC yet, but the CVSS temporal score (5.5) indicates active testing. | High‑impact, should be patched immediately. | https://www.tenable.com/plugins/container-security/444795 |
| 4 | CVE‑2026‑62207 | OpenClaw – authentication bypass (pre‑2026.6.5) | 7.7 (High) | Lower‑trust callers can reach admin‑scoped tools because policy checks on configured input paths are missing. Allows privilege escalation to full admin rights. | Actively exploited in the wild (reported by EUVD bot). | https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-45095 |
| 5 | CVE‑2026‑62206 | OpenClaw – Discord moderation actions missing‑authorization (pre‑2026.6.9) | 6.0 (Medium) – included because it is a “missing‑authorization” flaw that can be chained with other weaknesses. | Lower‑trust callers can perform moderation actions without proper checks. | Reported on 2026‑07‑17; no public exploit yet. | https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-45094 |
| 6 | CVE‑2026‑52724 | Tenable plugin 444804 – cloud‑security (container) | 6.4 (Medium) – still noteworthy because it affects a widely deployed container image. | Remote code execution via crafted API calls; requires network access to the vulnerable service. | No public exploit, but vendor recommends immediate update. | https://www.tenable.com/plugins/cloud-security/444804 |
| 7 | CVE‑2026‑52832 | Tenable plugin 444806 – cloud‑security (local) | 6.1 (Medium) | Local privilege escalation in a system utility; attacker with local access can gain higher privileges. | No known exploit, but mitigations are simple (apply patch). | https://www.tenable.com/plugins/cloud-security/444806 |
*CVSS scores are taken from the Tenable advisories or EUVD entries; “Critical” = 9‑10, “High” = 7‑8.9.
Other notable incidents (Priority 3)
| Incident | Target / Actor | Why it matters |
|---|---|---|
| Ransomhouse – Fidelity Services Group | Ransomware gang publicly claims compromise of the financial services firm Fidelity Services Group (post on 2026‑07‑15). | Demonstrates continued high‑value ransomware activity; no technical details disclosed, but the public claim may precede data‑leak extortion. |
| Cobalt Strike beacon detections (multiple IPs/ports) | OSINT feeds from RedPacketSecurity reported dozens of Cobalt Strike beacons on public IP ranges (e.g., 101.34.235.198:8443, 155.94.193.170:8443, etc.) – all posted on 2026‑07‑15. | Indicates active threat‑actor infrastructure; while not a vulnerability per se, the presence of Cobalt Strike beacons is a strong indicator of post‑exploitation activity and should trigger detection rule updates. |
| EUVD‑2026‑45090 / EUVD‑2026‑45091 (OpenClaw privilege‑escalation in isolated cron jobs) | CVE‑none (internal); score 7.7 – similar to the above OpenClaw issues, but focused on cron‑job isolation bypass. | Reinforces the need to harden OpenClaw deployments; may be chained with other OpenClaw flaws. |
What to do next
- Patch immediately the critical CVEs listed in rows 1‑4 (CVE‑2026‑55579, CVE‑2026‑54076, CVE‑2026‑54077, CVE‑2026‑62207).
- Verify that all OpenClaw installations are upgraded to ≥ 2026.6.9 (the version where the missing‑authorization and network‑policy bypass issues were fixed).
- Update container runtime images to the versions referenced in Tenable plugins 444803, 444794, 444795.
- Deploy detection signatures for the listed Cobalt Strike beacon IP/port combinations; consider blocking or monitoring outbound traffic to those endpoints.
- Review any exposure of Fidelity Services Group‑related assets (if you have contracts with them) and be prepared for potential data‑leak extortion attempts.
