| Score | CVE | Affected | EPSS | Added to KEV |
|---|---|---|---|---|
| 9.3 critical | CVE-2026-50751 KEV | checkpoint Quantum Security Gateway A logic flow weakness in Remote Access and Mobile Access certificate validation in deprecated IKEv1 key exchange allows an unauthenticated remote attacker to bypass user authentication and establish a remote access VPN connection without a valid user password. | 6.4% | 8 Jun 2026 |
| 8.7 high | CVE-2026-42271 KEV | BerriAI litellm LiteLLM is a proxy server (AI Gateway) to call LLM APIs in OpenAI (or native) format. From version 1.74.2 to before version 1.83.7, two endpoints used to preview an MCP server before saving it — POST /mcp-rest/test/connection and POST /mcp-rest/test/tools/list — accepted a full server configuration in the request body, including the command, args, and env fields used by the stdio transport. When called with a stdio configuration, the endpoints attempted to connect, which spawned the supplied command as a subprocess on the proxy host with the privileges of the proxy process. The endpoints were gated only by a valid proxy API key, with no role check. Any authenticated user — including holders of low-privilege internal-user keys — could therefore run arbitrary commands on the host. This issue has been patched in version 1.83.7. | 93% | 8 Jun 2026 |

CVSS 3.1 Base Score 7.5 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N). | 74% | 1 Jun 2026 |
| 7.8 high | CVE-2026-0257 KEV | Palo Alto Networks Cloud NGFW Authentication bypass vulnerabilities in the GlobalProtect portal and gateway of Palo Alto Networks PAN-OS® software allows the attacker to bypass security restrictions and establish an unauthorized VPN connection. Panorama and Cloud NGFW are not impacted by these issues. | 96% | 29 May 2026 |
| 9.3 critical | CVE-2026-48027 KEV | nrwl nx-console Nx Console is the user interface for Nx & Lerna. On 19 May 2026, a malicious version of Nx Console, 18.95.0, was published at 12:30 PM UTC and removed soon after at 12:48 PM UTC, leaving it available for ~18 minutes in Visual Studio Marketplace. For OpenVSX, the problem was detected later, and the compromised version was available from 12:33 UTC to 13:09 UTC (~36 minutes). Version 18.100.0 of Nx Console is not compromised and users may remediate by upgrading to that version. | 1.3% | 27 May 2026 |
| 9.3 critical | CVE-2026-8398 KEV | AVB Disc Soft DAEMON Tools Lite A supply chain attack compromised the official installation packages of DAEMON Tools Lite (Windows versions 12.5.0.2421 through 12.5.0.2434), distributed from the legitimate website daemon-tools.cc between approximately April 8, 2026, and May 5, 2026. Attackers gained unauthorized access to the vendor's (AVB Disc Soft) build or distribution infrastructure and trojanized three binaries: DTHelper.exe, DiscSoftBusServiceLite.exe, and DTShellHlp.exe. These files were digitally signed with the legitimate AVB Disc Soft code-signing certificate, allowing the malicious installers to appear trustworthy and bypass signature-based detection. | 0.96% | 27 May 2026 |
| 9.6 critical | CVE-2026-45321 KEV | @tanstack arktype-adapter On 2026-05-11, between approximately 19:20 and 19:26 UTC, 84 malicious versions across 42 @tanstack/* packages were published to the npm registry. The publishes were authenticated via the legitimate GitHub Actions OIDC trusted-publisher binding for TanStack/router, but the publish workflow itself was not modified. The attacker chained three known vulnerability classes — a pull_request_target "Pwn Request" misconfiguration, GitHub Actions cache poisoning across the fork↔base trust boundary, and runtime memory extraction of the OIDC token from the Actions runner process — to publish credential-stealing malware under a trusted identity. Each affected package received exactly two malicious versions, published a few minutes apart. | 1.1% | 27 May 2026 |
| 10.0 critical | CVE-2026-48172 KEV | LiteSpeed Technologies cPanel Plugin LiteSpeed User-End cPanel Plugin before 2.4.5 allows privilege escalation (possibly to root), as exploited in the wild in May 2026. Detection is best done via a command line of grep -rE "cpanel_jsonapi_func=redisAble" /var/cpanel/logs /usr/local/cpanel/logs/ 2>/dev/null in Bash. If you get no output, you have not been hit with exploitation of the vulnerability. If there is output, we recommend you examine the IP addresses in the list, determine if they are valid IP addresses, and if not, block them. To determine damage done, examine the system logs for use by the detected IP addresses. The issue is related to mishandling of Redis enable/disable features. The recommended minimum version is 2.4.7. | 1.0% | 26 May 2026 |
| 9.8 critical | CVE-2026-9082 KEV | Drupal core Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection') vulnerability in Drupal Drupal core allows SQL Injection. This issue affects Drupal core: from 8.9.0 before 10.4.10, from 10.5.0 before 10.5.10, from 10.6.0 before 10.6.9, from 11.0.0 before 11.1.10, from 11.2.0 before 11.2.12, from 11.3.0 before 11.3.10. | 16% | 22 May 2026 |
| 6.7 medium | CVE-2026-34926 KEV | Trend Micro, Inc. TrendAI Apex One A directory traversal vulnerability in the Apex One (on-premise) server could allow a pre-authenticated local attacker to modify a key table on the server to inject malicious code to deploy to agents on affected installations. This vulnerability is only exploitable on the on-premise version of Apex One and a potential attacker must have access to the Apex One Server and already obtained administrative credentials to the server via some other method to exploit this vulnerability. | 0.54% | 21 May 2026 |
| 9.4 critical | CVE-2025-34291 KEV | Langflow Langflow versions up to and including 1.6.9 contain a chained vulnerability that enables account takeover and remote code execution. An overly permissive CORS configuration (allow_origins='*' with allow_credentials=True) combined with a refresh token cookie configured as SameSite=None allows a malicious webpage to perform cross-origin requests that include credentials and successfully call the refresh endpoint. An attacker-controlled origin can therefore obtain fresh access_token / refresh_token pairs for a victim session. Obtained tokens permit access to authenticated endpoints — including built-in code-execution functionality — allowing the attacker to execute arbitrary code and achieve full system compromise. | 93% | 21 May 2026 |
| 7.5 high | CVE-2026-45498 KEV | Microsoft Defender Antimalware Platform Microsoft Defender Denial of Service Vulnerability | 1.3% | 20 May 2026 |
