| CVE | Description | Severity | EPSS | Flags | Modified |
|---|---|---|---|---|---|
| CVE-2025-5777 | Insufficient input validation leading to memory overread when the NetScaler is configured as a Gateway (VPN virtual server, ICA Proxy, CVPN, RDP Proxy) OR AAA virtual server | HIGH7.5 | 100%p100 | KEV+RPoC | 2026-08-04 |
| CVE-2025-32433 | Erlang/OTP is a set of libraries for the Erlang programming language. Prior to versions OTP-27.3.3, OTP-26.2.5.11, and OTP-25.3.2.20, a SSH server may allow an attacker to perform unauthenticated remote code execution (RCE). By exploiting a flaw in SSH protocol message handling, a malicious actor could gain unauthorized access to affected systems and execute arbitrary commands without valid credentials. This issue is patched in versions OTP-27.3.3, OTP-26.2.5.11, and OTP-25.3.2.20. A temporary workaround involves disabling the SSH server or to prevent access via firewall rules. | CRITICAL10.0 | 99%p100 | KEVWeaponized | 2026-06-17 |
| CVE-2024-55591 | An Authentication Bypass Using an Alternate Path or Channel vulnerability [CWE-288] affecting FortiOS version 7.0.0 through 7.0.16 and FortiProxy version 7.0.0 through 7.0.19 and 7.2.0 through 7.2.12 allows a remote attacker to gain super-admin privileges via crafted requests to Node.js websocket module. | CRITICAL9.8 | 98%p100 | KEV+RPoC | 2026-08-05 |
| CVE-2026-33017 | Langflow is a tool for building and deploying AI-powered agents and workflows. In versions prior to 1.9.0, the POST /api/v1/build_public_tmp/{flow_id}/flow endpoint allows building public flows without requiring authentication. When the optional data parameter is supplied, the endpoint uses attacker-controlled flow data (containing arbitrary Python code in node definitions) instead of the stored flow data from the database. This code is passed to exec() with zero sandboxing, resulting in unauthenticated remote code execution. This is distinct from CVE-2025-3248, which fixed /api/v1/validate/code by adding authentication. The build_public_tmp endpoint is designed to be unauthenticated (for public flows) but incorrectly accepts attacker-supplied flow data containing arbitrary executable code. This issue has been fixed in version 1.9.0. | CRITICAL9.8 | 96%p100 | KEVWeaponized | 2026-06-17 |
| CVE-2024-57727 | SimpleHelp remote support software v5.5.7 and before is vulnerable to multiple path traversal vulnerabilities that enable unauthenticated remote attackers to download arbitrary files from the SimpleHelp host via crafted HTTP requests. These files include server configuration files containing various secrets and hashed user passwords. | HIGH7.5 | 95%p100 | KEV+RFunctional | 2026-08-04 |
| CVE-2026-20230 | A vulnerability in Cisco Unified Communications Manager (Unified CM) and Cisco Unified Communications Manager Session Management Edition (Unified CM SME) could allow an unauthenticated, remote attacker to conduct server-side request forgery (SSRF) attacks through an affected device. This vulnerability is due to improper input validation for specific HTTP requests. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to write files to the underlying operating system that could be used later to elevate to root. Note: Cisco has assigned this security advisory a Security Impact Rating (SIR) of Critical rather than High as the score indicates. The reason is that exploitation of this vulnerability could result in an attacker elevating privileges to root. Note: To exploit this vulnerability, the WebDialer service must be enabled. WebDialer is disabled by default. | HIGH8.6 | 88%p100 | KEVPoC | 2026-07-22 |
| CVE-2025-33073 | Improper access control in Windows SMB allows an authorized attacker to elevate privileges over a network. | HIGH8.8 | 80%p100 | KEVPoC | 2026-06-17 |
| CVE-2025-66376 | Zimbra Collaboration (ZCS) 10 before 10.0.18 and 10.1 before 10.1.13 allows Classic UI stored XSS via Cascading Style Sheets (CSS) @import directives in an HTML e-mail message. | MEDIUM6.1 | 19%p97 | KEV | 2026-06-17 |
| CVE-2026-55255 | Langflow is a tool for building and deploying AI-powered agents and workflows. Prior to 1.9.1, an Insecure Direct Object Reference (IDOR) vulnerability in /api/v1/responses endpoint allows an authenticated attacker to execute any flow belonging to another user by specifying the victim's flow ID in the request. This vulnerability is fixed in 1.9.1. | CRITICAL9.9 | 0.89%p56 | KEVPoC | 2026-07-08 |
