n8n >= 0.123.0 and < 1.121.3 - Remote Code Execution

  • 漏洞ID: CVE-2026-21877
  • CVE: CVE-2026-21877 (2026)
  • 严重程度: 🔴 CRITICAL
  • 风险等级: 极高风险 (5/5)
  • 影响资产: 未知
  • 预估影响: 数千个
  • EPSS: 0.00029 (percentile 0.07706) @ 2026-01-28

描述: n8n versions >= 0.123.0 and < 1.121.3 contain a critical authenticated remote code execution vulnerability via arbitrary file write. An authenticated user can exploit the Git node to overwrite critical files and execute untrusted code on the n8n server, potentially leading to full system compromise. The vulnerability affects both self-hosted and n8n Cloud instances.

Ivanti Connect Secure - Stack-based Buffer Overflow

  • 漏洞ID: CVE-2025-22457
  • CVE: CVE-2025-22457 (2025)
  • 严重程度: 🔴 CRITICAL
  • 风险等级: 极高风险 (5/5)
  • 影响资产: 未知
  • 预估影响: 数千个
  • EPSS: 0.55523 (percentile 0.98004) @ 2026-01-28

描述: Ivanti Connect Secure before version 22.7R2.6, Ivanti Policy Secure before version 22.7R1.4, and Ivanti ZTA Gateways before version 22.8R2.2 contain a stack-based buffer overflow caused by improper input handling, allowing remote attackers to execute arbitrary code without authentication.

GitLab - SAML Authentication Bypass

  • 漏洞ID: CVE-2025-25291
  • CVE: CVE-2025-25291 (2025)
  • 严重程度: 🔴 CRITICAL
  • 风险等级: 极高风险 (5/5)
  • 影响资产: GitLab 平台
  • 预估影响: 数千个
  • EPSS: 0.13848 (percentile 0.9411) @ 2026-01-28

描述: ruby-saml provides security assertion markup language (SAML) single sign-on (SSO) for Ruby. An authentication bypass vulnerability was found in ruby-saml prior to versions 1.12.4 and 1.18.0 due to a parser differential. ReXML and Nokogiri parse XML differently; the parsers can generate entirely different document structures from the same XML input. That allows an attacker to be able to execute a Signature Wrapping attack. This issue may lead to authentication bypass. Versions 1.12.4 and 1.18.0 fix the issue.

Erlang/OTP SSH - Remote Code Execution

  • 漏洞ID: CVE-2025-32433
  • CVE: CVE-2025-32433 (2025)
  • 严重程度: 🔴 CRITICAL
  • 风险等级: 极高风险 (5/5)
  • 影响资产: 未知
  • 预估影响: 数千个
  • EPSS: 0.44334 (percentile 0.97448) @ 2026-01-28

描述: 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.

Allegra - Authentication Bypass via Predictable Password Reset Token

  • 漏洞ID: CVE-2025-6216
  • CVE: CVE-2025-6216 (2025)
  • 严重程度: 🔴 CRITICAL
  • 风险等级: 极高风险 (5/5)
  • 影响资产: 未知
  • 预估影响: 数千个
  • EPSS: 0.31434 (percentile 0.96647) @ 2026-01-28

描述: Allegra calculateTokenExpDate Password Recovery Authentication Bypass Vulnerability. This vulnerability allows remote attackers to bypass authentication on affected installations of Allegra. Authentication is not required to exploit this vulnerability. The specific flaw exists within the password recovery mechanism. The issue results from reliance upon a predictable value when generating a password reset token. An attacker can leverage this vulnerability to bypass authentication on the application.

RustFS < 1.0.0-alpha.77 - Hardcoded gRPC Authentication Token

  • 漏洞ID: CVE-2025-68926
  • CVE: CVE-2025-68926 (2025)
  • 严重程度: 🔴 CRITICAL
  • 风险等级: 极高风险 (5/5)
  • 影响资产: 未知
  • 预估影响: 数千个
  • EPSS: 0.06663 (percentile 0.90982) @ 2026-01-28

描述: RustFS before 1.0.0-alpha.77 used a hardcoded gRPC authentication token "rustfs rpc" that could not be changed without recompiling and this allowed unauthenticated remote attackers to gain full administrative access to the gRPC API.

  • 影响资产: 未知
  • 预估影响: 数千个
  • EPSS: 0.00029 (percentile 0.07706) @ 2026-01-28

Backdrop CMS - Cross-Site Scripting

  • 漏洞ID: CVE-2025-25062
  • CVE: CVE-2025-25062 (2025)
  • 严重程度: 🟡 MEDIUM
  • 风险等级: 高风险 (4/5)
  • 影响资产: 未知
  • 预估影响: 数千个
  • EPSS: 0.42843 (percentile 0.97376) @ 2026-01-28

描述: An XSS issue was discovered in Backdrop CMS 1.28.x before 1.28.5 and 1.29.x before 1.29.3. It doesn't sufficiently isolate long text content when the CKEditor 5 rich text editor is used. This allows a potential attacker to craft specialized HTML and JavaScript that may be executed when an administrator attempts to edit a piece of content. This vulnerability is mitigated by the fact that an attacker must have the ability to create long text content (such as through the node or comment forms) and an administrator must edit (not view) the content that contains the malicious content. This problem only exists when using the CKEditor 5 module.
