  • CVE: CVE-2026-55450 (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: 0.06402 (percentile 0.92974) @ 2026-07-31

Keras Model.load_model - Arbitrary Code Execution

  • 漏洞ID: CVE-2025-1550
  • CVE: CVE-2025-1550 (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: 0.02803 (percentile 0.85053) @ 2026-07-31

描述: The Keras Model.load_model function permits arbitrary code execution, even with safe_mode=True, through a manually constructed, malicious .keras archive. By altering the config.json file within the archive, an attacker can specify arbitrary Python modules and functions, along with their arguments, to be loaded and executed during model loading

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: 0.19506 (percentile 0.97099) @ 2026-07-31

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.
