Filter vulnerabilities by CVSS severity, active CISA KEV exploitation, and technology stack.
WSO2 JWT Authentication Bypass and Account Takeover (CVE-2026-5430)
[Affected Scope] WSO2 Identity Server, API Manager, and products utilizing WSO2 JWT authentication modules.
[Impact] Attackers can bypass authentication using crafted JWTs, leading to full administrative account takeover.
[Mitigation] Apply official vendor patches immediately and enforce strict JWT algorithm validation policies.
SimpleHelp Authentication Bypass via Missing OIDC Signature Verification (CVE-2026-48558)
[Affected Scope] SimpleHelp versions 5.5.15 and prior, and 6.0 pre-release versions with OIDC authentication configured
[Impact] Unauthenticated remote attackers can forge identity tokens to bypass authentication, gain full technician sessions, and potentially bypass multi-factor authentication (MFA)
[Mitigation] Immediately upgrade SimpleHelp to the patched version or disable OIDC authentication until the patch is applied
Fortinet FortiOS, FortiProxy, and FortiSwitchManager Authentication Bypass via Improper Verification of SAML Cryptographic Signature (CVE-2025-59718)
[Affected Scope] FortiOS 7.0.0-7.0.17 / 7.2.0-7.2.11 / 7.4.0-7.4.8 / 7.6.0-7.6.3, FortiProxy 7.0.0-7.0.21 / 7.2.0-7.2.14 / 7.4.0-7.4.10 / 7.6.0-7.6.3, FortiSwitchManager 7.0.0-7.0.5 / 7.2.0-7.2.6.
[Impact] An unauthenticated remote attacker can bypass FortiCloud SSO authentication via a crafted SAML response message, gaining full administrative access to the affected device.
[Mitigation] Immediately upgrade to the patched firmware versions, or disable FortiCloud SSO login and restrict administrative access to trusted IP addresses as a temporary workaround.
IGEL OS Secure Boot Bypass and Arbitrary SquashFS Mount Vulnerability (CVE-2025-47827)
[Affected Scope] IGEL OS systems prior to version 11
[Impact] Attackers can bypass cryptographic signature verification to mount a crafted root filesystem from an unverified SquashFS image, leading to complete system compromise
[Mitigation] Immediately upgrade IGEL OS to version 11 or later and restrict physical access to boot interfaces
Windows Authenticode Digital Signature Bypass and Spoofing Vulnerability (CVE-2020-1464) Analysis & Mitigation Guide
[Affected Scope] All major supported Windows operating systems, including Windows 7, 8.1, 10, and Windows Server 2008, 2012, 2016, 2019, 2020
[Impact] Attackers can bypass security controls (such as EDRs, antivirus, and AppLocker) by appending malicious payloads to legitimately signed files, making them appear valid
[Mitigation] Apply the official Microsoft cumulative security updates (KB) immediately and audit systems for anomalous signed files
Palo Alto Networks PAN-OS SAML Signature Verification Bypass Vulnerability (CVE-2020-2021)
[Affected Scope] PAN-OS 8.1, 9.0, and 9.1 versions, Panorama, and GlobalProtect gateways with SAML authentication enabled and 'Validate Identity Provider Certificate' disabled
[Impact] Unauthenticated remote attackers can bypass SAML signature verification to gain administrative access to PAN-OS/Panorama web interfaces or access protected network resources
[Mitigation] Upgrade PAN-OS to patched versions (9.1.3, 9.0.9, 8.1.15 or later) or enable the 'Validate Identity Provider Certificate' option in the SAML Identity Provider Server Profile
Microsoft Windows WinVerifyTrust Authenticode Signature Bypass and Remote Code Execution Vulnerability (CVE-2013-3900)
[Affected Scope] All currently supported versions of Microsoft Windows, including Windows 10, Windows 11, and Windows Server
[Impact] Attackers can inject malicious code into the unverified padding areas of signed PE files without invalidating the digital signature, bypassing security controls to execute arbitrary code
[Mitigation] Enable the 'EnableCertPaddingCheck' registry setting to enforce strict Authenticode signature verification across all endpoints
