Improper Cryptographic Verification

Bouncy Castle for Java is vulnerable to Improper Cryptographic Verification. The vulnerability is due to the content not being properly bound to the MAC, which allows an attacker to modify the authenticated content without the integrity check detecting the tampering...

CVE-2026-85995: Improper Verification of Cryptographic Signature

Notepad++ is a free and open-source source code editor. From 8.9.7 until 8.9.8, the Notepad++ updater and signature verification path can accept a modified GUP.exe file whose embedded certificate metadata remains present even though its Authenticode digest is invalid. An attacker who can replace ...

CVE-2026-94368: Improper Verification of Cryptographic Signature

A flaw was found in the signature verification logic of noobaa-core, the core component of the NooBaa Multicloud Object Gateway. The issue occurs when the service processes S3 presigned URLs using Signature Version 4 SigV4. Due to improper validation, the service fails to reject requests containi...

CVE-2026-87802 Apache Syncope: SRA OAuth2 JWT signature verification bypass

Improper verification of cryptographic signature vulnerability in Apache Syncope. When SRA is configured for OAuth 2.0 without JWKS set URI assigned, an attacker can forge arbitrary JWTs to impersonate any user identity and permissions, gaining full access to services proxied by SRA. This issue...

CVE-2026-54155: Improper Verification of Cryptographic Signature

node-opcua is an OPC UA implementation for TypeScript and Node.js. Prior to 2.166.0, the UserNameIdentityToken authentication handler in packages/node-opcua-server/source/opcuaserver.ts decrypts an RSA-OAEP password blob but does not verify that the trailing bytes match the current session...

CVE-2026-79389: Improper Verification of Cryptographic Signature

Trueview T18161 S 6.0.23.4 contains an improper verification in MQTT command processing. An attacker with network access can replay or modify captured MQTT messages, including security-related nonce, timestamp, and signature fields, and the device accepts the modified messages and executes the...

Improper Cryptographic Verification

Bouncy Castle is vulnerable to Improper Cryptographic Verification. The vulnerability is due to the KCCMBlockCipher MAC not binding the nonce when no Additional Authenticated Data AAD is present, which allows an attacker to forge authenticated ciphertexts across different nonces...

dotnet: .NET Security Feature Bypass Vulnerability

A flaw was found in .NET. An unauthorized attacker can exploit this vulnerability over a network due to improper verification of cryptographic signatures. This allows the attacker to bypass a critical security feature, potentially leading to significant compromise of confidentiality, integrity, a...

Improper Verification Of Cryptographic Signature

Spring Security is vulnerable to Improper Verification of Cryptographic Signature. The vulnerability is due to SAML Responses and LogoutRequest/LogoutResponse elements being decrypted without requiring a valid signature, which allows an attacker to craft malicious SAML payloads and use the Servic...
