hickory-resolver versions before 0.26.2 fail to propagate bogus DNSSEC proof states through the Resolver::lookup and Resolver::lookupip APIs, allowing invalid records to be returned as successful results. Attackers controlling the answering zone or positioned on the network path can have forged D...

CVE-2026-59163: Improper Verification of Cryptographic Signature

Mnemosyne is a memory layer for artificial intelligence agents. Prior to v3.10.1, the auth check in mnemosyne/core/syncserver.py parsed the JWT's header and payload using base64 decoding, then passed the token to a jwt library call with options that effectively disabled signature verification. Th...

CVE-2026-92718: Improper Verification of Cryptographic Signature

Nuclei versions before 3.11.1 cache template signature verification based only on file modification time without content checksums. Attackers can replace verified templates with unsigned malicious content and restore the original modification time to bypass signature checks and execute arbitrary...

Payload Plugins is a collection of plugins designed to enhance Payload CMS. From 0.3.0 until 0.4.0, @jhb.software/payload-cloudinary-plugin deployments with clientUploads enabled expose POST /api/cloudinary-generate-signature, whose handler in cloudinary/src/getGenerateSignature.ts passes...

CVE-2026-87802: Improper Verification of Cryptographic Signature

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-2026-89086: Improper Verification of Cryptographic Signature

In the jose package before 0.11.0 for OCaml, library calls to validate an RSA signature only confirm that PKCS 1 decoding succeeds, and proceed to declare the signature valid without the required steps that involve the public key...

CVE-2026-89042: Improper Verification of Cryptographic Signature

passport-saml-encrypted through 0.1.13 makes SAML signature verification conditional on an optional cert option, allowing attackers to bypass authentication by submitting unsigned SAML responses. Attackers can post forged SAML responses with arbitrary NameID and attributes to the assertion consum...

CVE-2023-54355: Improper Verification of Cryptographic Signature

PocketMine-MP versions before 5.3.1 and 4.23.1 fail to validate that the identityPublicKey in LoginPacket uses the required secp384r1 elliptic curve. Attackers can provide LoginPackets with keys using different curves or non-EC key types to pass login verification but trigger an uncaught exceptio...

CVE-2026-79970: Improper Verification of Cryptographic Signature

Dell SCG 5.0 Appliance versions prior to 5.36.00.16 and Dell SCG 5.0 Application versions prior to 5.36.00.00, contains an Improper Verification of Cryptographic Signature vulnerability. An unauthenticated attacker with remote access could potentially exploit this vulnerability, leading to...
