passport-saml-encrypted through 0.1.13 contains an XML signature wrapping vulnerability where signature verification and assertion extraction use independent XPath lookups with no cross-validation. Attackers holding any validly signed SAML message can prepend a forged unsigned assertion that gets accepted as the verified identity while the genuine signature validates against the original assertion…

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 consumer service endpoint to receive authenticated profiles without valid signatures.

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 exception during ECDH key derivation, crashing the server.

YesWiki is a wiki system written in PHP. From version 4.6.2 to before version 4.6.6, HttpSignatureService::verifySignature() checks the result of PHP's openssl_verify() with a loose boolean negation - if (!openssl_verify(...)) { throw ... }. PHP's openssl_verify has four possible return values: 1, 0, -1, and "false". The -1 row is the bypass: PHP's truthiness rules make -1 a truthy value, so !(-1)…

Improper OCSP response validation in the Snowflake Python, Go, JDBC, and Node.js drivers allowed a revoked TLS certificate to be accepted as valid, because OCSP responses were not reliably bound to the certificate being validated and definitive verification failures were treated as transient.

node-forge through 1.4.0 fails to validate element count in nested DigestAlgorithm sequences during RSA PKCS#1 v1.5 signature verification. Attackers can embed garbage bytes inside the DigestAlgorithm sequence to forge valid signatures for arbitrary messages using low-exponent RSA keys. This is an incomplete fix for CVE-2026-33894.

Vulnerabilidad alta en controlador Phison PS3111-S11 permite falsificación de firmware

El controlador de almacenamiento Phison PS3111-S11 valida firmas RSA utilizando claves públicas embebidas en la imagen del firmware en lugar de almacenamiento inmutable, permitiendo a atacantes generar pares de claves RSA arbitrarios y firmar firmware modificado que el controlador acepta como legítimo. Esta vulnerabilidad afecta directamente a servidores, sistemas de backup y centros de datos en LATAM que utilizan almacenamiento basado en estos controladores, comprometiendo la integridad del firmware de dispositivos de almacenamiento altas.

The Omnivore API (packages/api) before the fix in commit abf53d6 contains an authentication bypass in Apple sign-in token verification. The decodeAppleToken function extracted the 'alg' field from the attacker-supplied JWT header and passed it as the sole allowed algorithm to jwt.verify(). Using jsonwebtoken v8 (which does not validate key/algorithm compatibility), an attacker can set alg=HS256 an…
