Signature Validation Bypass
### Impact An authentication bypass exists in the [goxmldsig](https://github.com/russellhaering/goxmldsig/security/advisories/GHSA-q547-gmf8-8jr7) this library uses to determine if SAML assertions are genuine. An attacker could craft a SAML response that woul…

Missing validation of JWT signature in `ManyDesigns/Portofino`
Portofino is an open source web development framework. Portofino before version 5.2.1 did not properly verify the signature of JSON Web Tokens. This allows forging a valid JWT. The issue will be patched in the upcoming 5.2.1 release.

Openssl: openssl: signature forgery via improper pkcs-1 padding removal leading to certificate validation bypass
A flaw was found in OpenSSL. When configured to use an RSA key with exponent 3, OpenSSL improperly removes PKCS-1 padding before generating a hash. This allows remote attackers to forge PKCS #1 v1.5 signatures. Consequently, OpenSSL may incorrectly verify X.5…
