Summary
### 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 would appear to be valid but would not have been genuinely issued by the IDP. ### Patches Version 0.4.2 bumps the dependency which should fix the issue. ### For more information Please see [the advisory in goxmldsig](https://github.com/russellhaering/goxmldsig/security/advisories/GHSA-q547-gmf8-8jr7) ## Credits The original vulnerability was discovered by @jupenur. Thanks to @russellhaering for the heads up.
