Hi,

The following vulnerability was published for ruby-saml.

CVE-2024-45409[0]:
| The Ruby SAML library is for implementing the client side of a SAML
| authorization. Ruby-SAML in <= 12.2 and 1.13.0 <= 1.16.0 does not
| properly verify the signature of the SAML Response. An
| unauthenticated attacker with access to any signed saml document (by
| the IdP) can thus forge a SAML Response/Assertion with arbitrary
| contents. This would allow the attacker to log in as arbitrary user
| within the vulnerable system. This vulnerability is fixed in 1.17.0
| and 1.12.3.


If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
