| CVE-2025-66568 | The ruby-saml library implements the client side of an SAML authorization. Versions up to and including 1.12.4, are vulnerable to authentication bypass through the libxml2 canonicalization process used by Nokogiri for document transformation, which allows an attacker to execute a Signature Wrapping attack. When libxml2’s canonicalization is invoked on an invalid XML input, it may return an empty string rather than a canonicalized node. ruby-saml then proceeds to compute the DigestValue over this | [email protected] | 9.3 | 0.04% | 2025-12-09 | 2025-12-10 |
| CVE-2025-66567 | The ruby-saml library is for implementing the client side of a SAML authorization. ruby-saml versions up to and including 1.12.4 contain an authentication bypass vulnerability due to an incomplete fix for CVE-2025-25292. ReXML and Nokogiri parse XML differently, generating entirely different document structures from the same input. This allows an attacker to execute a Signature Wrapping attack. This issue is fixed in version 1.18.0. | [email protected] | 9.3 | 0.05% | 2025-12-09 | 2025-12-10 |
| CVE-2025-25293 | ruby-saml provides security assertion markup language (SAML) single sign-on (SSO) for Ruby. Prior to versions 1.12.4 and 1.18.0, ruby-saml is susceptible to remote Denial of Service (DoS) with compressed SAML responses. ruby-saml uses zlib to decompress SAML responses in case they're compressed. It is possible to bypass the message size check with a compressed assertion since the message size is checked before inflation and not after. This issue may lead to remote Denial of Service (DoS).

| CVE-2025-25292 | ruby-saml provides security assertion markup language (SAML) single sign-on (SSO) for Ruby. An authentication bypass vulnerability was found in ruby-saml prior to versions 1.12.4 and 1.18.0 due to a parser differential. ReXML and Nokogiri parse XML differently, the parsers can generate entirely different document structures from the same XML input. That allows an attacker to be able to execute a Signature Wrapping attack. This issue may lead to authentication bypass. Versions 1.12.4 and 1.18.0 c | [email protected] | 9.3 | 3.32% | 2025-03-12 | 2025-11-03 |

ReXML and Nokogiri parse XML differently; the parsers can generate entirely different document structures from the same XML input.

| CVE-2024-45409 | 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. | [email protected] | 10.0 | 44.64% | 2024-09-10 | 2024-11-21 |
| CVE-2015-20108 | xml_security.rb in the ruby-saml gem before 1.0.0 for Ruby allows XPath injection and code execution because prepared statements are not used. | [email protected] | 9.8 | 0.40% | 2023-05-27 | 2025-01-14 |
| CVE-2017-11428 | OneLogin Ruby-SAML 1.6.0 and earlier may incorrectly utilize the results of XML DOM traversal and canonicalization APIs in such a way that an attacker may be able to manipulate the SAML data without invalidating the cryptographic signature, allowing the attack to potentially bypass authentication to SAML service providers. | [email protected] | 7.7 | 0.37% | 2019-04-17 | 2024-11-21 |
| CVE-2016-5697 | Ruby-saml before 1.3.0 allows attackers to perform XML signature wrapping attacks via unspecified vectors. | [email protected] | 7.5 | 0.42% | 2017-01-23 | 2026-05-13 |
