CVE-2025-25291 3 Netapp, Omniauth, Onelogin 3 Storagegrid, Omniauth Saml, Ruby-saml 2025-08-01 N/A 9.8 CRITICAL
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 fix the issue.
CVE-2025-25292 3 Netapp, Omniauth, Onelogin 3 Storagegrid, Omniauth Saml, Ruby-saml 2025-08-01 N/A 9.8 CRITICAL

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 contain a patch for the issue.
CVE-2025-25293 2 Omniauth, Onelogin 2 Omniauth Saml, Ruby-saml 2025-08-01 N/A 7.5 HIGH
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). Versions 1.12.4 and 1.18.0 fix the issue.
CVE-2024-45409 3 Gitlab, Omniauth, Onelogin 3 Gitlab, Omniauth Saml, Ruby-saml 2024-11-21 N/A 10.0 CRITICAL
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.
CVE-2020-36599 1 Omniauth 1 Omniauth 2024-11-21 N/A 9.8 CRITICAL
lib/omniauth/failure_endpoint.rb in OmniAuth before 1.9.2 (and before 2.0) does not escape the message_key value.
CVE-2017-18076 2 Debian, Omniauth 2 Debian Linux, Omniauth 2024-11-21 5.0 MEDIUM 7.5 HIGH
In strategy.rb in OmniAuth before 1.3.2, the authenticity_token value is improperly protected because POST (in addition to GET) parameters are stored in the session and become available in the environment of the callback phase.
CVE-2017-11430 1 Omniauth 1 Omniauth Saml 2024-11-21 7.5 HIGH 7.7 HIGH
OmniAuth OmnitAuth-SAML 1.9.0 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.
CVE-2015-9284 1 Omniauth 1 Omniauth 2024-11-21 6.8 MEDIUM 8.8 HIGH
The request phase of the OmniAuth Ruby gem (1.9.1 and earlier) is vulnerable to Cross-Site Request Forgery when used as part of the Ruby on Rails framework, allowing accounts to be connected without user intent, user interaction, or feedback to the user. This permits a secondary account to be able to sign into the web application as the primary account.
