Security readout for executives and security teams
CVE-2013-1812 affects Ruby applications using ruby-openid before 2.2.2. A malicious or abusive OpenID provider could make the application spend excessive CPU processing oversized XRDS or XML entity expansion content, causing a denial of service. Exposure is likely limited to Ruby applications that still use ruby-openid below 2.2.2 and process OpenID provider XRDS/XML responses. Systems not using ruby-openid or OpenID discovery are not indicated as affected by the provided sources. Treat as a targeted availability risk for legacy Ruby OpenID systems. Prioritize remediation if customer login, SSO, or public authentication depends on ruby-openid before 2.2.2. Mitigation focus: Inventory Ruby applications for ruby-openid dependencies below 2.2.2.; Upgrade ruby-openid to 2.2.2 or a later vendor-supported version.; Review vendor advisories and changelog before deployment..
