"value": "In Secure Headers (RubyGem secure_headers), a directive injection vulnerability is present in versions before 3.8.0, 5.1.0, and 6.2.0. If user-supplied input was passed into append/override_content_security_policy_directives, a semicolon could be injected leading to directive injection. This could be used to e.g. override a script-src directive. Duplicate directives are ignored and the first one wins. The directives in secure_headers are sorted alphabetically so they pretty much all come before script-src. A previously undefined directive would receive a value even if SecureHeaders::OPT_OUT was supplied. The fixed versions will silently convert the semicolons to spaces and emit a deprecation warning when this happens. This will result in innocuous browser console messages if being exploited/accidentally used. In future releases, we will raise application errors resulting in 500s. Depending on what major version you are using, the fixed versions are 6.2.0, 5.1.0, 3.8.0."

"value": "En Secure Headers (secure_headers de RubyGem), una vulnerabilidad de inyecci\u00f3n de directiva est\u00e1 presente en las versiones anteriores a 3.8.0, 5.1.0 y 6.2.0. Si una entrada suministrada por el usuario fue pasada a append/override_content_security_policy_directives, se podr\u00eda inyectar un punto y coma conllevando a una inyecci\u00f3n de directiva. Esto podr\u00eda ser usado para, por ejemplo anular una directiva script-src. Las directivas duplicadas son ignoradas y la primera gana. Las directivas en secure_headers est\u00e1n ordenadas alfab\u00e9ticamente, por lo que casi todas van antes de script-src. Una directiva previamente indefinida recibir\u00eda un valor inclusive si la funci\u00f3n SecureHeaders::OPT_OUT fue suministrada. Las versiones corregidas convertir\u00e1n silenciosamente los puntos y comas en espacios y emitir\u00e1n una advertencia de desaprobaci\u00f3n cuando esto suceda. Esto resultar\u00e1 en mensajes inocuos de la consola del navegador si est\u00e1 siendo explotada o usada accidentalmente. En futuras versiones, generaremos errores de aplicaci\u00f3n resultando en 500. Seg\u00fan la versi\u00f3n principal que est\u00e9 usando, las versiones corregidas son 6.2.0, 5.1.0, 3.8.0."
