A vulnerability in versions prior to 1.2.0 allows an attacker who controls content on the target site, or on a subdomain of the target site (either via XSS, or otherwise) to bypass CSRF checks and issue requests on user's behalf. Due to misuse of the Go `net/http` library, nosurf categorizes all incoming requests as plain-text HTTP requests, in which case the `Referer` header is not checked to have the same origin as the target webpage. If the attacker has control over HTML contents on either the target website (e.g. `example.com`), or on a website hosted on a subdomain of the target (e.g. `attacker.example.com`), they will also be able to manipulate cookies set for the target website. By acquiring the secret CSRF token from the cookie, or overriding the cookie with a new token known to the attacker, `attacker.example.com` is able to craft cross-site requests to `example.com`. A patch for the issue was released in nosurf 1.2.0. In lieu of upgrading to a patched version of nosurf, users may additionally use another HTTP middleware to ensure that a non-safe HTTP request is coming from the same origin (e.g. by requiring a `Sec-Fetch-Site: same-origin` header in the request)."}, {"lang": "es", "value": "nosurf es un middleware de protecci\u00f3n contra cross-site request forgery (CSRF) para Go. Una vulnerabilidad en versiones anteriores a la 1.2.0 permite a un atacante que controla el contenido del sitio web objetivo o de un subdominio del mismo (ya sea mediante XSS o de otro modo) eludir las comprobaciones CSRF y emitir solicitudes en nombre del usuario. Debido al uso indebido de la librer\u00eda `net/http` de Go, nosurf categoriza todas las solicitudes entrantes como solicitudes HTTP de texto plano, en cuyo caso no se comprueba que el encabezado `Referer` tenga el mismo origen que la p\u00e1gina web objetivo. Si el atacante controla el contenido HTML del sitio web objetivo (p. ej., `example.com`) o de un sitio web alojado en un subdominio del sitio objetivo (p. ej., `attacker.example.com`), tambi\u00e9n podr\u00e1 manipular las cookies configuradas para el sitio web objetivo. Al obtener el token CSRF secreto de la cookie o sobrescribirla con un nuevo token conocido por el atacante, `attacker.example.com` puede generar solicitudes entre sitios a `example.com`. Se public\u00f3 una correcci\u00f3n para este problema en nosurf 1.2.0. En lugar de actualizar a una versi\u00f3n parcheada de nosurf, los usuarios pueden usar otro middleware HTTP para garantizar que una solicitud HTTP no segura provenga del mismo origen (por ejemplo, al requerir un encabezado `Sec-Fetch-Site: same-origin` en la solicitud)."}], "lastModified": "2025-06-23T14:55:07.967", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:nosurf_project:nosurf:*:*:*:*:*:go:*:*", "vulnerable": true, "matchCriteriaId": "C2513CBF-78BE-420F-9448-6C4226E36EC9", "versionEndExcluding": "1.2.0"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
