Severity ?
9.1 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:N

Summary
WP-CLI is the command-line interface for WordPress. An improper error handling in HTTPS requests management in WP-CLI version 0.12.0 and later allows remote attackers able to intercept the communication to remotely disable the certificate verification on WP-CLI side, gaining full control over the communication content, including the ability to impersonate update servers and push malicious updates towards WordPress instances controlled by the vulnerable WP-CLI agent, or push malicious updates toward WP-CLI itself. The vulnerability stems from the fact that the default behavior of `WP_CLI\Utils\http_request()` when encountering a TLS handshake error is to disable certificate validation and retry the same request. The default behavior has been changed with version 2.5.0 of WP-CLI and the `wp-cli/wp-cli` framework (via https://github.com/wp-cli/wp-cli/pull/5523) so that the `WP_CLI\Utils\http_request()` method accepts an `$insecure` option that is `false` by default and consequently that a TLS handshake failure is a hard error by default. This new default is a breaking change and ripples through to all consumers of `WP_CLI\Utils\http_request()`, including those in separate WP-CLI bundled or third-party packages. https://github.com/wp-cli/wp-cli/pull/5523 has also added an `--insecure` flag to the `cli update` command to counter this breaking change. There is no direct workaround for the default insecure behavior of `wp-cli/wp-cli` versions before 2.5.0. The workaround for dealing with the breaking change in the commands directly affected by the new secure default behavior is to add the `--insecure` flag to manually opt-in to the previous insecure behavior.

Un manejo inapropiado de errores en la administraci\u00f3n de peticiones HTTPS en la versi\u00f3n 0.12.0 y posteriores de WP-CLI, permite a atacantes remotos capaces de interceptar la comunicaci\u00f3n desactivar remotamente la comprobaci\u00f3n del certificado en el lado de WP-CLI, obteniendo un control total sobre el contenido de la comunicaci\u00f3n, incluyendo la habilidad de hacerse pasar por servidores de actualizaci\u00f3n y empujar actualizaciones maliciosas hacia instancias de WordPress controladas por el agente vulnerable de WP-CLI, o empujar actualizaciones maliciosas hacia el propio WP-CLI. La vulnerabilidad proviene del hecho de que el comportamiento por defecto de la funci\u00f3n \"WP_CLI\\Utils\\http_request()\" cuando se encuentra un error de protocolo de enlace TLS es desactivar la comprobaci\u00f3n del certificado y volver a intentar la misma petici\u00f3n. El comportamiento por defecto ha sido cambiado con la versi\u00f3n 2.5.0 de WP-CLI y el framework \"wp-cli/wp-cli\" (por medio de https://github.com/wp-cli/wp-cli/pull/5523) para que el m\u00e9todo \"WP_CLI\\Utils\\http_request()\" acepte una opci\u00f3n \"$insecure\" que es \"false\" por defecto y en consecuentemente un fallo de protocolo de enlace TLS es un error duro por defecto. Este nuevo valor por defecto es un cambio de ruptura y se extiende a todos los consumidores de la funci\u00f3n \"WP_CLI\\Utils\\http_request()\", incluyendo aquellos en paquetes separados de WP-CLI o de terceros. https://github.com/wp-cli/wp-cli/pull/5523 tambi\u00e9n ha a\u00f1adido un flag \"--insecure\" al comando \"cli update\" para contrarrestar este cambio de ruptura. No hay una soluci\u00f3n directa para el comportamiento no seguro por defecto de las versiones anteriores a 2.5.0 de \"wp-cli/wp-cli\". La soluci\u00f3n para tratar el cambio de ruptura en los comandos directamente afectados por el nuevo comportamiento seguro por defecto es a\u00f1adir el flag \"--insecure\" para optar manualmente por el comportamiento no seguro anterior"
