    {

      "value": "A weak robustness vulnerability exists in the AWS Encryption SDKs for Java, Python, C and Javalcript prior to versions 2.0.0. Due to the non-committing property of AES-GCM (and other AEAD ciphers such as AES-GCM-SIV or (X)ChaCha20Poly1305) used by the SDKs to encrypt messages, an attacker can craft a unique cyphertext which will decrypt to multiple different results, and becomes especially relevant in a multi-recipient setting. We recommend users update their SDK to 2.0.0 or later."

      "lang": "es",
      "value": "Se presenta una vulnerabilidad de robustez d\u00e9bil en los AWS Encryption SDKs para Java, Python, C y JavaScript versiones anteriores a 2.0.0. Debido a la propiedad non-committing de AES-GCM (y otros cifrados AEAD como AES-GCM-SIV o (X)ChaCha20Poly1305) usados por los SDK para cifrar mensajes, un atacante puede dise\u00f1ar un texto cifrado \u00fanico que descifrar\u00e1 a m\u00faltiples resultados, y se vuelve especialmente relevante en un entorno de m\u00faltiples destinatarios. Recomendamos a usuarios actualizar su SDK versiones hasta 2.0.0 o posteriores"
