A vulnerability has been identified in the JSON Web Encryption (JWE) decryption interfaces, specifically related to the [support for decompressing plaintext after its decryption](https://www.rfc-editor.org/rfc/rfc7516.html#section-4.1.3). This allows an adversary to exploit specific scenarios where the compression ratio becomes exceptionally high. As a result, the length of the JWE token, which is determined by the compressed content's size, can land below application-defined limits. In such cases, other existing application level mechanisms for preventing resource exhaustion may be rendered ineffective. Note that as per [RFC 8725](https://www.rfc-editor.org/rfc/rfc8725.html#name-avoid-compression-of-encryp) compression of data SHOULD NOT be done before encryption, because such compressed data often reveals information about the plaintext. For this reason the v5.x major version of `jose` removed support for compressed payloads entirely and is therefore NOT affected by this advisory. ...
