v2.0.19

v2.0.19 09 Jan 2024
[New Features]
  * [jws] Added jws.IsVerificationError to check if the error returned by `jws.Verify`
    was caused by actual verification step or something else, for example, while fetching
    a key from datasource
[Security Fixes]


[jws] JWS messages formated in full JSON format (i.e. not the compact format, which
consists of three base64 strings concatenated with a '.') with missing "protected"
headers could cause a panic, thereby introducing a possiblity of a DoS.
This has been fixed so that the jws.Parse function succeeds in parsing a JWS message
lacking a protected header. Calling jws.Verify on this same JWS message will result
in a failed verification attempt. Note that this behavior will differ slightly when
parsing JWS messages in compact form, which result in an error.

v2.0.18

v2.0.18 03 Dec 2023
[Security Fixes]
  * [jwe] A large number in p2c parameter for PBKDF2 based encryptions could cause a DoS attack,
    similar to https://nvd.nist.gov/vuln/detail/CVE-2022-36083.  All users who use JWE via this
    package should upgrade. While the JOSE spec allows for encryption using JWE on JWTs, users of
    the `jwt` package are not immediately susceptible unless they explicitly try to decrypt
    JWTs -- by default the `jwt` package verifies signatures, but does not decrypt messages.
    [GHSA-7f9x-gw85-8grf]

v2.0.17

v2.0.17 20 Nov 2023
[Bug Fixes]
  * [jws] Previously, `jws.UnregisterSigner` did not remove the previous signer instance when
    the signer was registered and unregistered multiple times ([#1016](https://github.com/lestrrat-go/jwx/issues/1016)). This has been fixed.
[New Features]

[jwe] (EXPERIMENTAL) jwe.WithCEK has been added to extract the content encryption key (CEK) from the Decrypt operation.
[jwe] (EXPERIMENTAL) jwe.EncryptStatic has been added to encrypt content using a static CEK.
Using static CEKs has serious security implications, and you should not use
this unless you completely understand the risks involved.
