CVE-2026-89318 Details
Description
`JweRsaKeyEncryptionDecryptorImpl.Decrypt` passed the JWE's initialization vector to `cipher.AEAD.Open` without checking its length. The Go standard library **panics** rather than returning an error when a GCM nonce is not exactly `NonceSize()` bytes, so a JWE carrying a wrong-sized IV crashes the decrypting goroutine.
A denial-of-service vulnerability has been identified in the Eclipse KeyPont JWE RSA key encryption decryptor. The issue arises because the decryption method does not validate the length of the initialization vector (IV) before passing it to the cryptographic function. In Go, the standard library panics when a GCM nonce is not the correct length, causing the decryption process to crash. This vulnerability affects versions of the 'github.com/eclipse-keypont/gose' package prior to 'v1.0.0-rc4' and 'github.com/ThalesGroup/gose' versions '0.8.0' through '0.13.0-rc1'.
Users can upgrade to 'github.com/eclipse-keypont/gose' version 'v1.0.0-rc4' or later. For those using 'github.com/ThalesGroup/gose', it is necessary to change the module path to 'github.com/eclipse-keypont/gose' and update the version to 'v1.0.0-rc4', as the 'ThalesGroup' version '0.13.0-rc1' is still vulnerable.
