CVE-2026-89318

JweRsaKeyEncryptionDecryptorImpl.Decrypt panics on attacker-chosen IV length (stdlib GCM.Open reached without nonce-size check) PUBLISHED

Description (CNA)

`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.

Affected (CNA)

Vendor / productVersions
Eclipse Foundation / Eclipse KeyPont - GOSEaffected 0.8.0 through 0.13.0-rc1
Eclipse Foundation / Eclipse KeyPont - GOSEaffected 0 before 1.0.0-rc4
