CVE-2026-89312— AesGcmCryptor.Open passes attacker-controlled nonce to cipher.AEAD.Open without length check, causing panic on wrong-size IV

Quick assessment

Affected
Eclipse Foundation Eclipse KeyPont - GOSE
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

方法将调用者提供的 nonce 直接传递给了 ，而未对其长度进行检查。Go 标准库在 GCM 的 nonce 长度不严格等于 字节时，会触发panic（运行时崩溃）而非返回错误。因此，携带错误尺寸 IV 的 JWE 会导致解密协程崩溃。

Vulnerability Title
AesGcmCryptor.Open passes attacker-controlled nonce to cipher.AEAD.Open without length check, causing panic on wrong-size IV
Source: CVE Program / CVE List V5
Vulnerability Description
`AesGcmCryptor.Open` passed a caller-supplied nonce straight 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.
