CVE-2026-17578

Kong Event Gateway vulnerable components: versions 1.0.0–1.1.1 and 1.2.0 fail to enforce key rotation before reaching the NIST SP 800-38D usage limit for AES-GCM keys when AWS IAM encryption is enabled. Under sustained high message rates that trigger a reboot without rotation, nonce collisions be...

Selection of Less-Secure Algorithm During Negotiation ('Algorithm Downgrade')

Overview aws-encryption-sdk is an AWS Encryption SDK implementation for Python Affected versions of this package are vulnerable to Selection of Less-Secure Algorithm During Negotiation 'Algorithm Downgrade' via the shared key cache. An attacker can bypass key commitment policy enforcement by...

CVE-2026-6550

The vulnerability CVE-2026-6550 affects the AWS Encryption SDK for Python in its caching layer. A cryptographic downgrade in the key cache could allow an authenticated local actor to bypass key commitment policy enforcement, enabling ciphertext to be decrypted into multiple possible plaintexts. A...

CVE-2026-6550: Selection of Less-Secure Algorithm During Negotiation

Cryptographic algorithm downgrade in the caching layer of Amazon AWS Encryption SDK for Python before version 3.3.1 and before version 4.0.5 might allow an authenticated local threat actor to bypass key commitment policy enforcement via a shared key cache, resulting in ciphertext that can be...

AWS VDP: V2Plugin.Decrypt panics on empty ciphertext (Remote DoS)

A vulnerability was discovered in the "aws-encryption-provider" component where the "V2Plugin.Decrypt" function accessed the ciphertext slice without checking if it was empty, leading to a panic and crashing the entire gRPC server process...

AWS VDP: V1Plugin.Decrypt panics on empty ciphertext (Remote DoS)

A vulnerability was discovered in the aws-encryption-provider component of the pkg/plugin/plugin.go file at revision 4341c70. The vulnerability caused the V1Plugin.Decrypt function to panic when passed an empty ciphertext, crashing the entire gRPC server process. This was due to the function...

CVE-2020-8897

A weak robustness vulnerability exists in the AWS Encryption SDKs for Java, Python, C and Javalcript prior to versions 2.0.0. Due to the non-committing property of AES-GCM and other AEAD ciphers such as AES-GCM-SIV or XChaCha20Poly1305 used by the SDKs to encrypt messages, an attacker can craft a...
