PYSEC-2026-784 Microsoft: CBC Padding Oracle in Azure Blob Storage Encryption Library

Summary The Azure Storage Encryption library in Java and other languages is vulnerable to a CBC Padding Oracle attack, similar to CVE-2020-8911. The library is not vulnerable to the equivalent of CVE-2020-8912, but only because it currently only supports AES-CBC as encryption mode. Severity...

CVE-2026-50210

The device encrypts data using AES-CBC with static zero-filled Initialization Vectors IVs, making it susceptible to replay attacks and known-plaintext decryption...

CVE-2026-11347 Hardcoded Cryptographic Keys and Weak IV Generation in linqi

The linqi application contains hardcoded cryptographic keys. Additionally, the application uses a weak algorithm with a limited ASCII charset to dynamically generate Initialization Vectors IVs for AES/CBC encryption, making known-plaintext attacks feasible. An attacker with local access can...

CVE-2026-45787 electerm's encrypt method not safe enough

electerm is an open-sourced terminal/ssh/sftp/telnet/serialport/RDP/VNC/Spice/ftp client. Prior to 3.9.5, deterministic AES-192-CBC with a fixed zero IV, constant KDF salt, and no MAC leads to confidentiality and integrity failures for synced bookmark/profile data. Attackers can crack common...

CVE-2026-5039

CVE-2026-5039 affects TP-Link TL-WR841N v13. The issue stems from using DES-CBC encryption in the TDDPv2 debug protocol, with a cryptographic key derived from the device’s default web management credentials. This makes the key predictable when the device remains in its default configuration. A ne...

DEBIAN-CVE-2026-5504

A padding oracle exists in wolfSSL's PKCS7 CBC decryption that could allow an attacker to recover plaintext through repeated decryption queries with modified ciphertext. In previous versions of wolfSSL the interior padding bytes are not validated...
