CVE-2026-54239 FaustWP — Authentication Bypass via Initialization Vector Modification in Token Envelope

Faust.js is a headless WordPress toolkit. Prior to 1.8.11, the FaustWP WordPress plugin authenticates only the ciphertext in its token envelope and excludes the 16-byte initialization vector from the HMAC in WPE\FaustWP\Auth\encrypt and WPE\FaustWP\Auth\decrypt in...

Astra Linux – Vulnerability in LibreOffice

LibreOffice supports the storage of passwords for web connections in the user’s configuration database. The stored passwords are encrypted using a single master key provided by the user. There was a flaw in LibreOffice where the required initialization vector for encryption was always the same,...

Use Of A Broken Or Risky Cryptographic Algorithm

Spring Security is vulnerable to Use of a Broken or Risky Cryptographic Algorithm. The vulnerability is due to AesBytesEncryptor using AES/CBC with a null all-zero initialization vector, which allows an attacker to exploit predictable encryption and potentially infer relationships between encrypt...

kernel: crypto: ccp - copy IV using skcipher ivsize

A flaw was found in the Linux kernel's cryptographic coprocessor CCP driver. When processing AFALG rfc3686-ctr-aes-ccp requests, the ccpaescomplete function attempts to restore more data than the allocated buffer for the Initialization Vector IV can hold. This leads to a buffer overrun, which can...

kernel: crypto: seqiv - Do not use req->iv after crypto_aead_encrypt

A use-after-free vulnerability was found in the Linux kernel's seqiv Sequence IV crypto module. After calling cryptoaeadencrypt, the underlying request may be freed by asynchronous completion handlers. The code then incorrectly dereferences req-iv to compare against info, accessing potentially...

CVE-2026-71225

A flaw was found in libkcapi. When performing one-shot symmetric cipher operations on large inputs over 64 KiB in stateful modes such as Counter CTR or Cipher Block Chaining CBC, the library improperly reuses the Initialization Vector IV for each internal data chunk. A remote attacker could...

CVE-2026-71225

CVE-2026-71225 (libkcapi) : A flaw in libkcapi affects one-shot symmetric cipher operations for inputs over 64 KiB in stateful modes (CTR, CBC). The IV is incorrectly reused across internal data chunks, which can weaken confidentiality by exposing relationships in encrypted plaintext and may affe...

CVE-2026-71225 Libkcapi: iv reuse in libkcapi one-shot symmetric cipher chunking causes cipher state reset across chunk boundaries

A flaw was found in libkcapi. When performing one-shot symmetric cipher operations on large inputs over 64 KiB in stateful modes such as Counter CTR or Cipher Block Chaining CBC, the library improperly reuses the Initialization Vector IV for each internal data chunk. A remote attacker could...

NIP-04 parsing amplifies malformed ciphertext memory use

The NIP-04 decryption parser split attacker-controlled content on every ?iv= separator and collected all resulting segments before checking that the message had the expected two parts. It also Base64-decoded the complete IV text before checking that it represented the required 16-byte AES-CBC IV....

RUSTSEC-2026-0219 Remote Denial of Service via malformed NIP-04 IV

The nostr crate did not validate the length of the initialization vector decoded from the ?iv= portion of a NIP-04 encrypted message. The decoded IV was converted from a byte slice to the 16-byte AES-CBC IV type using a conversion that asserts the slice length. As a result, an IV whose decoded...
