CVE-2026-41514

OP-TEE affects Cortex-A TrustZone, with RSA-OAEP decryption in the Hisilicon HPRE driver vulnerable from v4.5.0 up to v4.11.0 due to non-constant-time memcmp() in label hash verification and multiple distinct error paths. This creates a padding oracle allowing plaintext recovery on ~1,000–2,000 a...

CVE-2026-59099

Apereo CAS 7.3.0 before 8.0.0-RC6 contains a cryptographic vulnerability that allows remote unauthenticated attackers to recover plaintext conversation state by exploiting AES-GCM initialization vector reuse across the server lifetime. Attackers can collect multiple client-side webflow execution...

Apereo CAS 7.3.0 before 8.0.0-RC6 contains a cryptographic vulnerability that allows remote unauthenticated attackers to recover plaintext conversation state by exploiting AES-GCM initialization vector reuse across the server lifetime. Attackers can collect multiple client-side webflow execution...

CVE-2026-59099

Apereo CAS: vulnerability in 7.3.0 prior to 8.0.0-RC6 due to AES-GCM IV reuse across server lifetime, enabling remote unauthenticated attackers to recover plaintext webflow conversation state by known-plaintext analysis on multiple client-side webflow tokens collected from the unauthenticated log...

CVE-2026-56369

ImageMagick before 7.1.2-22 contains an information disclosure vulnerability in the PasskeyEncipherImage method due to AES-CTR nonce reuse. Attackers can exploit nonce reuse in the cipher implementation to recover plaintext information from encrypted images...

Linux Distros Unpatched Vulnerability : CVE-2026-55967

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - AES-GCM encryption/decryption with extremely large cumulative single message sizes 64 GiB were not properly rejected by the streaming APIs, allowing counter wra...

CVE-2026-39031

Lansweeper lsrunase 2.0 and lsencrypt 2.0 use RC4 encryption with a hardcoded 142-byte static key array to encrypt credentials. An 8-character prefix is stored in cleartext alongside the ciphertext. This allows an attacker with local access to recover any encrypted password to plaintext using a...

CVE-2026-55967

CVE-2026-55967 covers AES-GCM streaming APIs that fail to reject extremely large cumulative single messages (>64 GiB), allowing counter wrap and keystream reuse and enabling plaintext recovery. Public documents reference the same issue across multiple OS advisories (Ubuntu, Debian, Debian-deri...

Astra Linux – Vulnerability in mbedtls

A issue was discovered in Mbed TLS 2.x before 2.28.7, and in 3.x before 3.5.2. There was a timing-related side channel in RSA private operations. This side channel could allow a local attacker to recover the plaintext. It required the attacker to send a large number of messages for decryption, as...

Astra Linux – Vulnerability in OpenSSL

There exists a timing-based side channel in the OpenSSL RSA Decryption implementation. This vulnerability could be sufficient for an attacker to recover plaintext across a network in a Bleichenbacher-style attack. To successfully decrypt data, an attacker would need to be able to send a very larg...

Astra Linux – Vulnerability in libgcrypt20

The ElGamal implementation in Libgcrypt before version 1.9.4 allows plaintext recovery. This occurs because, during interaction between two cryptographic libraries, a dangerous combination of elements arises—specifically, the prime number defined by the receiver’s public key, the generator define...

PT-2026-45997

Mercusys AC12G EU V1 router with firmware AC12GEU V1 200909 uses a static authentication nonce that does not change between requests from the same source IP. Combined with the predictable XOR-based password encoding securityEncode function, this allows an attacker to reverse captured authenticati...

Unity Linux 20.1060e / 20.1070e Security Update: libgcrypt (UTSA-2026-017437)

The Unity Linux 20 host has a package installed that is affected by a vulnerability as referenced in the UTSA-2026-017437 advisory. The ElGamal implementation in Libgcrypt before 1.9.4 allows plaintext recovery because, during interaction between two cryptographic libraries, a certain dangerous...

Use of a Broken or Risky Cryptographic Algorithm

Overview org.bouncycastle:bcprov-jdk14 is a Java implementation of cryptographic algorithms. Affected versions of this package are vulnerable to Use of a Broken or Risky Cryptographic Algorithm due to the generateCTR process in G3413CTRBlockCipher. An attacker can recover relationships between...

EUVD-2026-21235

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...

Improper Validation of Integrity Check Value

Overview Affected versions of this package are vulnerable to Improper Validation of Integrity Check Value via the PKCS7 CBC decryption process. An attacker can recover plaintext data by sending repeated decryption queries with modified ciphertext, exploiting improper validation of interior paddin...
