Chacha20Poly1305 key-encryption algorithm discards the Poly1305 authentication tag, performing no authentication on decryption

Impact The experimental Chacha20Poly1305 key-encryption algorithm generates the 16-byte Poly1305 authentication tag during encryptKey but discards it: the tag is never written to the header and therefore never reaches the wire. On the receiving side, decryptKey calls...

Astra Linux – Vulnerability in python-cryptography

A flaw was discovered in the python-cryptography package. This issue may allow a remote attacker to decrypt captured messages in TLS servers that use RSA key exchanges, which could result in the exposure of confidential or sensitive data...

github.com/go-jose/go-jose/v3: github.com/go-jose/go-jose/v4: Go JOSE: Denial of Service via crafted JSON Web Encryption (JWE) object

A flaw was found in Go JOSE, a library for handling JSON Web Encryption JWE objects. A remote attacker could exploit this vulnerability by providing a specially crafted JWE object. When decrypting such an object, if a key wrapping algorithm is specified but the encrypted key field is empty, the...

Uncaught Exception

Overview Affected versions of this package are vulnerable to Uncaught Exception in the decryption process when chunking is performed at certain boundaries. An attacker can cause decryption failures and trigger exceptions by manipulating the way encrypted data is chunked and processed. Note: This ...

PT-2026-38599

Name of the Vulnerable Software and Affected Versions MAXHUB Pivot client versions prior to 1.36.2 Description An issue in the application allows an attacker to obtain encrypted tenant email addresses and related metadata from any tenant. Because a hardcoded AES key Advanced Encryption Standard, ...

kernel: crypto: algif_aead - Fix minimum RX size check for decryption

A flaw was found in the Linux kernel, specifically within the algifaead module. The vulnerability involves an incorrect check for the minimum receive buffer size during decryption, which did not properly account for the tag size. This could potentially lead to issues with data integrity or...

CVE-2026-41244 Mojic: Observable Timing Discrepancy in HMAC Verification

Mojic is a CLI tool to transform readable C code into an unrecognizable chaotic stream of emojis. Prior to 2.1.4, the CipherEngine uses a standard equality operator !== to verify the HMAC-SHA256 integrity seal during the decryption phase. This creates an Observable Timing Discrepancy CWE-208,...

DEBIAN-CVE-2026-5479

In wolfSSL's EVP layer, the ChaCha20-Poly1305 AEAD decryption path in wolfSSLEVPCipherFinal and related EVP cipher finalization functions fails to verify the authentication tag before returning plaintext to the caller. When an application uses the EVP API to perform ChaCha20-Poly1305 decryption,...

CVE-2026-32877

Botan is a C++ cryptography library. From version 2.3.0 to before version 3.11.0, during SM2 decryption, the code that checked the authentication code value C3 failed to check that the encoded value was of the expected length prior to comparison. An invalid ciphertext can cause a heap over-read o...

CVE-2026-32877 Botan: Heap Buffer Over-read in SM2 Decryption via Undersized C3 Hash Field

Botan is a C++ cryptography library. From version 2.3.0 to before version 3.11.0, during SM2 decryption, the code that checked the authentication code value C3 failed to check that the encoded value was of the expected length prior to comparison. An invalid ciphertext can cause a heap over-read o...

PT-2026-29124

Name of the Vulnerable Software and Affected Versions Botan versions 2.3.0 through 3.10.9 Description Botan is a C++ cryptography library. During SM2 decryption, the code that checks the authentication code value C3 does not verify the encoded value's length before comparison. This can lead to a...

CVE-2026-33204

A flaw was found in SimpleJWT, a PHP library for JSON Web Tokens. An unauthenticated attacker can exploit this vulnerability by tampering with JSON Web Encryption JWE headers when Password-Based Key Derivation Function 2 PBES2 algorithms are in use. This can lead to a Denial of Service DoS if an...

CVE-2026-32614 Go ShangMi SM9 Infinity-Point Ciphertext Forgery Vulnerability

Go ShangMi Commercial Cryptography Library GMSM is a cryptographic library that covers the Chinese commercial cryptographic public algorithms SM2/SM3/SM4/SM9/ZUC.
