CVE-2026-58063

A flaw was found in Bouncy Castle for Java. A remote attacker can exploit this vulnerability by providing a specially crafted BCFKS keystore file that specifies an unbounded Key Derivation Function KDF cost. This can lead to a Denial of Service DoS as the system attempts to process the file,...

CVE-2026-15055

A flaw was found in Bouncy Castle for Java. An attacker could exploit this vulnerability by providing a specially crafted input to the PKCS8 / PBES2 decryptors. This input could specify an excessively high Key Derivation Function KDF cost, causing the decryptor to consume significant computationa...

Use of Password Hash With Insufficient Computational Effort

Overview openssl-encrypt is an A package for secure file encryption and decryption based on modern ciphers using heavy-compute-load chaining of hashing and KDF to generate strong encryption password based on users provided password to ensure secure encryption of files Affected versions of this...

CVE-2026-74888

opensslencrypt versions before 1.4.0 use a non-standard PBKDF2 key derivation construction with iterations=1 per call in an outer loop, creating a KDF whose security properties have not been formally analyzed. Attackers can exploit this weakened key derivation to more efficiently crack passwords...

PYSEC-2026-3976

opensslencrypt versions before 1.4.6 contain a key derivation flaw in sequential XOR composition mode where the last stage cancels out during key generation. When configured with a single KDF and no prior hashing stage, attackers can bypass memory-hard key derivation and perform offline password...

PYSEC-2026-3976

opensslencrypt versions before 1.4.6 contain a key derivation flaw in sequential XOR composition mode where the last stage cancels out during key generation.

CVE-2026-74888

The PHP package openssl_encrypt before 1.4.0 uses a non-standard PBKDF2 construction (iterations=1 per call) that weakens key derivation, enabling attackers to more efficiently crack passwords protecting legacy encrypted files. No in-the-wild exploitation is reported; upgrading to version 1.4.0 i...

CVE-2026-74871

opensslencrypt versions before 1.4.6 contain a key derivation flaw in sequential XOR composition mode where the last stage cancels out during key generation. When configured with a single KDF and no prior hashing stage, attackers can bypass memory-hard key derivation and perform offline password...

CVE-2026-74871

The jahlives/openssl_encrypt PHP package before 1.4.6 has a KDF bypass: in sequential XOR composition mode the final stage cancels out, so attackers with local access can crack passwords at SHA-256 speed instead of the configured memory-hard KDF cost. CVSS 6.2 (MEDIUM, local). No in-the-wild expl...

EUVD-2026-60090
