CVE-2026-6478 May 14, 13:00 MEDIUM PATCH This Month

Timing-channel attack in PostgreSQL MD5 password authentication enables remote unauthenticated attackers to extract user credentials through statistical analysis of authentication response times, affecting versions prior to 18.4, 17.10, 16.14, 15.18, and 14.23. The vulnerability exploits variable-time comparison operations during MD5 password hash verification, but does not impact the default scram-sha-256 authentication method. Databases migrated from PostgreSQL 13 or earlier may retain MD5-hashed passwords and remain vulnerable despite running newer versions.

CVE-2026-5598 Apr 15, 09:05 Maven HIGH PATCH GHSA This Week

Non-constant time comparison operations in the Legion of the Bouncy Castle BC-JAVA cryptographic library (core modules, versions 2.17.3 through 1.83) expose FrodoKEM private keys to timing side-channel attacks, enabling remote unauthenticated attackers to extract cryptographic secrets through statistical analysis of operation timing variations. CVSS 4.0 score of 10.0 reflects maximum confidentiality and integrity impact across system and subsequent contexts. EPSS probability is low (0.04%, 14th percentile) and no active exploitation is confirmed, but SSVC framework rates this as automatable with total technical impact. Vendor patch available in BC-JAVA 1.84.

CVE-2025-69893 Apr 14, 15:16 MEDIUM This Month

BIP-39 mnemonic processing in Trezor One, Trezor T, and Trezor Safe firmware v1.13.0-v1.14.0 leaks seed phrase data via non-constant-time execution, enabling full mnemonic recovery by a physically present attacker during initial device setup. An adversary who can capture a single power or electromagnetic side-channel trace and apply a pre-trained Deep Learning Side-Channel Analysis (DL-SCA) model can reconstruct the BIP-39 mnemonic and subsequently derive all private keys, resulting in total loss of cryptocurrency assets. No public exploit code has been identified and no active exploitation is confirmed; Trezor has issued a patch per their published vulnerability advisory.

CVE-2025-66442 Apr 01, 00:00 MEDIUM This Month

Compiler-induced timing side channel in Mbed TLS through 4.0.0 and TF-PSA-Crypto through 1.0.0 allows information disclosure of RSA private keys and CBC/ECB-decrypted plaintext when LLVM's select-optimize feature is enabled during compilation. The vulnerability arises from compiler optimization that violates constant-time implementation guarantees, potentially exposing cryptographic material to timing analysis attacks despite developers' explicit use of constant-time code patterns.
