Missing Encryption of Sensitive Data in PostgreSQL - CVE-2026-14663

Published: August 15, 2026


Vulnerability identifier: #VU142641
CSH Severity: Medium
CVSS v4: 6.9 [CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N]
CVE-ID: CVE-2026-14663
CWE-ID: CWE-311
Exploitation vector: Remote access
Exploit availability: No public exploit available

Vulnerability details

The vulnerability allows a remote attacker to disclose cleartext data and tamper with encrypted data.

The vulnerability exists due to improper encryption in pgcrypto functions when processing OpenSSL-disabled ciphers. A remote attacker can observe faulty ciphertext or supply encrypted input to disclose cleartext data and tamper with encrypted data.

The OpenSSL version and configuration determine which ciphers are disabled, and decryption may succeed even with the wrong key.
