DescriptionCVE.org

Cleartext storage in PostgreSQL pgcrypto disabled ciphers allows a user to recover cleartext, via direct observation of the faulty ciphertext. The OpenSSL version and OpenSSL configuration determine the disabled ciphers. If the application accepts encrypted data as input, decryption will succeed even with the wrong key. This in turn loses the modest protection from the Modification Detection Code (MDC). Affected functions are pgp_sym_encrypt, pgp_sym_decrypt, pgp_pub_encrypt, pgp_pub_decrypt, pgp_sym_encrypt_bytea, pgp_sym_decrypt_bytea, pgp_pub_encrypt_bytea, and pgp_pub_decrypt_bytea. Versions before PostgreSQL 18.5, 17.11, 16.15, 15.19, and 14.24 are affected.

AnalysisAI

Cleartext storage in PostgreSQL's pgcrypto extension silently exposes PGP-encrypted data as recoverable plaintext when OpenSSL disables the requested cipher, affecting all eight PGP encryption and decryption functions (pgp_sym_encrypt/decrypt, pgp_pub_encrypt/decrypt, and their bytea variants) across PostgreSQL 14 through 18. Beyond confidentiality loss, the same code path defeats the Modification Detection Code (MDC) integrity check, allowing decryption to succeed with an incorrect key - enabling an attacker to inject attacker-controlled plaintext through applications that accept encrypted data as input. …

Vulnerability AssessmentAI

Exploitation Exploitation requires that the pgcrypto extension is installed and actively used in the target PostgreSQL instance, AND that at least one OpenSSL cipher used by the affected PGP functions has been explicitly disabled in the runtime OpenSSL configuration or is absent from the installed OpenSSL version - this is the critical, non-default prerequisite and the primary limiting factor. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The official CVSS 3.1 score of 6.5 with vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N warrants critical examination on the AC metric. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation The primary fix is to upgrade to PostgreSQL 18.5, 17.11, 16.15, 15.19, or 14.24, all of which contain the patch for CVE-2026-14663; the vendor advisory is at https://www.postgresql.org/support/security/CVE-2026-14663/. … Detailed patch versions, workarounds, and compensating controls in full report.
