Plaintext disclosure via ignored cipher failures
Published Aug 13, 2026 · Updated Aug 13, 2026
Cleartext storage in PostgreSQL pgcrypto before 18.6, 17.11, 16.15, 15.19, and 14.24 allows remote attackers to recover plaintext. The PGP encryption code ignores OpenSSL cipher failures and XORs an unencrypted block with plaintext, producing a trivially reversible wrapper. Exposure requires pgcrypto use with a cipher disabled by the linked OpenSSL configuration; affected input also decrypts under a wrong key, defeating MDC authenticity checks.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=0 <14.24
- Affected versionversion=15 <15.19
- Affected versionversion=16 <16.15
- Affected versionversion=17 <17.11
- Affected versionversion=18 <18.5
