postgresql

Covert timing channel in comparison of MD5-hashed password in PostgreSQL authentication allows an attacker to recover user credentials sufficient to authenticate.  This does not affect scram-sha-256 passwords, the default in all supported releases.  However, current databases may have MD5-hashed passwords originating in upgrades from PostgreSQL 13 or earlier.  Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected.

CVE-2026-6478 is a medium-severity vulnerability in PostgreSQL that arises from a covert timing channel in the comparison of MD5-hashed passwords during authentication. An attacker can exploit this timing side channel to recover user credentials remotely, enabling unauthorized database access. This vulnerability does not affect scram-sha-256 password hashes, which are the default in all supported PostgreSQL releases. However, databases upgraded from PostgreSQL 13 or earlier may still use MD5-hashed passwords and thus remain vulnerable. Red Hat has issued security advisories and patches for affected PostgreSQL versions, particularly for PostgreSQL 13 on Red Hat Enterprise Linux 8. The recommended mitigation is to migrate all user passwords away from MD5 hashing by altering passwords, which updates the hash to the stronger scram-sha-256 method.
