How to fix?

Upgrade SLES:16.0.0 php8-pgsql to version 8.4.26-160000.1.1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream php8-pgsql package and not the php8-pgsql package as distributed by SLES. See How to fix? for SLES:16.0.0 relevant fixed versions and status.

PHP's OpenSSL stream peer verification checks the certificate's subjectAltName entries first and, whenever no entry matches, falls back to the Common Name. RFC 6125 requires the CN to be ignored once the certificate presents any service identity, so a certificate carrying a non-matching DNS SAN was still accepted when its CN matched the requested peer_name. A certificate trusted by the client for one name can therefore be used to impersonate another.
