CVE-2018-10936 [HIGH] CWE-297 CVE-2018-10936: A weakness was found in postgresql-jdbc before version 42.2.5. It was possible to provide an SSL Fac A weakness was found in postgresql-jdbc before version 42.2.5. It was possible to provide an SSL Factory and not check the host name if a host name verifier was not provided to the driver. This could lead to a condition where a man-in-the-middle attacker could masquerade as a trusted server by providing a certificate for the wrong host, as long as it

CVE-2026-1933 [MEDIUM] CWE-284 CVE-2026-1933: A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read onl A flaw was found in Samba’s handling of NTFS-style reparse points on shares configured with read only = yes. Due to missing SMB-layer access checks, authenticated users with underlying filesystem write permissions may create or delete reparse point metadata through SMB operations even on read-only exports. This could allow modification of SMB-visible
