CVE ID :CVE-2026-6475 Published : May 14, 2026, 1 p.m. | 1 hour, 16 minutes ago Description :Symlink following in PostgreSQL pg_basebackup plain format and in pg_rewind allows an origin superuser to overwrite local files, e.g. /var/lib/postgres/.bashrc, that hijack the operating system account. It will remain the case that starting the server after these commands implicitly trusts the origin superuser, due to features like shared_preload_libraries. Hence, the attack has practical implications only if one takes relevant action between these commands and server start, like moving the files to a different VM or snapshotting the VM. Versions before PostgreSQL 18.4, 17.10, 16.14, 15.18, and 14.23 are affected. Severity: 8.8 | HIGH Visit the link for more details, such as CVSS details, affected products, timeline, and more...
