Apostrophe has a Weak Password Recovery Mechanism for Forgotten Password and Improper Input Validation

Summary ApostropheCMS's password reset flow constructs the reset URL using req.hostname, which is derived directly from the attacker-controlled HTTP Host header when apos.baseUrl is not explicitly configured. An unauthenticated attacker who knows a victim's email address can send a crafted reset...

CVE-2026-6475

Symlink following in PostgreSQL pgbasebackup plain format and in pgrewind 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 orig...

CVE-2026-6475

Summary (CVE-2026-6475) : PostgreSQL suffers a symlink-following issue in the pg_basebackup plain format and in pg_rewind. An origin superuser can overwrite local files (for example, /var/lib/postgres/.bashrc), which could later be trusted when the server starts due to features like shared_preloa...
