CVE-2026-27851
dovecot: Dovecot: SQL/LDAP injection via incorrect safe filter interpretation with variable expansion
Einstufung nach Quelle
Trivys eigenes Label ist CRITICAL. Kritisch laut NVD. Niedriger laut Red Hat (hoch), Ubuntu (mittel).
Beschreibung
When safe filter is used with variable expansion, all following pipelines on the same string are incorrectly interpreted as safe too, enabling unsafe data to be unescaped. This can enable SQL / LDAP injection attacks when used in authentication. Avoid using safe filter until on fixed version. No publicly available exploits are known.
