It was found that PostgreSQL versions before 12.4, before 11.9 and before 10.14 did not properly sanitize the search_path during logical replication
Summary
It was found that PostgreSQL versions before 12.4, before 11.9 and before 10.14
did not properly sanitize the search_path during logical replication. An
authenticated attacker could use this flaw in an attack similar to
CVE-2018-1058, in order to execute arbitrary SQL command in the context of
the user used for replication. (CVE-2020-14349)
It was found that some PostgreSQL extensions did not use search_path safely
in their installation script. An attacker with sufficient privileges could
use this flaw to trick an administrator into executing a specially crafted
script, during the installation or update of such extension. This affects
PostgreSQL versions before 12.4, before 11.9, before 10.14, before 9.6.19,
and before 9.5.23. (CVE-2020-14350)
