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.
The product constructs all or part of an SQL command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended SQL command when it is sent to a downstream component. Without sufficient removal or quoting of SQL syntax in user-controllable inputs, the generated SQL query can cause those inputs to be interpreted as SQL instead of ordinary user data.
