Description

When pglogical attempts to replicate data, it does not verify it is using a replication connection, which means a user with CONNECT access to a database configured for replication can execute the pglogical command to obtain read access to replicated tables. When pglogical runs it should verify it is running on a replication connection but does not perform this check. This vulnerability was introduced in the pglogical 3.x codebase, which is proprietary to EDB. The same code base has been integrated into BDR/PGD 4 and 5. To exploit the vulnerability the attacker needs at least CONNECT permissions to a database configured for replication and must understand a number of pglogical3/BDR specific commands and be able to decode the binary protocol.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

3 ≤ v < 3.7.26-ELS3
Affected range stops below 3.7.26-ELS, so it looks safe — our inference, not a vendor statement
4 ≤ v < 4.3.8-ELS5 ≤ v < 5.8.045
Affected range stops below 4.3.8-ELS, so it looks safe — our inference, not a vendor statement
Affected range stops below 5.8.0, so it looks safe — our inference, not a vendor statement
