Prior to this release, a user could craft a leaky operator that bypassed view access control lists (ACLs) and bypassed row security policies in partitioning or table inheritance hierarchies. Reachable statistics data notably included histograms and most-common-values lists. CVE-2017-7484 and CVE-2019-10130 intended to close this class of vulnerability, but this gap remained.

An attack requires the application to use SET ROLE , SET SESSION AUTHORIZATION , or an equivalent feature. The problem arises when an application query uses parameters from the attacker or conveys query results to the attacker. If that query reacts to current_setting('role') or the current user ID, it may modify or return data as though the session had not used SET ROLE or SET SESSION AUTHORIZATION . The attacker does not control which incorrect user ID applies. Query text from less-privileged sources is not a concern here, because SET ROLE and SET SESSION AUTHORIZATION are not sandboxes for unvetted queries.

CVE-2023-2455 and CVE-2016-2193 fixed most interaction between row security and user ID changes. They missed cases where a subquery, WITH query, security invoker view, or SQL-language function references a table with a row-level security policy. This has the same consequences as the two earlier CVEs. That is to say, it leads to potentially incorrect policies being applied in cases where role-specific policies are used and a given query is planned under one role and then executed under other roles. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLEs.\n\nApplying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications. This affects only databases that have used CREATE POLICY to define a row security policy. An attacker must tailor an attack to a particular application's pattern of query plan reuse, user ID changes, and role-specific row security policies.

This leads to potentially incorrect policies being applied in cases where role-specific policies are used and a given query is planned under one role and then executed under other roles. This scenario can happen under security definer functions or when a common user and query is planned initially and then re-used across multiple SET ROLE s. Applying an incorrect policy may permit a user to complete otherwise-forbidden reads and modifications. This affects only databases that have used CREATE POLICY to define a row security policy.\n\nThe PostgreSQL project thanks Wolfgang Walther for reporting this

Some don't adhere to the documented rule to target only objects known to be extension members already. An attack requires permission to create non-temporary objects in at least one schema, ability to lure or wait for an administrator to create or update an affected extension in that schema, and ability to lure or wait for a victim to use the object targeted in CREATE OR REPLACE or CREATE IF NOT EXISTS . Given all three prerequisites, the attacker can run arbitrary code as the victim role, which may be a superuser. Known-affected extensions include both PostgreSQL-bundled and non-bundled extensions.
