Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
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.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · high confidence

PostgreSQL versions before 12.4, 11.9, and 10.14 fail to properly sanitize the search_path during logical replication. An authenticated attacker can exploit this to execute arbitrary SQL commands in the context of the replication user, similar to CVE-2018-1058.

MitigationUpgrade PostgreSQL to version 12.4, 11.9, 10.14 or later to remediate the search_path sanitization flaw in logical replication.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify installed PostgreSQL version
    Run `psql --version` or `SELECT version();` to determine the exact version number
    Affected if Version is 10.x before 10.14, 11.x before 11.9, or 12.x before 12.4
  2. Verify logical replication is configured
    Check for any publications or subscriptions: query `pg_publication` catalog or run `\dRp` in psql for publications and `\dRs` for subscriptions
    Affected if Logical replication publications or subscriptions exist on the database
  3. Confirm replication user privileges
    Query `SELECT rolname FROM pg_roles WHERE rolreplication = true;` to identify replication roles
    Affected if Any user has replication role privileges and the PostgreSQL version falls in the vulnerable range
  4. Inspect search_path setting
    Run `SHOW search_path;` as the replication user to verify current schema search path
    Affected if Search_path includes vulnerable schemas and logical replication is active on an affected version

You are affected if running PostgreSQL version 10.x before 10.14, 11.x before 11.9, or 12.x before 12.4 AND logical replication is configured with a replication user.
