Original advisory

Published

pgweb through 0.17.0 leaves the POST /api/connect endpoint unguarded when connect-backend authorization is configured, allowing attackers to supply arbitrary database connection strings. Attackers can bypass the resource-to-database mapping by providing a custom session identifier and connection URL to access unauthorized databases and internal services.
