CVE-2026-91924 Details
Description
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.
A vulnerability exists in pgweb versions through 0.17.0, where the POST /api/connect endpoint is left unprotected when connect-backend authorization is enabled. This flaw allows attackers to send arbitrary database connection strings, bypassing the intended resource-to-database mapping.

Users can update to pgweb version 0.17.1 or later, where this vulnerability has been addressed.
