CVE-2026-91924: Sosedoff Pgweb

High severity, CVSS 8.5. EPSS: 0.4% chance of exploitation in the next 30 days.

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.

Affected products

• Sosedoff Pgweb: up to and including 0.17.0
