CVE-2026-92099: Unknown Wpgraphql Smart Cache

Medium severity, CVSS 6.5. EPSS: 0.3% chance of exploitation in the next 30 days.

The WPGraphQL Smart Cache WordPress plugin before 2.3.2 does not require authorisation or validate a caller-supplied query identifier before storing a persisted query from a request, allowing unauthenticated users to publish arbitrary query documents and claim query aliases before a site's own frontend registers them.

Affected products
