What is CVE-2026-92099?

The WPGraphQL Smart Cache plugin prior to version 2.3.2 is susceptible to an authorization bypass vulnerability. This flaw allows unauthenticated users to store arbitrary query documents by exploiting the lack of validation for caller-supplied query identifiers. As a result, malicious users can publish unauthorized queries and take control of query aliases, which can lead to a compromised front-end experience on the affected WordPress sites.

Affected Version(s)

WPGraphQL Smart Cache 0 < 2.3.2

Exploit Proof of Concept (PoC)
