AI-suggested
Upgrade Strawberry GraphQL to version 0.315.4 or later, where this issue is patched. Until the upgrade is applied, avoid entering sensitive headers in the GraphiQL headers editor to prevent exposure via URL query strings. Patch status is confirmed by the vendor's versioning information indicating the fix in 0.315.4.
Description
Strawberry GraphQL is a library for creating GraphQL APIs. In versions 0.288.4 through 0.315.3, Strawberry's bundled GraphiQL template wrote values from the GraphiQL headers editor into the browser URL query string. If a user entered a sensitive header, such as `Authorization: Bearer <token>`, the value could become visible in browser history, copied links, and server/proxy/CDN access logs after a page reload or shared request. Version 0.315.4 patches the issue.
