Does this matter?

Lower severity and a low EPSS score (0.50%). Track it; it rarely justifies an emergency change on its own.

Description

A security vulnerability has been detected in notionnext-org NotionNext up to 4.10.10. Affected by this issue is the function cleanCache of the file pages/api/cache.js of the component Authentication Guard. The manipulation of the argument token leads to missing authentication. The attack may be initiated remotely. Versions 4.1.0 - 4.9.5.2 allow unauthenticated exploitation due to missing method check. In versions 4.9.5.7 - 4.10.10 a guard present but only enforced when CACHE_REVALIDATION_TOKEN is set. Default deployments remain unprotected. The vendor was contacted early about this disclosure but did not respond in any way.
