What is CVE-2026-105865?

In Payload CMS, an issue exists where authenticated users, authorized to update or delete uploads, can inadvertently trigger a cleanup process that removes files outside designated upload directories. This vulnerability, affecting all versions prior to 3.90.0 and canary versions before 4.0.0-canary.34, poses a risk of unintentional data loss and potential service interruption. The impact can be mitigated by restricting upload privileges to trusted users. Users are encouraged to upgrade to the latest versions to ensure their deployments are secure.
