CVE-2026-16253 — Total Upkeep < 1.17.3 - Unauthenticated Sensitive Data Disclosure and Forced Site Restore via Predictable cron_secret

CVE-2026-16253

Total Upkeep < 1.17.3 - Unauthenticated Sensitive Data Disclosure and Forced Site Restore via Predictable cron_secret PUBLISHED

Description (CNA)

The Total Upkeep WordPress plugin before 1.17.3 does not adequately protect the secret that authorizes its backup-restore functionality and exposes it to unauthenticated users, allowing them to disclose sensitive backup information and to force a full site restore that overwrites the live site's files and database. This is an incomplete fix of CVE-2020-36848, as the protection added at the time never took effect on distributed copies of the plugin.
