HestiaCP before 1.10.5 Protected Admin Bypass via Cron Job Creation

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

HestiaCP before 1.10.5 contains an authorization bypass vulnerability that allows non-ROOT_USER administrators to perform write actions while impersonating the protected ROOT_USER account. Attackers can log in via the loginas parameter and POST to /add/cron/, because the read-only flag is never checked, causing crond to run their commands as the protected administrator's system account.
