EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 7.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 62% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

No vendor fix yet — apply a workaround or compensating control (WAF / firewall / segmentation) and watch for a patch.

Backend administrators without system maintainer privileges were able to schedule any of the configuration:read, configuration:set, and configuration:show commands. This allowed them to modify arbitrary system configuration, which is normally limited to system maintainers. As a consequence, this allowed them, for example, to gain system maintainer privileges or cause a denial of service. Exploiting this vulnerability requires an administrator-level backend user account. This issue affects TYPO3 CMS versions 14.2.0-14.3.6.
