Upgrading to version 2.1.1 is capable of addressing this issue. Patch name: 67abfd864a15d169a78429f3290c91cb3b93e849. Upgrading the affected component is advised.

AnalysisAI

Code injection in yaojingang GEOFlow versions up to 2.1.0 allows a remote superadmin to execute arbitrary PHP on the server by submitting a malicious Blade template payload to the preview function of the Superadmin Theme Editor (SiteThemeEditorController.php). A publicly available proof-of-concept exploit has been disclosed via GitHub issue #60, and the attack requires no user interaction beyond the attacker's own authenticated session. …

Vulnerability AssessmentAI

Exploitation Exploitation requires an authenticated session with superadmin-level privileges in GEOFlow (CVSS PR:H) - standard administrator or lower-privilege roles cannot access the Superadmin Theme Editor and are insufficient to trigger this vulnerability. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The vendor-assigned CVSS 4.0 score of 2.0 reflects the PR:H (superadmin) prerequisite, which significantly limits the exploitable attack surface. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario Full exploit scenario with step-by-step reproduction available after sign-in.
Remediation Upgrade GEOFlow to version 2.1.1 immediately; this is the vendor-confirmed fix released at https://github.com/yaojingang/GEOFlow/releases/tag/v2.1.1 via commit 67abfd864a15d169a78429f3290c91cb3b93e849. … Detailed patch versions, workarounds, and compensating controls in full report.
