CVE-2026-34560

CRITICAL

CI4MS: Logs Full Account Takeover for All-Roles & Privilege-Escalation via Stored DOM XSS

Title source: cna
STIX 2.1

Description

CI4MS is a CodeIgniter 4-based CMS skeleton that delivers a production-ready, modular architecture with RBAC authorization and theme support. Prior to version 0.31.0.0, the application renders user-controlled input unsafely within the logs interface. If any stored XSS payload exists within logged data, it is rendered without proper output encoding. This issue becomes a Blind XSS scenario because the attacker does not see immediate execution. Instead, the payload is stored within application logs and only executes later when an administrator views the logs page. This issue has been patched in version 0.31.0.0.
