AnalysisAI

Cross-site request forgery in light0011 cms (rolling-release, at minimum through commits c774dce3 and f72cf46f) allows a remote attacker to perform unauthorized state-changing operations on behalf of an authenticated CMS user by inducing that user to visit a malicious page. A public proof-of-concept is documented in GitHub issue #12, and the project maintainer has not responded to the disclosure, leaving the vulnerability unpatched. …

Vulnerability AssessmentAI

Exploitation The victim must have an active authenticated session in light0011 cms at the time they are induced to visit the attacker-controlled page - unauthenticated users carry no exploitable session context. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P, score 5.3) is internally consistent: network-reachable, low complexity, no attacker privileges, but passive user interaction required and impact limited to low integrity. … 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 No vendor-released patch is available at time of analysis; the project maintainer has not responded to the GitHub issue disclosure at https://github.com/light0011/cms/issues/12. … Detailed patch versions, workarounds, and compensating controls in full report.

Threat intelligence, references, and detailed analysis are available after sign-in.
