Vulnerability AssessmentAI

Exploitation Exploitation requires the attacker to be authenticated with high-privilege access to the EyouCMS instance, as indicated by PR:H in the CVSS 4.0 vector. … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment Real-world risk is low despite the existence of a public POC. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
Exploit Scenario An attacker with high-privilege credentials - such as an administrator or content manager account - submits a crafted HTTP request to /index.php with a maliciously formed click_like parameter containing SQL injection syntax. Because the parameter is passed unsanitized to the database layer, the injected SQL executes in the context of the database user, allowing the attacker to read, modify, or delete records. …
Remediation No vendor-released patch has been identified at time of analysis; the maintainer has not responded to the responsible disclosure submitted via GitHub issue. … Detailed patch versions, workarounds, and compensating controls in full report.

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