Cookie validation key forgery in liufee FeehiCMS up to 2.1.1 allows unauthenticated remote attackers to craft arbitrary signed cookies by exploiting a hardcoded (or empty) `cookieValidationKey` in the production backend configuration file `environments/prod/backend/config/main-local.php`. Because FeehiCMS is built on the Yii2 framework, this key is used for HMAC-based cookie integrity verification; a known or empty key trivially breaks that guarantee, enabling session/cookie forgery that can lead to authentication bypass and backend access. A public proof-of-concept exploit exists (FEHI-003-Empty-cookieValidationKey), and no vendor patch has been issued despite responsible disclosure through a GitHub issue.
Server-side request forgery in FeehiCMS up to version 2.1.1 allows authenticated high-privilege users to make the backend server issue arbitrary HTTP requests by manipulating the source[] parameter in the UEditor catchImage function. The CVSS 4.0 vector confirms network-reachable exploitation requiring high privileges (PR:H), limiting the attack surface to authenticated backend administrators. A public proof-of-concept writeup has been published on GitHub and the vendor has not responded to the responsible disclosure issue filed against the repository.
Unrestricted file upload in FeehiCMS up to version 2.1.1 allows unauthenticated remote attackers to upload arbitrary files through the UEditor widget endpoint (UeditorAction::init in backend/widgets/ueditor/UeditorAction.php). A named public proof-of-concept (FEHI-001-UEditor-Unauthorized-File-Upload) is available on GitHub, enabling straightforward exploitation. The vendor has not responded to the coordinated disclosure issue filed at GitHub, and no patch exists at time of analysis.
Server-side request forgery in FeehiCMS 2.1.1 and earlier exposes the bundled TimThumb image-processing script to unauthenticated remote exploitation via a crafted src parameter. An attacker can coerce the application server to issue arbitrary HTTP requests, enabling enumeration of internal network services and cloud metadata endpoints. Exploit code has been publicly disclosed per VulDB submission 718278; EPSS remains very low at 0.04% (14th percentile) and no CISA KEV entry exists, suggesting limited opportunistic exploitation at time of analysis.
FeehiCMS version 2.1.1 has a Remote Code Execution via Unrestricted File Upload in Ad Management. FeehiCMS version 2.1.1 allows authenticated remote attackers to upload files that the server later executes (or stores in an executable location) without sufficient validation, sanitization, or execution restrictions. An authenticated remote attacker can upload a crafted PHP file and cause the application or web server to execute it, resulting in remote code execution (RCE).
FeehiCMS version 2.1.1 fails to enforce server-side immutability for parameters that are presented to clients as "read-only." An authenticated attacker can intercept and modify the parameter in transit and the backend accepts the changes. This can lead to unintended username changes.
