SSRF yields internal-request confidentiality exposure (C:L); PR:L reflects that a CKEditor attachment handler is typically reachable only within an authenticated editing context; no direct integrity or availability impact.

3DescriptionCVE.org
A flaw has been found in WuzhiCMS up to 4.1.0. The impacted element is the function ckditor::saveRemote of the file coreframe/app/attachment/index.php of the component Remote Image Fetch. This manipulation of the argument source[] causes server-side request forgery. The attack can be initiated remotely. The exploit has been published and may be used. The project was informed of the problem early through an issue report but has not responded yet.
AnalysisAI
Server-side request forgery in WuzhiCMS up to and including version 4.1.0 lets an attacker direct the server to fetch an arbitrary URL through the ckditor::saveRemote handler in coreframe/app/attachment/index.php, by manipulating the source[] argument of the Remote Image Fetch component. Publicly available exploit code exists (a public GitHub issue, wuzhicms/wuzhicms#221, documents the flaw) and the vendor was notified early but has not responded, so no fixed release is available at time of analysis. …

Vulnerability AssessmentAI
| Exploitation | Exploitation requires reaching the Remote Image Fetch feature - specifically the ckditor::saveRemote function in coreframe/app/attachment/index.php - and supplying an attacker-controlled URL via the source[] argument, which the server then fetches (classic SSRF). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 base score of 6.9 (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L) reflects a remotely reachable, low-complexity SSRF requiring no privileges or interaction, tempered by uniformly LOW impact ratings - a scoring pattern characteristic of VulDB's automated triage that tends to spread impact evenly across VC/VI/VA rather than reflecting SSRF's true confidentiality-dominant profile. … 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 or fixed version is identified at time of analysis - the project was notified via wuzhicms/wuzhicms#221 but has not responded, so there is no official upgrade target (track https://github.com/wuzhicms/wuzhicms/ and https://vuldb.com/vuln/405512 for a fix). … Detailed patch versions, workarounds, and compensating controls in full report. |
