A vulnerability was identified in appsmithorg appsmith up to 1.97. Impacted is the function computeDisallowedHosts of the file app/server/appsmith-interfaces/src/main/java/com/appsmith/util/WebClientUtils.java of the component Dashboard. Such manipulation leads to server-side request forgery. The attack may be launched remotely. The exploit is publicly available and might be used. Upgrading to version 1.99 is recommended to address this issue. The affected component should be upgraded. The vendor was contacted early, responded in a very professional manner and quickly released a fixed version of the affected product.

Vulnerability AssessmentAI
| Risk Assessment | CVSS 6.9 with vector AV:N/AC:L/PR:N indicates remote, unauthenticated attack with low complexity and moderate impact (confidentiality, integrity, and availability all rated low). … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An unauthenticated attacker discovers a publicly exposed Appsmith Dashboard instance and crafts a malicious request targeting the computeDisallowedHosts function with a specially formatted URL parameter designed to bypass host validation. The attack exploits insufficient filtering to redirect the server's outbound connection to an internal service such as a cloud metadata endpoint (AWS IMDSv1), internal API, or database server. … |
| Remediation | Vendor-released patch: upgrade Appsmith to version 1.99 or later. … Detailed patch versions, workarounds, and compensating controls in full report. |
