CVE-2026-94534: CWE-639 Authorization Bypass Through User-Controlled Key in dromara lamp-cloud
A vulnerability in dromara lamp-cloud up to version 5.10.0 allows authenticated users to bypass authorization controls on certain endpoints. Specifically, the PUT /anyone/baseInfo and PUT /anyone/avatar endpoints do not properly validate user identity, enabling attackers to modify arbitrary user profiles by supplying target user IDs in request bodies. This can lead to unauthorized changes to profile fields such as nickname, ID card, sex, nation, education, work description, and avatar attachments.
AI Analysis
Technical Summary
CVE-2026-94534 is an authorization bypass vulnerability in dromara lamp-cloud versions up to 5.10.0. The flaw exists because the application fails to validate the identity of the user making requests to the PUT /anyone/baseInfo and PUT /anyone/avatar endpoints. Authenticated attackers can exploit this by specifying arbitrary user IDs in the request body, allowing them to modify profile information of other users without proper authorization. This vulnerability is classified under CWE-639 (Authorization Bypass Through User-Controlled Key).
Potential Impact
The vulnerability allows authenticated attackers to modify the profile information of other users, including sensitive fields such as ID card data and avatar attachments. While confidentiality is not impacted, the integrity of user data is compromised, and availability impact is low. This can lead to unauthorized data manipulation and potential misuse of user identities within the affected system.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no patch or official fix information is provided, users should monitor the vendor's announcements for updates. In the meantime, restrict access to the affected endpoints to trusted users only and consider additional application-level access controls to prevent unauthorized profile modifications.
