CVE-2026-30953 Details
Description
LinkAce is a self-hosted archive to collect website links. When a user creates a link via POST /links, the server fetches HTML metadata from the provided URL (LinkRepository::create() calls HtmlMeta::getFromUrl()). The LinkStoreRequest validation rules do not include NoPrivateIpRule, allowing server-side requests to internal network addresses, Docker service hostnames, and cloud metadata endpoints. The project already has a NoPrivateIpRule class (app/Rules/NoPrivateIpRule.php) but it is only applied in FetchController.php (line 99), not in the primary link creation path.
A server-side request forgery (SSRF) vulnerability has been identified in LinkAce, a self-hosted link management application, in versions through 2.0.0. The issue arises during the link creation process, where the server fetches HTML metadata from user-provided URLs. The validation rules for the LinkStoreRequest do not include a check to block private IP addresses, allowing requests to internal network addresses, Docker service hostnames, and cloud metadata endpoints. Although LinkAce has a NoPrivateIpRule class, it is not applied in the main link creation workflow, leaving a gap that can be exploited.
To address this vulnerability, the NoPrivateIpRule should be added to the LinkStoreRequest, LinkUpdateRequest, and BulkStoreLinksRequest models.
