Published Mar 10, 2026CWE-918EPSS 0.39%

Overview

CVE-2026-30953 is a high-severity vulnerability. It was published on March 10, 2026 and has a CVSS 3.1 base score of 7.7 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.7, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
