# CVE-2026-30953: LinkAce affected by SSRF via link creation: NoPrivateIpRule not applied to LinkStoreRequest

- Severity: CVSS 7.7 (High), CNA
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N
- CISA SSVC: exploitation=poc, automatable=no, technicalImpact=partial
- Known exploited (CISA KEV): no

## Affected

- Kovah LinkAce: through 2.0.0

## 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.
