{"id":"CVE-2026-30953","summary":"LinkAce affected by SSRF via link creation: NoPrivateIpRule not applied to LinkStoreRequest","details":"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.","aliases":["GHSA-f2mp-q78r-7jx7"],"modified":"2026-04-10T05:42:01.892304Z","published":"2026-03-10T20:38:48.381Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-918"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30953.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/30xxx/CVE-2026-30953.json"},{"type":"ADVISORY","url":"https://github.com/Kovah/LinkAce/security/advisories/GHSA-f2mp-q78r-7jx7"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-30953"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kovah/linkace","events":[{"introduced":"0"},{"last_affected":"57acf728640d4f48ed406faf561578f2328ad4c7"}],"database_specific":{"versions":[{"introduced":"0"},{"last_affected":"2.0.0"}]}}],"versions":["v0.0.1","v0.0.10","v0.0.11","v0.0.12","v0.0.13","v0.0.14","v0.0.15","v0.0.16","v0.0.17","v0.0.18","v0.0.19","v0.0.2","v0.0.20","v0.0.21","v0.0.22","v0.0.23","v0.0.24","v0.0.25","v0.0.26","v0.0.27","v0.0.28","v0.0.29","v0.0.3","v0.0.30","v0.0.31","v0.0.32","v0.0.33","v0.0.34","v0.0.35","v0.0.36","v0.0.37","v0.0.38","v0.0.39","v0.0.4","v0.0.40","v0.0.41","v0.0.42","v0.0.43","v0.0.44","v0.0.5","v0.0.6","v0.0.7","v0.0.8","v0.0.9","v1.0.0","v1.0.1","v1.1.0","v1.10.0","v1.10.1","v1.2.0","v1.2.1","v1.2.2","v1.3.0","v1.3.1","v1.4.0","v1.4.1","v1.5.0","v1.6.0","v1.6.1","v1.6.2","v1.6.3","v1.6.4","v1.7.0","v1.8.0","v1.8.1","v1.9.0","v1.9.1","v1.9.2","v2.0.0","v2.0.0-beta1","v2.0.0-beta2","v2.0.0-beta3","v2.0.0-beta4"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-30953.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:N/A:N"}]}
