{"id":"CVE-2026-55232","summary":"Vvveb: Server-side request forgery in Vvveb via IPv6 bypass of validateUrl() in editor oEmbed proxy","details":"Vvveb is a powerful and easy to use CMS with page builder to build websites, blogs or ecommerce stores. Prior to version 1.0.8.6, Vvveb's SSRF guard resolves a host with an IPv4-only function and never inspects IPv6, so any host that lacks an A record passes a private-range check. Editor oEmbed proxy fetches an attacker-supplied URL server side and reflects a response body, so an authenticated admin-panel user (default role site_admin or higher) can read internal-only services and cloud metadata, including IAM credentials, using an IPv6 literal or a domain that carries only an AAAA record. This issue has been patched in version 1.0.8.6.","aliases":["GHSA-r6g4-5m3x-xrqj"],"modified":"2026-10-02T03:47:28.525377201Z","published":"2026-10-01T18:43:19.102Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55232.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-918"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/55xxx/CVE-2026-55232.json"},{"type":"FIX","url":"https://github.com/givanz/Vvveb/commit/e27d1ef097a8502c33f8cc94271c948407c5dce3"},{"type":"WEB","url":"https://github.com/givanz/Vvveb/releases/tag/1.0.8.6"},{"type":"ADVISORY","url":"https://github.com/givanz/Vvveb/security/advisories/GHSA-r6g4-5m3x-xrqj"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-55232"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/givanz/vvveb","events":[{"introduced":"0"},{"fixed":"e27d1ef097a8502c33f8cc94271c948407c5dce3"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"1.0.8.6"}],"source":"AFFECTED_FIELD"}}],"versions":["1.0.8.5","1.0.8.4","1.0.8.3","1.0.8.2","1.0.8.1","1.0.8","1.0.7.3","1.0.7.2","1.0.7.1","1.0.7","1.0.6","1.0.5","1.0.4","1.0.3","1.0.2","1.0.1","1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-55232.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:L/A:N"}]}
