{"id":"CVE-2026-55232","published":"2026-10-01T19:17:21.900","lastModified":"2026-10-06T03:17:03.360","description":"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.","cvssScore":7.6,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:L/A:N","cwes":["CWE-918"],"vendors":[],"products":[],"references":[{"url":"https://github.com/givanz/Vvveb/commit/e27d1ef097a8502c33f8cc94271c948407c5dce3","tags":[]},{"url":"https://github.com/givanz/Vvveb/releases/tag/1.0.8.6","tags":[]},{"url":"https://github.com/givanz/Vvveb/security/advisories/GHSA-r6g4-5m3x-xrqj","tags":[]},{"url":"https://github.com/givanz/Vvveb/security/advisories/GHSA-r6g4-5m3x-xrqj","tags":[]}],"exploitRefs":[{"url":"https://github.com/givanz/Vvveb/commit/e27d1ef097a8502c33f8cc94271c948407c5dce3","tags":[]},{"url":"https://github.com/givanz/Vvveb/releases/tag/1.0.8.6","tags":[]},{"url":"https://github.com/givanz/Vvveb/security/advisories/GHSA-r6g4-5m3x-xrqj","tags":[]},{"url":"https://github.com/givanz/Vvveb/security/advisories/GHSA-r6g4-5m3x-xrqj","tags":[]}],"hasPoc":true,"ai":{"summary":"The vulnerability allows an authenticated admin to read internal services and cloud metadata, including IAM credentials, by exploiting the SSRF guard's handling of IPv6 addresses.","exploitability":"Exploitation requires an authenticated admin with site_admin or higher role and knowledge of the target's IPv6 address or domain with only an AAAA record.
