CVE-2026-55232 · Severity: high · CVSS 7.6 · Published 2026-10-01

Vvveb is a CMS and page builder used to create websites and ecommerce stores. An authenticated admin user can exploit a flaw in the oEmbed proxy feature to read internal services and cloud metadata (including IAM credentials) by supplying IPv6 addresses or domains that lack IPv4 records, bypassing the application's private IP range protections.

## How to fix

- Fixed in 1.0.8.6

## Technical details

The SSRF vulnerability exists in Vvveb's oEmbed proxy, which performs server-side URL fetching and reflects the response. The vulnerability stems from an IPv4-only host resolution check that never inspects IPv6 addresses, allowing attackers to bypass private IP range validation. An authenticated admin-panel user (with site_admin role or higher) can craft requests using IPv6 literals or AAAA-only domains to access internal services and cloud metadata endpoints.

## Affected products
