CVE-2026-55232

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. The attacker must also control the URL being fetched via the oEmbed proxy.

Blast radius

If exploited, the attacker could gain access to internal-only services and sensitive data, potentially leading to credential theft and further compromise.

Detection

No reliable host or network indicator is derivable from the published description.

Prioritized remediation

Upgrade to Vvveb version 1.0.8.6 or later.
