SCA: security update for github.com/zitadel/zitadel/v2 (GHSA-7777-fhq9-592v)

low Tenable Self-Hosted Container Security Plugin ID 438157

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - ZITADEL is an open source identity management platform. Zitadel Action V2 (introduced as early preview in
 2.59.0, beta in 3.0.0 and GA in 4.0.0) is a webhook based approach to allow developers act on API request
 to Zitadel and customize flows such the issue of a token. Zitadel's Action target URLs can point to local
 hosts, potentially allowing adversaries to gather internal network information and connect to internal
 services. When the URL points to a local host / IP address, an adversary might gather information about
 the internal network structure, the services exposed on internal hosts etc. This is sometimes called a
 Server-Side Request Forgery (SSRF). Zitadel Actions expect responses according to specific schemas, which
 reduces the threat vector. The patch in version 4.11.1 resolves the issue by checking the target URL
 against a denylist. By default localhost, resp. loopback IPs are denied. Note that this fix was only
 released on v4.x. Due to the stage (preview / beta) in which the functionality was in v2.x and v3.x, the
 changes that have been applied to it since then and the severity, respectively the actual thread vector, a
 backport to the corresponding versions was not feasible. Please check the workaround section for
 alternative solutions if an upgrade to v4.x is not possible. If an upgrade is not possible, prevent
 actions from using unintended endpoints by setting network policies or firewall rules in one's own
 infrastructure. Note that this is outside of the functionality provided by Zitadel. (CVE-2026-27945)
