HighCVSS 8.7 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 34/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.39% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: github.com/zitadel/zitadel (Go) 1.80.0-v2.20.0.20260717062331-baf6ed501b68.
  • Mentioned 1 time in Turkish national cyber security advisories (siberguvenlik.gov.tr).

Low priority for now. Upgrade to github.com/zitadel/zitadel (Go) 1.80.0-v2.20.0.20260717062331-baf6ed501b68 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

ZITADEL is an open source identity management platform. From 3.0.0 until 3.4.13 and 4.16.1, ZITADEL Actions V1 enables the goja Node-compatible require() registry without restricting its filesystem source loader. An organization Action author with ORG_OWNER, org.action.write, and org.flow.write permissions can run JavaScript at OIDC, SAML, and login-flow trigger points and load files readable by the ZITADEL server process. This can disclose mounted configuration and secrets, including credentials stored through ZITADEL_FIRSTINSTANCE_LOGINCLIENTPATPATH or ZITADEL_FIRSTINSTANCE_MACHINEKEYPATH, and recovered bootstrap credentials can enable escalation from an organization administrator to an instance administrator. The issue affects Actions V1, and host command execution is not established. This issue is fixed in versions 3.4.13 and 4.16.1.
