CVE-2025-46815: ZITADEL Allows IdP Intent Token Reuse

HighCVSS 8.0 · v3.1—No exploit Fix available

Noroxi assessment

Priority: Monitor (action score 32/100)

  • 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: 0.47% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. A user must open a link or visit a page. Special conditions such as timing or configuration are required.
  • Fixed version: github.com/zitadel/zitadel (Go) 2.71.9, 3.0.0, 2.70.10; govulncheck-vulndb (openSUSE:Tumbleweed) 0.0.20250515T200012-1.1.

Low priority for now. Upgrade to github.com/zitadel/zitadel (Go) 2.71.9, 3.0.0, 2.70.10; govulncheck-vulndb (openSUSE:Tumbleweed) 0.0.20250515T200012-1.1 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

The identity infrastructure software ZITADEL offers developers the ability to manage user sessions using the Session API. This API enables the use of IdPs for authentication, known as idp intents. Following a successful idp intent, the client receives an id and token on a predefined URI. These id and token can then be used to authenticate the user or their session. However, prior to versions 3.0.0, 2.71.9, and 2.70.10, it was possible to exploit this feature by repeatedly using intents. This allowed an attacker with access to the application’s URI to retrieve the id and token, enabling them to authenticate on behalf of the user. It's important to note that the use of additional factors (MFA) prevents a complete authentication process and, consequently, access to the ZITADEL API. Versions 3.0.0, 2.71.9, and 2.70.10 contain a fix for the issue. No known workarounds other than upgrading are available.
