Which packages are affected by CVE-2024-49757?

CVE-2024-49757 affects the following packages: github.com/zitadel/zitadel (Go), github.com/zitadel/zitadel (Go), github.com/zitadel/zitadel (Go), github.com/zitadel/zitadel (Go), github.com/zitadel/zitadel (Go), github.com/zitadel/zitadel (Go). Ecosystems affected: Go.

How do I fix CVE-2024-49757?

Update github.com/zitadel/zitadel to 2.63.5 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2024-49757 is resolved across your whole dependency graph.

How do I detect CVE-2024-49757 in my Go dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for github.com/zitadel/zitadel. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.

How do I mitigate CVE-2024-49757 if there is no patch (or I can't update yet)?

If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.

How does O3 Security protect against CVE-2024-49757?

O3 pinpoints whether CVE-2024-49757 is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.

Is CVE-2024-49757 actively exploited in the wild?

No public exploit code has been indexed for CVE-2024-49757 yet. This does not mean the vulnerability cannot be exploited — absence of public exploits does not imply safety. Apply the recommended fix and use O3 Security to monitor your exposure.

What is the EPSS score for CVE-2024-49757?

CVE-2024-49757 has an EPSS (Exploit Prediction Scoring System) score of 2.6%, placing it in the 83th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. This score indicates relatively lower exploitation probability, though the CVSS severity should still guide your patching priority.

Is there exploit tooling available for CVE-2024-49757?

A Nuclei detection template exists for CVE-2024-49757, meaning automated scanners can fingerprint it. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was CVE-2024-49757 published, and has it been updated?

CVE-2024-49757 was published on October 25, 2024 and was last updated on April 10, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.

Description

The open-source identity infrastructure software Zitadel allows administrators to disable the user self-registration. Due to a missing security check in versions prior to 2.64.0, 2.63.5, 2.62.7, 2.61.4, 2.60.4, 2.59.5, and 2.58.7, disabling the "User Registration allowed" option only hid the registration button on the login page. Users could bypass this restriction by directly accessing the registration URL (/ui/login/loginname) and register a user that way. Versions 2.64.0, 2.63.5, 2.62.7, 2.61.4, 2.60.4, 2.59.5, and 2.58.7 contain a patch. No known workarounds are available.
