How severe is CVE-2023-46134?

CVE-2023-46134 has a CVSS score of 6.1/10, rated MEDIUM. Review your exposure and patch according to your risk tolerance.

Which packages are affected by CVE-2023-46134?

CVE-2023-46134 affects the following packages: dtale (PyPI). Ecosystems affected: PyPI.

How do I fix CVE-2023-46134?

Update dtale to 3.7.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2023-46134 is resolved across your whole dependency graph.

How do I detect CVE-2023-46134 in my PyPI dependencies?

Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for dtale, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

How do I mitigate CVE-2023-46134 if there is no patch (or I can't update yet)?

Escape or sanitise the affected output on the server side rather than relying on client-side filtering, and add a Content-Security-Policy that blocks inline script execution so injected markup cannot run even if it reaches the page.

Is CVE-2023-46134 actively exploited in the wild?

No public exploit code has been indexed for CVE-2023-46134 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-2023-46134?

CVE-2023-46134 has an EPSS (Exploit Prediction Scoring System) score of 0.9%, placing it in the 58th 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.

What type of vulnerability is CVE-2023-46134?

This weakness type describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

When was CVE-2023-46134 published, and has it been updated?

CVE-2023-46134 was published on October 25, 2023 and was last updated on October 28, 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

Impact

Users hosting D-Tale publicly can be vulnerable to remote code execution allowing attackers to run malicious code on the server.

Patches

Users should upgrade to version 3.7.0 where the "Custom Filter" input is turned off by default. You can find out more information on how to turn it back on here

Workarounds

The only workaround for versions earlier than 3.7.0 is to only host D-Tale to trusted users.
