CVE-2024-31206

dectalk-tts Uses Unencrypted HTTP Request

Workarounds

There are no workarounds, but here are some precautions:

• Do not send any sensitive information.

• Carefully verify the API response before saving it.

Original report
Patch pull request

In [email protected], network requests to the third-party API are sent over HTTP, which is unencrypted. Unencrypted traffic can be easily intercepted and modified by attackers. Anyone who uses the package could be the victim of a man-in-the-middle (MITM) attack.

Theft

Because dectalk-tts is a text-to-speech package, user requests are expected to only contain natural language. The package README warns that user input is sent to a third-party API, so users should not send sensitive information regardless.

But if users ignore the warnings and send sensitive information anyway, that information could be stolen by attackers.

Modification

Attackers could manipulate requests to the API. However, the worst a modified request could do is return an incorrect audio file or bad request rejection.

Attackers could also manipulate responses from the API, returning malicious output to the user. Output is expected to be a wav-encoded buffer, which users will likely save to a file. This could be a dangerous entrypoint to the user's filesystem.

CVE-2024-31206 has a CVSS score of 8.2 (High). The vector is network-reachable, no privileges required, and no user interaction. A CVSS score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether this affects your application depends on whether the vulnerable code is present and reachable in your environment. A fixed version is available (1.0.1); upgrading removes the vulnerable code path.

The network request was upgraded to HTTPS in version 1.0.1. No other changes were made, so updating is risk-free.

1. What is CVE-2024-31206? CVE-2024-31206 is a high-severity security vulnerability in dectalk-tts (npm), affecting versions = 1.0.0. It is fixed in 1.0.1.
2. How severe is CVE-2024-31206? CVE-2024-31206 has a CVSS score of 8.2 (High). This score reflects the worst-case severity of the vulnerability, not your specific exposure. Whether it represents real risk in your environment depends on whether the vulnerable code is present and reachable.
3. Which versions of dectalk-tts are affected by CVE-2024-31206? dectalk-tts (npm) versions = 1.0.0 is affected.
4. Is there a fix for CVE-2024-31206? Yes. CVE-2024-31206 is fixed in 1.0.1. Upgrade to this version or later.
5. Is CVE-2024-31206 exploitable, and should I be worried? Whether CVE-2024-31206 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

6. What actually determines whether CVE-2024-31206 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
7. How do I fix CVE-2024-31206? Upgrade dectalk-tts to 1.0.1 or later.
