How severe is CVE-2022-23466?

CVE-2022-23466 has a CVSS score of 3.1 (Low). 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.

Which versions of teler.app are affected by CVE-2022-23466?

teler.app (go) versions >= 2.0.0-rc, <= 2.0.0-rc.3 is affected.

Is CVE-2022-23466 exploitable, and should I be worried?

Whether CVE-2022-23466 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.

What actually determines whether CVE-2022-23466 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.

How do I fix CVE-2022-23466?

Upgrade: teler.app to 2.0.0-rc.4 or later, teler.app to 2.0.0-dev.2 or later, teler.app to 0.0.0-20221203202318-20f59eda2420 or later, teler.app to 1.2.3-0.20221203202318-20f59eda2420 or later.

Summary

teler dashboard vulnerable to DOM-based cross-site scripting (XSS)

Description

teler prior to version <= 2.0.0-rc.4 is vulnerable to DOM-based cross-site scripting (XSS) in the teler dashboard. When teler requests messages from the event stream on the /events endpoint, the log data displayed on the dashboard are not sanitized.

Affected Version

This issue was introduced from version v2.0.0-rc to v2.0.0-rc.3 & v2.0.0-dev.

Workarounds

Here are some workarounds to handle this case:

Deactivate the live event dashboard from the configuration file, or
Upgrade teler version to v2.0.0-rc.4 or v2.0.0-dev.2 & above.

Impact

This only affects authenticated users and can only be exploited based on detected threats if the log contains a DOM scripting payload. This indicates a low severity and there is no significant impact on the users.

Untrusted input is rendered as active markup in a victim's browser, which can run script in their session. Typical impact: session or credential theft, and actions taken as the user.

CVE-2022-23466 has a CVSS score of 3.1 (Low). The vector is requires local access, high privileges required, and user interaction required. 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 (2.0.0-rc.4, 2.0.0-dev.2, 0.0.0-20221203202318-20f59eda2420, 1.2.3-0.20221203202318-20f59eda2420); upgrading removes the vulnerable code path.

Affected versions

teler.app (>= 2.0.0-rc, <= 2.0.0-rc.3) teler.app (= 2.0.0-dev) teler.app (>= 0.0.0-20220625162531-2289e90590a9, < 0.0.0-20221203202318-20f59eda2420) teler.app (>= 1.2.3-0.20220625162531-2289e90590a9, < 1.2.3-0.20221203202318-20f59eda2420)

Security releases

teler.app → 2.0.0-rc.4 (go) teler.app → 2.0.0-dev.2 (go) teler.app → 0.0.0-20221203202318-20f59eda2420 (go) teler.app → 1.2.3-0.20221203202318-20f59eda2420 (go)

Kodem intelligence

Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.

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. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.
