Summary
Lithium vulnerable to Cross Site Scripting in provided Swagger-UI
Impact
A XSS vulnerability in the provided (outdated) Swagger-UI is exploitable in applications using lithium with Swagger-UI enabled.
This allows an attacker gain Remote Code Execution (RCE) and potentially exfiltrate secrets in the context of this swagger session.
Patches
The used swagger-ui was updated by switching to the latest version of dropwizard-swagger in 8b9b406d608fe482ec0e7adf8705834bca92d7df
Workarounds
The risk of injected external content can be reduced by setting up a Content-Security-Policy.

Impact
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.
GHSA-F36P-42JV-8RH2 has a CVSS score of 8.1 (High). The vector is network-reachable, no 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 (3.4.2); upgrading removes the vulnerable code path.

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.

Frequently Asked Questions
- What is GHSA-F36P-42JV-8RH2? GHSA-F36P-42JV-8RH2 is a high-severity cross-site scripting (XSS) vulnerability in com.wire:lithium (maven), affecting versions < 3.4.2. It is fixed in 3.4.2. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
- How severe is GHSA-F36P-42JV-8RH2? GHSA-F36P-42JV-8RH2 has a CVSS score of 8.1 (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.
- Which packages are affected by GHSA-F36P-42JV-8RH2?
com.wire:lithium(maven) (versions < 3.4.2)com.wire.bots:lithium(maven) (versions < 3.4.2)
- Is there a fix for GHSA-F36P-42JV-8RH2? Yes. GHSA-F36P-42JV-8RH2 is fixed in 3.4.2. Upgrade to this version or later.
- Is GHSA-F36P-42JV-8RH2 exploitable, and should I be worried? Whether GHSA-F36P-42JV-8RH2 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 GHSA-F36P-42JV-8RH2 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.
