What is GHSA-V4Q9-437P-MHPG?

GHSA-V4Q9-437P-MHPG is a high-severity cross-site scripting (XSS) vulnerability in leantime/leantime (composer), affecting versions < 3.3. It is fixed in 3.3. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.

Which versions of leantime/leantime are affected by GHSA-V4Q9-437P-MHPG?

leantime/leantime (composer) versions < 3.3 is affected.

Is there a fix for GHSA-V4Q9-437P-MHPG?

Yes. GHSA-V4Q9-437P-MHPG is fixed in 3.3. Upgrade to this version or later.

Is GHSA-V4Q9-437P-MHPG exploitable, and should I be worried?

Whether GHSA-V4Q9-437P-MHPG 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-V4Q9-437P-MHPG 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.

Summary

Leantime allows Cross Site Scripting (XSS) and SQL Injection (SQLi)

A cross-site scripting (XSS) vulnerability has been identified in Leantime. The vulnerability allows an attacker to inject malicious scripts into certain fields, potentially leading to the execution of arbitrary code or unauthorized access to user-sensitive information. The code does not include any validation or sanitization of the $_GET["id"] parameter. As a result, it directly incorporates the user-supplied value into the source path without any checks.

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.

Affected versions

leantime/leantime (< 3.3)

Security releases

leantime/leantime → 3.3 (composer)

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.
