Summary
The site title field at /panel/options/site/allows embedding JS tags, which can be used to attack all members of the system. This is a widespread attack and can cause significant damage if there is a considerable number of users.
Details
By embedding "<!--", the source code can be rendered non-functional, significantly impacting system availability. However, the attacker would need admin privileges, making the attack more difficult to execute.
Impact
The attack is widespread, leveraging what XSS can do. This will undoubtedly impact system availability.
GHSA-VF6X-59HH-332F has a CVSS score of 4.7 (Medium). The vector is network-reachable, high 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 (2.0.0-beta.4); 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.
Remediation advice
- Formwork 2.x (aa3e9c6) escapes site title from panel header navigation.
Frequently Asked Questions
- What is GHSA-VF6X-59HH-332F? GHSA-VF6X-59HH-332F is a medium-severity security vulnerability in getformwork/formwork (composer), affecting versions = 2.0.0-beta.3. It is fixed in 2.0.0-beta.4.
- How severe is GHSA-VF6X-59HH-332F? GHSA-VF6X-59HH-332F has a CVSS score of 4.7 (Medium). 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 getformwork/formwork are affected by GHSA-VF6X-59HH-332F? getformwork/formwork (composer) versions = 2.0.0-beta.3 is affected.
- Is there a fix for GHSA-VF6X-59HH-332F? Yes. GHSA-VF6X-59HH-332F is fixed in 2.0.0-beta.4. Upgrade to this version or later.
- Is GHSA-VF6X-59HH-332F exploitable, and should I be worried? Whether GHSA-VF6X-59HH-332F 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-VF6X-59HH-332F 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 GHSA-VF6X-59HH-332F? Upgrade
getformwork/formworkto 2.0.0-beta.4 or later.
