We have identified a Cross-Site Scripting (XSS) vulnerability within certain React components related to community members in the Invenio-Communities module. This vulnerability enables a user to inject a script tag into the Affiliations field during the account registration process. The malicious script is executed when the user creates a new community and is listed as a public member.

The script is triggered whenever any user visits the Members section of any community that includes the compromised user. This can potentially allow the attacker to access personal information, such as cookies, of the visiting user.

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-HJX6-F647-MVF9 has a CVSS score of 6.3 (Medium). The vector is network-reachable, low 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 (7.8.0, 4.2.2, 2.8.11); upgrading removes the vulnerable code path.

1. What is GHSA-HJX6-F647-MVF9? GHSA-HJX6-F647-MVF9 is a medium-severity cross-site scripting (XSS) vulnerability in invenio-communities (pip), affecting versions >= 5.0.0, < 7.8.0. It is fixed in 7.8.0, 4.2.2, 2.8.11. Untrusted input is rendered as active markup in a victim's browser, which can run script in their session.
2. How severe is GHSA-HJX6-F647-MVF9? GHSA-HJX6-F647-MVF9 has a CVSS score of 6.3 (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.
3. Which versions of invenio-communities are affected by GHSA-HJX6-F647-MVF9? invenio-communities (pip) versions >= 5.0.0, < 7.8.0 is affected.
4. Is there a fix for GHSA-HJX6-F647-MVF9? Yes. GHSA-HJX6-F647-MVF9 is fixed in 7.8.0, 4.2.2, 2.8.11. Upgrade to this version or later.
5. Is GHSA-HJX6-F647-MVF9 exploitable, and should I be worried? Whether GHSA-HJX6-F647-MVF9 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 GHSA-HJX6-F647-MVF9 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 GHSA-HJX6-F647-MVF9?
   • Upgrade invenio-communities to 7.8.0 or later
   • Upgrade invenio-communities to 4.2.2 or later
   • Upgrade invenio-communities to 2.8.11 or later
