Description
Impact
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.
Patches
The problem has been patched in v7.8.0. Patches also have been backported in versions v4.2.2 and v2.8.11.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for invenio-communities, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update invenio-communities to 7.8.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-hjx6-f647-mvf9 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-hjx6-f647-mvf9 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-hjx6-f647-mvf9. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-hjx6-f647-mvf9 in your dependencies?
O3 Security finds GHSA-hjx6-f647-mvf9 across PyPI dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
