Invenio-Communities has a Cross-Site Scripting (XSS) vulnerability in React components

GHSA-hjx6-f647-mvf9

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (invenio-communities 7.8.0, 4.2.2, 2.8.11), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

Source description

As published by the source; long descriptions are shortened.

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. Credits Thanks to Twitter.com/AliGoodLuck11 for reporting the vulnerability with a detailed description on how to reproduce it!

# Patch Next advisory brief: GHSA-hjx6-f647-mvf9

Advisory: Invenio-Communities has a Cross-Site Scripting (XSS) vulnerability in React components
IDs: GHSA-hjx6-f647-mvf9
Record: https://patchnext.com/advisories/ghsa-hjx6-f647-mvf9 (revision 2, source checked 26 Oct 2026, 13:16 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.3)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: invenio-communities 7.8.0, 4.2.2, 2.8.11. A vendor fix does not mean a deployment is fixed.

## Affected components
- PyPI invenio-communities: affected >= 5.0.0, < 7.8.0; >= 3.0.0, < 4.2.2; < 2.8.11; fixed in 4.2.2, 7.8.0, 2.8.11

## Suggested inspection (read-only)
- `python -m pip show invenio-communities`: prints the installed version. Run with the environment that serves production active.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on invenio-communities.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.
