Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Xibo is an Open Source Digital Signage platform with a web content management system and Windows display player software. Session tokens are exposed in the return of session search API call on the sessions page. Subsequently they can be exfiltrated and used to hijack a session. Users must be granted access to the session page, or be a super admin. Users should upgrade to version 3.3.10 or 4.0.9 which fix this issue. Customers who host their CMS with the Xibo Signage service have already received an upgrade or patch to resolve this issue regardless of the CMS version that they are running. Patches are available for earlier versions of Xibo CMS that are out of security support: 2.3 patch ebeccd000b51f00b9a25f56a2f252d6812ebf850.diff. 1.8 patch a81044e6ccdd92cc967e34c125bd8162432e51bc.diff. There are no known workarounds for this vulnerability.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

How this class of weakness works · CWE-200

The application discloses data — error detail, internal paths, tokens, or other users' records — to someone who shouldn't see it. On its own it can look minor, but it hands attackers the map they need for a larger attack. Remediation is about minimising what's returned and enforcing authorization on every piece of data.

Recommended fix High confidence

3.3.10 (for 3.x branches) or 4.0.9 (for 4.x branches)

  1. Backup your current Xibo CMS installation and database before proceeding
  2. Determine your current Xibo CMS version (2.x, 3.x, or 4.x) to select the appropriate upgrade path
  3. For CMS 3.x users: Upgrade to version 3.3.10
  4. For CMS 4.x users: Upgrade to version 4.0.9
  5. Follow the official Xibo upgrade documentation for your version to apply the update
  6. After upgrade, verify the session page no longer exposes session tokens in the API response
  7. Customers hosted with Xibo Signage service have already received automatic patches
