IXP Manager: Broken Object-Level Authorization in API key management
Summary
IXP Manager is a web application for managing Internet Exchange Points. In versions before 7.3.0, an authenticated user can view and edit API key records belonging to other users, because the API key edit/update path does not verify ownership of the record. An attacker needs a valid low-privilege user account on the installation, and no user interaction is required.
Affected
- IXP Manager versions before 7.3.0 (according to the CNA record)
- Some sources list the range as up to 7.2.x; the CNA record is used here.
Fixed in
- Version 7.3.0 (and later releases that include the fix; confirm against the advisory)
Workaround
- No vendor workaround known. Apply the update.
- Limit user accounts and review who has portal access.
Exploitation
- No evidence of active exploitation known.
- No CISA KEV entry found.
- Public proof of concept: unconfirmed.
Our recommendation
- Upgrade IXP Manager to 7.3.0 or the latest supported release, and apply CVE-2026-63339 fixes at the same time.
- Rotate existing API keys after the upgrade, especially if you suspect another user accessed or changed a key.
- Review user accounts and remove unneeded access.
- Check whether the portal is internet-facing and restrict access where possible.
Public exploits
PoC-in-GitHub, Metasploit and Exploit-DB list nothing for this CVE.

Original description (NVD)
IXP Manager is a full-stack web application for managing Internet Exchange Points. Prior to version 7.3.0, an authenticated user can view and edit a resource belonging to another user without authorization. The API-key edit/update path in `ApiKeyController` selects records by identifier without checking that `user_id` matches the caller, allowing access to another user's API-key record. This issue is fixed in version 7.3.0.
