Security readout for executives and security teams
Plain-English summary
CVE-2026-15502 is a SQL injection issue in AojiaoZero Antaris 1.0’s PayPal IPN payment handler. A remote authenticated attacker could manipulate payment-related input and potentially read or alter database data. Business urgency is moderate, especially where Antaris handles transactions or customer records.
Executive priority
Treat as a medium-priority application risk. Prioritize environments processing payments or sensitive customer data, because database compromise could affect transaction integrity and confidentiality. Lack of vendor response increases remediation uncertainty.
Technical view
The reported flaw affects _rewardPurchase in /ipn.php, where the item_number argument is not safely handled, leading to SQL injection. VulDB lists network access, low attack complexity, and required authentication. CVSS v2 score is 6.5. The vendor reportedly did not respond to disclosure.
Likely exposure
Exposure is likely limited to organizations running AojiaoZero Antaris 1.0 with the PayPal IPN payment handler reachable by authenticated users or payment workflow actors.
Exploitation context
The source bundle does not show CISA KEV listing or confirmed active exploitation. VulDB indicates remote exploitation is possible and permissions are required. Public details identify the affected file, function, and parameter, but no vendor-confirmed fix is listed.
Researcher notes
Evidence is primarily from VulDB and CVE records. The advisory names Antaris 1.0, /ipn.php, _rewardPurchase, and item_number. Authentication is required per CVSS. No patch, workaround, or active exploitation confirmation is provided in the supplied sources.
Mitigation direction
- Identify any AojiaoZero Antaris 1.0 deployments and owners.
- Restrict access to /ipn.php to required payment infrastructure where feasible.
- Monitor payment handler and database logs for unusual item_number activity.
- Check vendor or project channels for updated guidance or patched releases.
- Consider disabling affected PayPal IPN functionality if business impact allows.
Validation and detection
- Confirm whether Antaris 1.0 is deployed in production or staging.
- Verify whether /ipn.php is externally reachable.
- Review code handling of item_number in _rewardPurchase.
- Check logs for abnormal payment notification requests.
- Document compensating controls around payment callback endpoints.
