Public CVEs
Published vulnerabilities in this vendor's products, from the NVD.
No CVEs matched yet. We match NVD records by vendor name, so products sold under another name can be missing.
Original policy
Copied from hackerone.com on 12 Nov 2026. The summaries on this page are made from it; the live page may have changed since.
Disclosure Policy
- Please do not discuss this program or any vulnerabilities (even resolved ones) outside of the program without express consent from the organization.
- Follow HackerOne's disclosure guidelines.
Program Rules
- Please provide detailed reports with reproducible steps. If the report is not detailed enough to reproduce the issue, the issue may not be marked as triaged.
- Submit one vulnerability per report unless you need to chain vulnerabilities to provide impact.
- When duplicates occur, we only triage the first report received (provided that it can be fully reproduced).
- Multiple vulnerabilities caused by one underlying issue will be treated as one valid report.
- Some of the assets in scope may be mirror sites for the most part, duplicated vulnerabilities will be grouped.
- Social engineering (e.g. phishing, vishing, smishing) is prohibited.
- No DoS/DDoS testing.
- Submitting contact forms in which the researcher is not in control of both the sender and the recipient of the contact form.
- Make a good faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our service.
- Only interact with accounts you own or with explicit permission of the account holder.
- If you need to create public content, for example ads or public profile, please don't draw attention with the content.
- Please do not interact with other users. If you need to test user interactions please use test accounts under your control.
- Moving beyond “proof of concept” report steps (for example: proving that account takeover vulnerability with a dummy test account is acceptable, but not exploiting or accessing customer accounts)
- We've got the automated vulnerability scanners under control, thanks! Right now, what we really need is your brainpower, not just raw processing power. While automated tools are handy, we're looking for a bit more depth in the analysis. So, if you come across vulnerabilities, it would be awesome if you could provide some additional insights into why they're a concern.
