| CVE | Summary | Severity | Published |
|---|---|---|---|
| CVE-2018-16135 | The Opera Mini application 47.1.2249.129326 for Android allows remote attackers to spoof the Location Permission dialog via a crafted web site. | Medium 6.5 | 26 Dec 2022 |
| CVE-2021-23253 | Opera Mini for Android below 53.1 displays URL left-aligned in the address field. This allows a malicious attacker to craft a URL with a long domain name, e.g. www.safe.opera.com.attacker.com.
