CVE-2020-7071: Debian Linux

Medium severity, CVSS 5.3. EPSS: 2.9% chance of exploitation in the next 30 days.

In PHP versions 7.3.x below 7.3.26, 7.4.x below 7.4.14 and 8.0.0, when validating URL with functions like filter_var($url, FILTER_VALIDATE_URL), PHP will accept an URL with invalid password as valid URL. This may lead to functions that rely on URL being valid to mis-parse the URL and produce wrong data as components of the URL.

Affected products

• Debian Debian Linux: version 9.0 only; version 10.0 only
• Netapp Clustered Data Ontap: affected versions not specified
• PHP PHP: from 7.3.0, before 7.3.26 (fixed in 7.3.26); from 7.4.0, before 7.4.14 (fixed in 7.4.14); from 8.0.0, before 8.0.1 (fixed in 8.0.1)
