CVE-2020-15169: Action View Project Action View

Medium severity, CVSS 6.1. EPSS: 2.4% chance of exploitation in the next 30 days.

In Action View before versions 5.2.4.4 and 6.0.3.3 there is a potential Cross-Site Scripting (XSS) vulnerability in Action View's translation helpers. Views that allow the user to control the default (not found) value of the `t` and `translate` helpers could be susceptible to XSS attacks. When an HTML-unsafe string is passed as the default for a missing translation key named html or ending in _html, the default string is incorrectly marked as HTML-safe and not escaped. This is patched in versions 6.0.3.3 and 5.2.4.4. A workaround without upgrading is proposed in the source advisory.

Affected products

• Action View Project Action View: before 5.2.4.4 (fixed in 5.2.4.4); from 6.0.0.0, before 6.0.3.3 (fixed in 6.0.3.3)
• Debian Debian Linux: version 10.0 only
• Fedoraproject Fedora: version 33 only
