CVE-2020-15146: Sylius Syliusresourcebundle

High severity, CVSS 8.8. EPSS: 2.1% chance of exploitation in the next 30 days.

In SyliusResourceBundle before versions 1.3.14, 1.4.7, 1.5.2 and 1.6.4, request parameters injected inside an expression evaluated by `symfony/expression-language` package haven't been sanitized properly. This allows the attacker to access any public service by manipulating that request parameter, allowing for Remote Code Execution. This issue has been patched for versions 1.3.14, 1.4.7, 1.5.2 and 1.6.4. Versions prior to 1.3 were not patched.

Affected products

• Sylius Syliusresourcebundle: up to and including 1.3.13; from 1.4.0, up to and including 1.4.6; from 1.5.0, up to and including 1.5.1; from 1.6.0, up to and including 1.6.3
