CVE-2017-11173 WRITEUP HIGH WRITEUP
rack-cors < 0.4.1 - Cross-Origin Resource Sharing Bypass via Regex Anchor Omission
Missing anchor in generated regex for rack-cors before 0.4.1 allows a malicious third-party site to perform CORS requests. If the configuration were intended to allow only the trusted example.com domain name and not the malicious example.net domain name, then example.com.example.net (as well as example.com-example.net) would be inadvertently allowed.
CVSS 8.8
CVE-2019-18978 WRITEUP MEDIUM WRITEUP
Rack CORS Middleware <1.0.4 - Path Traversal
An issue was discovered in the rack-cors (aka Rack CORS Middleware) gem before 1.0.4 for Ruby. It allows ../ directory traversal to access private resources because resource matching does not ensure that pathnames are in a canonical format.
CVSS 5.3
