WEBDYNE_CGI_AUTOESCAPE, which controls escaping of these values, defaults to off. From 2.022, WebDyne::HTML::Tiny also replaced its entity_encode method with one that returns its input unchanged, so enabling WEBDYNE_CGI_AUTOESCAPE has no effect.\n\nA remote attacker can inject script into any page using these tags through a crafted link.\n\n## Affected\n\n- `WebDyne >= 2.014 < 3.022`\n\n## Remediation\n\nUpgrade to WebDyne 3.022 or later.","depth":"sunlit","depthScore":3,"depthScoreParts":{"impact":2.8,"likelihood":0,"exploitation":0,"ransomware":0},"changes":[]}
