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.","cvssScore":null,"cvssSeverity":null,"cvssVector":null,"cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://metacpan.org/release/ASPEER/WebDyne-3.022/changes","tags":[]}],"exploitRefs":[],"hasPoc":false,"ai":null}
