Aliases: CVE-2025-56200 GHSA-9965-vmph-33xx |
validator.js has a URL validation bypass vulnerability in its isURL function A URL validation bypass vulnerability exists in validator.js prior to version 13.15.20. The isURL() function uses '://' as a delimiter to parse protocols, while browsers use ':' as the delimiter. This parsing difference allows attackers to bypass protocol and domain validation by crafting URLs leading to XSS and Open Redirect attacks. |

Validator is Vulnerable to Incomplete Filtering of One or More Instances of Special Elements Versions of the package validator before 13.15.22 are vulnerable to Incomplete Filtering of One or More Instances of Special Elements in the isLength() function that does not take into account Unicode variation selectors (\uFE0F, \uFE0E) appearing in a sequence which lead to improper string length calculation. This can lead to an application using isLength for input validation accepting strings significantly longer than intended, resulting in issues like data truncation in databases, buffer overflows in other system components, or denial-of-service. |

| VCID-36f4-22dx-47et | XSS Filter Bypass via Encoded URL The validator module for Node.js contains functionality meant to filter potential XSS attacks (a filter called xss). A method of bypassing the filter via an encoded URL has been publicly disclosed. In general, because the function’s filtering is blacklist-based it is likely that other bypasses will be discovered in the future. Developers are encouraged not to use the xss filter function in this package. ### Details: The xss() function removes the word "javascript" when contained inside an attribute. However, it does not properly handle cases where characters have been hex-encoded. As a result, it is possible to build an input that bypasses the filter but which the browser will accept as valid JavaScript. For example, browsers interpret `<a href="javascript:...">abc</a>` as `<a href="javascript:...">abc</a>`. |
