    CVE-2025-12758 (GCVE-0-2025-12758)

    Vulnerability from cvelistv5 – Published: 2025-11-27 05:00 – Updated: 2026-01-29 23:06
    VLAI
    Summary
    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.

    CVE-2025-56200 (GCVE-0-2025-56200)

    Vulnerability from cvelistv5 – Published: 2025-09-30 00:00 – Updated: 2025-09-30 19:36
    VLAI
    Summary
    A URL validation bypass vulnerability exists in validator.js through version 13.15.15. 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.
