    CVE-2026-45822 (GCVE-0-2026-45822)

    Vulnerability from nvd – Published: 2026-06-30 08:05 – Updated: 2026-06-30 12:49
    VLAI
    Summary
    decode-uri-component through 0.4.1 is vulnerable to denial of service. The decode() function splits input on '%' producing N tokens and calls decodeComponents(), exhibiting super-linear parsing time: 200 '%ab' tokens takes approximately 0.7s, 700 tokens approximately 6s, and 1400 tokens approximately 33s. An attacker can cause significant CPU consumption and event-loop blocking via crafted input.
