High [CVE-2026-45822] Denial of Service via crafted input
CVE-2026-45822Source published Source updated
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. A flaw was found in the `decode-uri-component` library. This vulnerability allows a remote attacker to trigger a Denial of Service (DoS) by submitting specially crafted input. The `decode()` function, when processing a large number of encoded URI components, consumes excessive CPU resources, which can lead to the application becoming unresponsive and unavailable.

- Mitigation guidance
- Validate and limit the length of any user-controlled input before passing it to decode-uri-component's decode() function. Inputs containing more than approximately 200 percent-encoded tokens (e.g. '%ab' sequences) can trigger noticeable delays. Reject or truncate URI components exceeding a reasonable length threshold before decoding. A fix exists in the upstream repository (commit fa479daf) but has not yet been included in an npm release.
