Collected exploitation and prediction evidence
Risk source coverageCISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.
No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Publisheddecode-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.

Published### Impact An attacker who can supply input to `decodeUriComponent()` (directly or via a dependency that uses this package on URL/query/path data) can cause excessive CPU usage and application unresponsiveness. This is an availability issue; there is no known memory corruption, data disclosure, or remote code execution impact. ### Patches Upgrade to `[email protected]`. ### Workarounds Limit the size of the input.
