El elemento afectado es una funci\u00f3n desconocida del archivo server.js del componente API Proxy Endpoint. Realizar una manipulaci\u00f3n del argumento Query resulta en falsificaci\u00f3n de petici\u00f3n del lado del servidor. El ataque puede ser iniciado remotamente. El exploit ha sido liberado al p\u00fablico y puede ser usado para ataques. Entrega continua con lanzamientos continuos es utilizada por este producto. Por lo tanto, no hay detalles de versi\u00f3n de lanzamientos afectados ni actualizados disponibles. El parche se llama 54f8f50f43af97c334a881af7b021e84b5b8310f.

Vulnerability timeline
Sightings and recorded dates, grouped by day · UTC
How durations are calculated
Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.
Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.

Vulnerabilities whose description is nearest to this one in the vector space of the CIRCL/vulnerability-attack-technique-biencoder model. This is a similarity search over the bi-encoder space (plain cosine), not a classification, and it has no measured accuracy.
