"value": "El panel de administraci\u00f3n de Pluck CMS se basa \u00fanicamente en una comparaci\u00f3n del encabezado Referer (requestedByTheSameDomain() en data/inc/functions.admin.php, que controla cada acci\u00f3n de admin.php) para la protecci\u00f3n CSRF, sin ning\u00fan token anti-CSRF por solicitud en ninguna parte del \u00e1rea de administraci\u00f3n. Cuando una solicitud no lleva informaci\u00f3n de Referer/Host, la rama elseif de la funci\u00f3n devuelve true, tratando la solicitud como del mismo origen. Debido a que una p\u00e1gina de atacante de sitio cruzado puede suprimir el encabezado Referer (por ejemplo, a trav\u00e9s de menor quemeta name=referrer content=no-referrermayor que), puede forzar al navegador de un administrador autenticado a enviar acciones de administraci\u00f3n falsificadas sin un Referer v\u00e1lido, incluyendo la creaci\u00f3n de p\u00e1ginas con HTML sin procesar (XSS almacenado a trav\u00e9s de la p\u00e1gina renderizada) e instalando m\u00f3dulos/temas PHP (ejecuci\u00f3n remota de c\u00f3digo)."

Nomenclature
- Seen: The vulnerability was mentioned, discussed, or observed by the user.
- Confirmed: The vulnerability has been validated from an analyst's perspective.
- Published Proof of Concept: A public proof of concept is available for this vulnerability.
- Exploited: The vulnerability was observed as exploited by the user who reported the sighting.
- Patched: The vulnerability was observed as successfully patched by the user who reported the sighting.
- Not exploited: The vulnerability was not observed as exploited by the user who reported the sighting.
- Not confirmed: The user expressed doubt about the validity of the vulnerability.
- Not patched: The vulnerability was not observed as successfully patched by the user who reported the sighting.

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.
