"value": "dpaste is an open source pastebin application written in Python using the Django framework. A security vulnerability has been identified in the expires parameter of the dpaste API, allowing for a POST Reflected XSS attack. This vulnerability can be exploited by an attacker to execute arbitrary JavaScript code in the context of a user\u0027s browser, potentially leading to unauthorized access, data theft, or other malicious activities. Users are strongly advised to upgrade to dpaste release v3.8 or later versions, as dpaste versions older than v3.8 are susceptible to the identified security vulnerability. No known workarounds have been identified, and applying the patch is the most effective way to remediate the vulnerability."

Se ha identificado una vulnerabilidad de seguridad en el par\u00e1metro de caducidad de la API dpaste, lo que permite un ataque POST Reflected XSS. Un atacante puede aprovechar esta vulnerabilidad para ejecutar c\u00f3digo JavaScript arbitrario en el contexto del navegador de un usuario, lo que podr\u00eda provocar acceso no autorizado, robo de datos u otras actividades maliciosas. Se recomienda encarecidamente a los usuarios que actualicen a la versi\u00f3n v3.8 de dpaste o versiones posteriores, ya que las versiones de dpaste anteriores a la v3.8 son susceptibles a vulnerabilidad de seguridad identificada. No se han identificado workarounds conocidos y aplicar el parche es la forma m\u00e1s eficaz de remediar la vulnerabilidad."

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.

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.
