"value": "JupyterLab Desktop is the cross-platform desktop application for JupyterLab. Prior to 4.6.2-1, JupyterLab Desktop for macOS declared the com.apple.security.cs.allow-dyld-environment-variables entitlement, allowing the dynamic linker to honor DYLD_INSERT_LIBRARIES despite the hardened runtime. An attacker who can already execute code as the current user can load an arbitrary dynamic library into the JupyterLab Desktop process and inherit TCC permissions previously granted to the application, including access to protected Documents, Desktop, or Downloads folders without another macOS prompt. Exploitation requires existing local code execution and prior TCC grants; it does not provide initial or remote code execution. Windows and Linux are not affected. This vulnerability is fixed in 4.6.2-1."

"value": "JupyterLab Desktop es la aplicaci\u00f3n de escritorio multiplataforma para JupyterLab. Versiones anteriores a la 4.6.2-1 de JupyterLab Desktop para macOS declaraban el derecho com.apple.security.cs.allow-dyld-environment-variables, permitiendo que el enlazador din\u00e1mico respetara DYLD_INSERT_LIBRARIES a pesar del entorno de ejecuci\u00f3n reforzado. Un atacante que ya puede ejecutar c\u00f3digo como el usuario actual puede cargar una biblioteca din\u00e1mica arbitraria en el proceso de JupyterLab Desktop y heredar los permisos TCC previamente otorgados a la aplicaci\u00f3n, incluido el acceso a las carpetas protegidas de Documentos, Escritorio o Descargas sin otra solicitud de macOS. La explotaci\u00f3n requiere la ejecuci\u00f3n de c\u00f3digo local existente y concesiones TCC previas; no proporciona ejecuci\u00f3n de c\u00f3digo inicial ni ejecuci\u00f3n remota de c\u00f3digo. Windows y Linux no se ven afectados. Esta vulnerabilidad se corrige en la versi\u00f3n 4.6.2-1."

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.
