FKIE_CVE-2026-120286

Vulnerability from fkie_nvd - Published: 2026-11-10 11:16 - Updated: 2026-11-10 11:16
Severity
5.3 (Medium) - CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:L/SC:N/SI:L/SA:N
Summary
Missing Authorization vulnerability in the device and deployment group pages in nerves-hub nerves_hub_web allows an authenticated organization member with the view role to change devices and deployment groups via LiveView events reserved for the manage role. The event handlers that add and delete device certificates, add and remove tags, overwrite or clear a device's manual location, remove a device from its deployment group, move matched devices into a deployment group or remove unmatched ones, import devices from a CSV, and start, retry or delete firmware delta builds carry out the change without calling authorized!/2, and the pages render the controls to every member. A view member can add a certificate that lets whoever holds its key connect as the device, delete a certificate so the device can no longer authenticate with it, and change which deployment group, and so which firmware release, a device receives. Everything stays within the organizations the member belongs to. This issue affects nerves_hub: from 1.0.0 before 2.5.3.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.

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.
