What happened

SharpEmu is an experimental PlayStation 5 emulator for Windows and Linux. In version 0.0.3-release.3 and earlier, the repository-provided debugger frontend tooling is vulnerable while running. This tooling is not included in the release archives. The frontend exposes an HTTP API on 127.0.0.1:8765 without authentication or CSRF token. Its  do_POST  handler in  tools/SharpEmu.DebuggerFrontend/debugger_frontend.

py  does not validate the Origin, Referer, Sec-Fetch-Site, or Host headers. The  _read_json_body()  function also accepts JSON sent with browser-simple content types instead of requiring  application/json . A malicious page that can reach the loopback listener can send cross-origin requests to  /api/launch ,  /api/command , and  /api/connect .

Chromium may require Local Network Access permission for pages served from public origins. Local-origin pages and other delivery paths are not consistently subject to this restriction. The  /api/launch  endpoint accepts an attacker-selected  emulatorPath  if it points to an existing file on the victim’s host. On POSIX systems, that file must also be executable.

The endpoint additionally requires an existing  ebootPath . The  /api/command  endpoint exposes debugger operations, including  write-memory ,  set-register , and  continue . The  /api/connect  endpoint can initiate outbound TCP connections.

These operations can let an attacker execute an existing binary with the victim’s privileges, control the attached emulated process, or reach network services accessible from the host. DNS rebinding can additionally let the attacker read API responses interactively. This issue is fixed in version 0.0.3-release.3-patch.1

About this data

This record was ingested from a data source. Retrieved: Nov 4, 2026, 17:45 UTC. Ingestion is not an independent editorial investigation.

NVD status: Received. Publication in the NVD is not evidence of exploitation.

A CISA KEV listing documents known exploitation, not necessarily a zero-day; absence from the catalog does not prove a vulnerability has never been exploited.

Technology tags indicate possible relevance, not verified exposure. Confirm the affected product, version, and configuration against your own inventory; KEVWire does not scan your systems.

A personal reading checklist on this device, not verified remediation.
