An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of GHSA-f87w-3j5w-v58p in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- CefSharp.OffScreen (NuGet): affected all versions; fixed in 134.3.90\n- CefSharp.OffScreen (NuGet): affected all versions; fixed in 134.3.90\n- CefSharp.OffScreen.NetCore (NuGet): affected all versions; fixed in 134.3.90\n- CefSharp.OffScreen.NetCore (NuGet): affected all versions; fixed in 134.3.90\n- CefSharp.WinForms (NuGet): affected all versions; fixed in 134.3.90\n- CefSharp.WinForms (NuGet): affected all versions; fixed in 134.3.90\n- CefSharp.WinForms.NetCore (NuGet): affected all versions; fixed in 134.3.90\n- CefSharp.WinForms.NetCore (NuGet): affected all versions; fixed in 134.3.90\n- CefSharp.Wpf (NuGet): affected all versions; fixed in 134.3.90\n- CefSharp.Wpf (NuGet): affected all versions; fixed in 134.3.90\n- CefSharp.Wpf.HwndHost (NuGet): affected all versions; fixed in 134.3.90\n- CefSharp.Wpf.HwndHost (NuGet): affected all versions; fixed in 134.3.90\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/GHSA-f87w-3j5w-v58p/ (Markdown: https://insights.sbomify.com/GHSA-f87w-3j5w-v58p/index.md)","id":"GHSA-f87w-3j5w-v58p","markdown":"https://insights.sbomify.com/GHSA-f87w-3j5w-v58p/index.md","name":"GHSA-f87w-3j5w-v58p","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"CefSharp library","requires_auth":"none","summary":"Remote attackers can escape the sandbox and execute code via a malicious file in CefSharp on Windows.","user_interaction":"required","vuln_class":"privilege_escalation"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"Incorrect handle provided in unspecified circumstances in Mojo in Google Chrome on Windows prior to 134.0.6998.177 allowed a remote attacker to perform a sandbox escape via a malicious file.
