It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-34462 in the wild and no public exploit code.\n\nAffected product: sandboxie-plus Sandboxie. No package-level version data is available, so check the vendor advisory linked from the reference page.\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/CVE-2026-34462/ (Markdown: https://insights.sbomify.com/CVE-2026-34462/index.md)","id":"CVE-2026-34462","markdown":"https://insights.sbomify.com/CVE-2026-34462/index.md","name":"CVE-2026-34462","record":{"aliases":["GHSA-9cjg-vh9m-hhx4"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","privilege_escalation"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows sandbox software","requires_auth":"low_privilege","summary":"Local attackers can trigger a stack buffer overflow in Sandboxie-Plus to achieve SYSTEM code execution or service denial.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"sandboxie","vendor":"sandboxie-plus"}],"cvss":{"score":7.3,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-170","name":"Improper Null Termination"},{"id":"CWE-121","name":"Stack-based Buffer Overflow"}],"description":"Sandboxie-Plus is an open source sandbox-based isolation software for Windows. In versions 1.17.2 and earlier, several ProcessServer handlers (KillAllHandler, SuspendAllHandler, and RunSandboxedHandler) copy a WCHAR boxname[34] field from request structures into WCHAR[40] stack buffers using wcscpy without verifying null termination. Because the service pipe accepts variable-length packets larger than the request structure, an attacker can fill the boxname field with non-zero data and append additional controlled wide characters after the structure. wcscpy then reads past the fixed field and overflows the destination stack buffer. The service pipe is created with a NULL DACL, allowing any local process to connect, and the unsafe copy occurs before authorization checks. This can lead to a crash of the SbieSvc service or potential code execution as SYSTEM. This issue has been fixed in version 1.17.3.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Sandboxie-Plus ProcessServer boxname stack buffer overflows via unterminated wide string copy","id":"CVE-2026-34462","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"MantisBT has Stored HTML Injection/XSS via Clone Issue Form","id":"CVE-2026-34463"},"packages":[],"prev":{"headline":"Sandboxie-Plus SbieIniServer RunSbieCtrl stack buffer overflow allows local privilege escalation","id":"CVE-2026-34461"},"products":["Sandboxie"],"published":"2026-05-05","related":[{"cvss_score":10,"headline":"Security feature bypass in n/a","id":"CVE-2018-18748","kev_date_added":null,"published":"2018-10-28"},{"cvss_score":9.9,"headline":"Sandboxie's Integer Overflow in SbieIniServer::RC4Crypt allows sandbox escape and SYSTEM compromise","id":"CVE-2025-64721","kev_date_added":null,"published":"2025-12-11"},{"cvss_score":9.3,"headline":"Sandboxie-Plus privilege escalation via INI CRLF injection bypassing EditAdminOnly","id":"CVE-2026-34458","kev_date_added":null,"published":"2026-05-05"},{"cvss_score":9.2,"headline":"Path traversal in Sandboxie","id":"CVE-2024-49360","kev_date_added":null,"published":"2024-11-29"},{"cvss_score":8.8,"headline":"Sandboxie-Plus sandbox escape via uninitialized memory leak and stack overflow in GetRawInputDeviceInfoSlave","id":"CVE-2026-34459","kev_date_added":null,"published":"2026-05-05"},{"cvss_score":8.8,"headline":"Sandboxie-Plus NamedPipeServer OpenHandler stack overflow via unterminated server field","id":"CVE-2026-34464","kev_date_added":null,"published":"2026-05-05"},{"cvss_score":8.2,"headline":"Sandboxie kernel driver denial of service via malformed IOCTL from sandboxed process","id":"CVE-2026-32603","kev_date_added":null,"published":"2026-05-05"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-07","vendors":["sandboxie-plus"]},"summary":"Local attackers can trigger a stack buffer overflow in Sandboxie-Plus to achieve SYSTEM code execution or service denial.","url":"https://insights.sbomify.com/CVE-2026-34462/"}
