It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-34596 exists.\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-2026-34596/ (Markdown: https://insights.sbomify.com/CVE-2026-34596/index.md)","id":"CVE-2026-34596","markdown":"https://insights.sbomify.com/CVE-2026-34596/index.md","name":"CVE-2026-34596","record":{"aliases":["GHSA-xjvp-63f2-v585"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["privilege_escalation","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Windows sandbox software","requires_auth":"low_privilege","summary":"An attacker can exploit a race condition during addon installation to execute arbitrary code with SYSTEM privileges on Windows.","user_interaction":"required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[{"product":"sandboxie","vendor":"sandboxie-plus"}],"cvss":{"score":5.4,"severity":"medium","source":"cna","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-367","name":"Time-of-check Time-of-use (TOCTOU) Race Condition"}],"description":"Sandboxie-Plus is an open source sandbox-based isolation software for Windows. In versions 1.17.2 and earlier, a Time-of-Check-to-Time-of-Use (TOCTOU) race condition exists during addon installation. When a user installs an addon through the SandMan interface, UpdUtil.exe is spawned as SYSTEM by SbieSvc but stages files in the user-writable %TEMP%\\sandboxie-updater directory. After UpdUtil verifies file hashes against the signed addon manifest, install.bat extracts files.cab and executes config.exe from its contents. Between hash verification and extraction, an unprivileged user can replace files.cab with a crafted cabinet containing a malicious executable, which is then run as SYSTEM. No UAC prompt is required.\n\nThis 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":"weaponised"},"has_fix":false,"headline":"Sandboxie-Plus local privilege escalation via TOCTOU race condition in UpdUtil addon installation","id":"CVE-2026-34596","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"race_condition","year":"2026"},"n_packages":0,"n_references":1,"next":{"headline":"Coolify: Authenticated Host RCE","id":"CVE-2026-34597"},"packages":[],"prev":{"headline":"Parse Server: LiveQuery protected-field guard bypass via array-like logical operator value","id":"CVE-2026-34595"},"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":"poc","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-05-07","vendors":["sandboxie-plus"]},"summary":"An attacker can exploit a race condition during addon installation to execute arbitrary code with SYSTEM privileges on Windows.","url":"https://insights.sbomify.com/CVE-2026-34596/"}
