Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-47213 exists.\n\nAffected packages and fixed versions:\n- boxlite (PyPI): affected all versions up to 0.8.2; no fix listed\n- boxlite (PyPI): affected all versions up to 0.8.2; no fix listed\n- boxlite (PyPI): affected all versions up to 0.8.2; no fix listed\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-2026-47213/ (Markdown: https://insights.sbomify.com/CVE-2026-47213/index.md)","id":"CVE-2026-47213","markdown":"https://insights.sbomify.com/CVE-2026-47213/index.md","name":"CVE-2026-47213","record":{"aliases":["GHSA-xjhv-pp2r-6f82","PYSEC-2026-2400"],"analysis":{"component_type":"container_or_infrastructure","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Sandboxing service","requires_auth":"low_privilege","summary":"Malicious code in Boxlite sandboxes can bypass timeouts by catching SIGALRM, causing resource exhaustion and service unavailability.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"GitHub_M","cpe":[],"cvss":{"score":6.5,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-404","name":"Improper Resource Shutdown or Release"}],"description":"Boxlite is a sandbox service that allows users to create lightweight virtual machines (Boxes) and launch OCI containers within them to run untrusted code. In versions 0.8.2 and prior, Boxlite allows users to configure a timeout for services running inside the virtual machine. When the timeout is triggered, Boxlite sends a signal to kill the process. However, instead of using the uncatchable SIGKILL signal, Boxlite uses the catchable SIGALRM signal. Malicious code running inside the sandbox can exploit this vulnerability to continue running after the timeout is triggered, leading to resource exhaustion within the virtual machine and affecting the availability of the Boxlite service. This issue has been patched via commit 28159fc.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":false,"headline":"BoxLite: Timeout Bypass Vulnerability","id":"CVE-2026-47213","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":3,"n_references":2,"next":{"headline":"Docling: Unsafe URI and Path Handling in HTML Backend","id":"CVE-2026-47214"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.8.2"],"package":"boxlite","purl":null,"source":"GHSA-xjhv-pp2r-6f82"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.8.2"],"package":"boxlite","purl":"pkg:pypi/boxlite","source":"GHSA-xjhv-pp2r-6f82"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.8.2"],"package":"boxlite","purl":"pkg:pypi/boxlite","source":"PYSEC-2026-2400"}],"prev":{"headline":"Symfony: Twilio SMS Notifier allows unauthenticated webhook injection due to missing X-Twilio-Signature verification","id":"CVE-2026-47212"},"products":["boxlite"],"published":"2026-06-10","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-06-11","vendors":["boxlite-ai"]},"summary":"Malicious code in Boxlite sandboxes can bypass timeouts by catching SIGALRM, causing resource exhaustion and service unavailability.","url":"https://insights.sbomify.com/CVE-2026-47213/"}
