{"cve":"CVE-2026-47213","nvd":{"published":"2026-06-10T23:16:48.323","modified":"2026-07-23T09:10:00.113","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-404"],"references":["https://github.com/boxlite-ai/boxlite/commit/28159fc5b6b6fd5037e18a58fc4644c882e3c581","https://github.com/boxlite-ai/boxlite/security/advisories/GHSA-xjhv-pp2r-6f82","https://github.com/boxlite-ai/boxlite/security/advisories/GHSA-xjhv-pp2r-6f82"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:38:48.522727527+00:00"},"epss":{"cve":"CVE-2026-47213","score":0.00268,"percentile":0.19041,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-xjhv-pp2r-6f82","url":"https://osv.dev/vulnerability/GHSA-xjhv-pp2r-6f82","summary":"BoxLite has a Timeout Bypass Vulnerability","modified":"2026-09-10T03:50:48.045090024Z","packages":[{"ecosystem":"PyPI","name":"boxlite","purl":"pkg:pypi/boxlite","ranges":["<=0.8.2"],"fixed":[]}]},{"id":"PYSEC-2026-2400","url":"https://osv.dev/vulnerability/PYSEC-2026-2400","summary":"BoxLite has a Timeout Bypass Vulnerability","modified":"2026-07-13T16:31:39.072050420Z","packages":[{"ecosystem":"PyPI","name":"boxlite","purl":"pkg:pypi/boxlite","ranges":["<=0.8.2"],"fixed":[]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
