{"cve":"CVE-2026-32723","nvd":{"published":"2026-03-18T22:16:24.827","modified":"2026-06-17T10:36:16.383","status":"Analyzed","description":"SandboxJS is a JavaScript sandboxing library. Prior to 0.8.35, SandboxJS timers have an execution-quota bypass. A global tick state (`currentTicks.current`) is shared between sandboxes. Timer string handlers are compiled at execution time using that global tick state rather than the scheduling sandbox's tick object. In multi-tenant / concurrent sandbox scenarios, another sandbox can overwrite `currentTicks.current` between scheduling and execution, causing the timer callback to run under a different sandbox's tick budget and bypass the original sandbox's execution quota/watchdog. Version 0.8.35 fixes this issue.","cvss_v4":{"vector":"CVSS:4.0/AV:L/AC:L/AT:N/PR:L/UI:N/VC:N/VI:N/VA:L/SC:N/SI:N/SA:N","score":4.8},"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:N/I:N/A:H","score":4.7},"cwes":["CWE-362"],"references":["https://github.com/nyariv/SandboxJS/commit/cc8f20b4928afed5478d5ad3d1737ef2dcfaac29","https://github.com/nyariv/SandboxJS/security/advisories/GHSA-7p5m-xrh7-769r"],"products":["nyariv:sandboxjs"],"source":"nvd","synced_at":"2026-10-19T22:26:19.218427112+00:00"},"epss":{"cve":"CVE-2026-32723","score":0.00154,"percentile":0.04474,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-7p5m-xrh7-769r","url":"https://osv.dev/vulnerability/GHSA-7p5m-xrh7-769r","summary":"SandboxJS has an execution-quota bypass (cross-sandbox currentTicks race) in SandboxJS timers","modified":"2026-03-19T21:16:17.226999Z","packages":[{"ecosystem":"npm","name":"@nyariv/sandboxjs","purl":"pkg:npm/%40nyariv/sandboxjs","ranges":["<0.8.35"],"fixed":["0.8.35"]}]}],"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).
