{"id":"CVE-2026-32723","summary":"SandboxJS timers have an execution-quota bypass (cross-sandbox currentTicks race)","details":"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.","aliases":["GHSA-7p5m-xrh7-769r"],"modified":"2026-07-08T07:32:32.189770025Z","published":"2026-03-18T21:27:35.349Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-362"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32723.json","unresolved_ranges":[{"extracted_events":[{"fixed":"0.8.35"}],"source":"AFFECTED_FIELD"}]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/32xxx/CVE-2026-32723.json"},{"type":"ADVISORY","url":"https://github.com/nyariv/SandboxJS/security/advisories/GHSA-7p5m-xrh7-769r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-32723"},{"type":"FIX","url":"https://github.com/nyariv/SandboxJS/commit/cc8f20b4928afed5478d5ad3d1737ef2dcfaac29"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/nyariv/sandboxjs","events":[{"introduced":"0"},{"fixed":"cc8f20b4928afed5478d5ad3d1737ef2dcfaac29"}],"database_specific":{"source":"REFERENCES"}}],"versions":["v0.8.34","v0.8.33","0.8.32","0.8.31","0.8.30","0.8.29","0.8.28","0.8.24-2","0.8.24-1","0.8.24","0.8.23.3","0.8.23-1","0.8.23.2","0.8.23","0.8.22","0.8.21","0.8.20","0.8.19","0.8.18","0.8.17","0.8.16","0.8.15.1","0.8.15","0.8.14","0.8.12","0.8.11","0.8.10","0.8.9","0.8.8","0.8.7","0.8.6","0.8.5","0.8.4","0.8.3","0.8.2","0.8.0","0.7.1","0.7.0","0.6.2","0.6.1","0.6.0","0.5.3","0.5.2","0.5.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-32723.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V4","score":"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"}]}
