Detailsinfo A vulnerability, which was classified as problematic, has been found in nyariv SandboxJS up to 0.8.34. Affected by this issue is the function currentTicks.current of the component Timer Call Handler. The manipulation with an unknown input leads to a race condition vulnerability. Using CWE to declare the problem leads to CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. Impacted is availability. CVE summarizes: 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. The advisory is shared for download at github.com. This vulnerability is handled as CVE-2026-32723 since 03/13/2026. The exploitation is known to be easy. The attack needs to be approached locally. There are known technical details, but no exploit is available. Upgrading to version 0.8.35 eliminates this vulnerability. Applying the patch cc8f20b4928afed5478d5ad3d1737ef2dcfaac29 is able to eliminate this problem. The bugfix is ready for download at github.com.
