SandboxJS has an execution-quota bypass (cross-sandbox currentTicks race) in SandboxJS timers

Summary Assumed repo path is /Users/zwique/Downloads/SandboxJS-0.8.34 no /Users/zwique/Downloads/SandboxJS found. 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...

CVE-2026-26954

SandboxJS is a JavaScript sandboxing library. Prior to 0.8.34, it is possible to obtain arrays containing Function, which allows escaping the sandbox. Given an array containing Function, and Object.fromEntries, it is possible to construct p: Function where p is any constructible property. This...

CVE-2026-26954

SandboxJS is a JavaScript sandboxing library. Before version 0.8.34, it can leak arrays containing Function, enabling sandbox escape when used with Object.fromEntries to construct {[p]: Function} for any constructible property. This leads to Sandbox Escape with potential RCE as described in multi...
