CVE-2026-25641
CriticalSummary
SandboxJS to biblioteka do sandboxingu JavaScript. W wersjach przed 0.8.29 występuje podatność na ucieczkę z sandboxa spowodowana niezgodnością między kluczem używanym do walidacji a kluczem używanym do dostępu do właściwości.
Risk Assessment
Atakujący mogą wykorzystać tę podatność do wstrzykiwania złośliwych obiektów, co może prowadzić do nieautoryzowanego dostępu do danych lub wykonania niebezpiecznego kodu. Organizacje powinny być świadome ryzyka związanego z używaniem nieaktualnych wersji tej biblioteki.
Recommendation
Zaleca się aktualizację biblioteki SandboxJS do wersji 0.8.29 lub nowszej, aby usunąć tę podatność. Dodatkowo, warto przeprowadzić audyt kodu w celu identyfikacji potencjalnych zagrożeń związanych z używaniem tej biblioteki.

Original NVD description (English source)
SandboxJS is a JavaScript sandboxing library. Prior to 0.8.29, there is a sandbox escape vulnerability due to a mismatch between the key on which the validation is performed and the key used for accessing properties. Even though the key used in property accesses is annotated as string, this is never enforced. So, attackers can pass malicious objects that coerce to different string values when used, e.g., one for the time the key is sanitized using hasOwnProperty(key) and a different one for when the key is used for the actual property access. This vulnerability is fixed in 0.8.29.
