The vulnerability stems from insufficient authorization checks, enabling code execution beyond the intended sandboxed boundaries. If exploited, an attacker could compromise the confidentiality, integrity, or availability of the affected system. The weakness aligns with improper access control and privilege escalation scenarios.

The vulnerability is not listed in CISA\u2019s KEV catalog.
