Vulnerability details
The vulnerability allows a remote attacker to bypass script-content preflight validation.
The vulnerability exists due to incomplete list of disallowed inputs in exec script preflight validation when processing complex interpreter invocations such as pipes or other non-simple command forms. A remote attacker can supply an attacker-controlled command shape to bypass script-content preflight validation.
This issue weakens a defense-in-depth guard that was intended to block unsafe script content before execution.
