Please do not open a public issue for security problems. Instead, use one of the private channels:

• GitHub: report a vulnerability via private vulnerability reporting — preferred.
• Email: edloidas@gmail.com with [roll-parser security] in the subject if you cannot use GitHub.

Include the notation or input that triggers the problem, the observed behavior, and the impact you believe it has. You should receive an initial response within a week.

roll-parser evaluates untrusted dice notation by design, so crashes, hangs, unbounded resource consumption, or any input that escapes the typed RollParserError contract are in scope — see the Safety limits the library promises to enforce. SeededRNG is documented as not cryptographically secure; predictability of its sequences is not a vulnerability.
