Recurring patterns
The bug types that recur here, drawn from past fixes, not open vulnerabilities.
Auth Bypass: Logical flaws in session key validation and missing default spend limits allowed transactions to bypass targets, selectors, and spending constraints. Developers must ensure default constraints (e.g., zero spend limit) are strictly applied and validations are not logically inverted.
Auth Bypass: Incomplete signature verification without wrapper structures permitted signature exploitation. Implementing strict wrapping (e.g., ERC-1271) and key authorization checks is essential.
SSR Bypass: The use of suffix-based matching (e.g., with endsWith) instead of exact host validation allowed attackers to bypass domain whitelisting controls.
