CyberRota Analysis
AI-GeneratedThe vulnerability allows attackers to bypass length and match constraints by submitting case-insensitive string values that, when folded, violate the specified rules. This can lead to improper data storage and potential application logic flaws. Developers using affected versions of the Ash framework (1.29.0-rc0 through 3.32.2) should prioritize addressing this issue to ensure data integrity and compliance with validation requirements.

Original NVD Description
Incorrect Behavior Order: Validate Before Canonicalize vulnerability in ash-project ash lets an attacker store a case-insensitive string value that violates its length or match constraints. Ash.Type.CiString.apply_constraints/2 (lib/ash/type/ci_string.ex) validated the max_length, min_length, and match constraints against the value as submitted, while the type case-folds the string (per its casing) for storage and comparison. Because validation ran before folding, an attacker can submit a value whose folded form breaks a constraint but whose original form passes: for example, against a match pattern requiring uppercase, an uppercase value that is stored lowercased persists a value the pattern rejects. The fix case-folds the value at the start of apply_constraints/2, so the constraints are checked against the form that is actually stored. This issue affects ash: from 1.29.0-rc0 before 3.32.2.
