Route schema disclosure via static-map placeholder collision
Published Sep 8, 2026 · Updated Sep 9, 2026
Observable discrepancy in Maravel Framework before 10.73.1 allows remote attackers to disclose route parameter names via crafted requests. The route compiler mistakenly inserts raw dynamic-placeholder keys into its flat static-route map, so literal brace syntax bypasses dynamic capture and triggers an ArgumentCountError. No authentication is required; comparing resulting 500 responses with ordinary 404 responses reveals internal parameter names and controller schemas.
