Unauthenticated stored XSS via insufficient output escaping
Published Feb 3, 2025 · Updated Apr 28, 2026
Stored XSS in WP BASE Booking 5.0.0 and earlier allows remote attackers to inject scripts through unauthenticated booking input. Published records do not identify the affected booking field or rendering function; they state only that input is stored without sufficient sanitization and later output without escaping. No account is required to plant the payload, but script execution requires another user to open an injected page, enabling actions in that user's browser context.
