Technical details
A Regular Expression Denial of Service (ReDoS) vulnerability (CWE-1333) exists in the `sql_parse.py` component of Apache Superset. The `SQL_REGEX` used for parsing SQL statements contains overlapping disjunctions with a common outer quantifier, leading to exponential backtracking when processing certain patterns. An authenticated attacker can trigger this by submitting a query with a long sequence of backslashes or repeated patterns to endpoints like `/api/v1/chart/data`. The issue is fixed in version 6.0.0; workarounds include implementing WAF rules to block long backslash sequences in the `queries.extras.where` parameter and applying strict rate limiting.
