CPU exhaustion via RegexCriterion backtracking
Published Jun 20, 2025 · Updated Jun 20, 2025
Polynomial ReDoS in PowSyBl Core 5.0.0 through 6.7.1 allows remote attackers to exhaust CPU via crafted regular expressions. RegexCriterion compiles an unvalidated pattern with java.util.regex.Pattern and applies find() to an Identifiable object's attacker-influenced ID, enabling polynomial backtracking. Exploitation requires control of the criterion expression and influence over network identifiers; repeated or recursive filter() calls cause sustained processing delays without reported data access or modification.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
- Affected versionversion=>= 5.0.0, < 6.3.0
- Affected versionversion=>= 6.3.0, < 6.7.2
