CPU exhaustion via DataSource regex backtracking
Published Jun 20, 2025 · Updated Jun 20, 2025
ReDoS in PowSyBl Core before 6.7.2 allows remote attackers to exhaust CPU resources through crafted DataSource inputs. The listNames(String regex) method compiles an unvalidated caller-supplied pattern and matches it against file-like resource names, allowing extensive backtracking on near-matches. Exploitation requires control of both the regex and the matched filenames through a direct ReadOnlyDataSource call; PowSyBl's internal calls use hardcoded patterns.

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.
