GHSA-rqpx-f6rc-7hm5: com.powsybl:powsybl-commons (CVE-2025-48058)

Package	Ecosystem	Affected	Fixed in
com.powsybl:powsybl-commons	Maven	<6.7.2	6.7.2

Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

PowSyBl Core's powsybl-commons package (Maven com.powsybl:powsybl-commons) is vulnerable in versions before 6.7.2 to a polynomial ReDoS in the DataSource listNames(String regex) method. An attacker must control both the regular expression passed to that method and the names of files or resources being matched, which can cause heavy CPU use and slow the server for other users. Upgrade to powsybl-commons 6.7.2 or later. Applications that call listNames directly with user-supplied patterns should avoid passing untrusted regex input.
