Machine-written summary

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

PowSyBl Core's RegexCriterion class in powsybl-iidm-criteria (6.3.0 to before 6.7.2) and powsybl-contingency-api (5.0.0 to before 6.3.0) is vulnerable to polynomial ReDoS. An attacker who can supply the regular expression and influence network object identifiers can cause heavy CPU consumption during filtering. Upgrade powsybl-iidm-criteria to 6.7.2 or later and powsybl-contingency-api to 6.3.0 or later.
