What is CVE-2025-48059?

The PowSyBl framework, specifically within the RegexCriterion class, is susceptible to a regular expression denial of service (ReDoS) due to its handling of unvalidated user-supplied regular expressions. This vulnerability can lead to excessive CPU consumption when the regular expressions are evaluated, particularly during operations on large network models. Attackers could exploit this by repeatedly triggering recursive processing of filters, resulting in severe performance degradation. Users are advised to upgrade to the patched versions available in com.powsybl:powsybl-iidm-criteria 6.7.2 to mitigate this risk.

Human OS v1.0:
