{"id":"CVE-2025-47771","state":"PUBLISHED","title":"PowSyBl Core allows deserialization of untrusted SparseMatrix data","description":"PowSyBl (Power System Blocks) is a framework to build power system oriented software. In versions 6.3.0 to 6.7.1, there is a deserialization issue in the read method of the SparseMatrix class that can lead to a wide range of privilege escalations depending on the circumstances. This method takes in an InputStream and returns a SparseMatrix object. This issue has been patched in com.powsybl:powsybl-math: 6.7.2. A workaround for this issue involves not using SparseMatrix deserialization (SparseMatrix.read(...) methods).","publishedAt":"2025-06-19T23:41:41.357Z","updatedAt":"2025-06-20T15:55:29.328Z","severity":{"score":8.1,"label":"High","version":"4.0","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U","source":"GitHub_M"},"assigner":"GitHub_M","products":["powsybl powsybl-core"],"affected":[{"vendor":"powsybl","product":"powsybl-core","versions":[{"version":">= 6.3.0, < 6.7.2","status":"affected"}]}],"references":["https://github.com/powsybl/powsybl-core/security/advisories/GHSA-f5cx-h789-j959","https://github.com/powsybl/powsybl-core/commit/8ed16ce41683c4aef5f6aa1dd5ae8642aa5ed2bd","https://github.com/powsybl/powsybl-core/releases/tag/v6.7.2"],"weaknesses":["CWE-502"],"ingestedAt":"2026-10-29T20:09:23.771Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2025/47xxx/CVE-2025-47771.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2025-47771","state":"PUBLISHED","datePublished":"2025-06-19T23:41:41.357Z","dateUpdated":"2025-06-20T15:55:29.328Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2025-05-09T19:49:35.619Z"},"containers":{"cna":{"title":"PowSyBl Core allows deserialization of untrusted SparseMatrix data","descriptions":[{"lang":"en","value":"PowSyBl (Power System Blocks) is a framework to build power system oriented software.
