| CVE | 概要 | ソース | CVSS 最大値 | EPSS（%） | 公開 | 更新 |
|---|---|---|---|---|---|---|
| CVE-2026-31156 | A path injection vulnerability exists in OpenPLC v3 (2c82b0e79c53f8c1f1458eee15fec173400d6e1a) as the binary program compiled from glue_generator.cpp does not perform any validation on the file path parameters passed via the command line. The user-controlled input parameters are directly passed to the underlying file operation functions (fopen/ifstream/ofstream) for file reading and writing. An attacker can exploit this vulnerability by constructing a malicious path to read arbitrary readable fi | [email protected] | 6.5 | 0.41% | 2026-05-13 | 2026-06-17 |
