CVE-2026-31156 (GCVE-0-2026-31156)

Vulnerability from nvd – Published: 2026-05-13 00:00 – Updated: 2026-07-05 01:35

Summary

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 files.

Severity

6.5 (Medium)

CVE-2026-35063 (GCVE-0-2026-35063)

Vulnerability from nvd – Published: 2026-04-09 19:00 – Updated: 2026-04-10 18:04

Title

Missing Authorization in OpenPLC_V3

Summary

OpenPLC_V3 REST API endpoint checks for JWT presence but never verifies the caller's role. Any authenticated user with role=user can delete any other user, including administrators, by specifying their user ID or they can create new accounts with role=admin, escalating to full administrator access.

Severity

8.7 (High)

CVE-2026-31156 (GCVE-0-2026-31156)

Vulnerability from cvelistv5 – Published: 2026-05-13 00:00 – Updated: 2026-07-05 01:35

Summary

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 files.

CVE-2026-35063 (GCVE-0-2026-35063)

Vulnerability from cvelistv5 – Published: 2026-04-09 19:00 – Updated: 2026-04-10 18:04

Title

Missing Authorization in OpenPLC_V3

Summary

OpenPLC_V3 REST API endpoint checks for JWT presence but never verifies the caller's role. Any authenticated user with role=user can delete any other user, including administrators, by specifying their user ID or they can create new accounts with role=admin, escalating to full administrator access.

Severity

8.7 (High)
