Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 26.1th percentile by exploit likelihood (below the median); it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
The strongest mitigations our analysis identified are NIST 800-53 SI-10 (Information Input Validation) and AC-6 (Least Privilege).
Deeper analysis
CVE-2026-1546 is a SQL injection vulnerability (CWE-74, CWE-89) affecting jishenghua jshERP versions up to 3.6. The issue resides in the getBillItemByParam function within the file /jshERP-boot/depotItem/importItemExcel of the com.jsh.erp.datasource.mappers.DepotItemMapperEx component. It is triggered by manipulation of the barCodes argument.
A remote attacker with low privileges (PR:L) can exploit this vulnerability with low attack complexity (AC:L) and no user interaction (UI:N). Successful exploitation enables limited impacts on confidentiality, integrity, and availability (C:L/I:L/A:L), as reflected in its CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L).

Mitigating Controls (NIST 800-53 r5) AI
Directly requires validation and sanitization of the barCodes argument before it reaches getBillItemByParam, blocking the SQL injection payload.
Enables monitoring of database query patterns and anomalies originating from the importItemExcel endpoint to identify successful or attempted injection.
Restricts the database privileges of the application account used by DepotItemMapperEx so that even a successful barCodes injection yields only limited impact.
