CVE-2026-39931: OpenEMR through 8.2.0 contains an authenticated SQL injection vulnerability in the backup configuration import feature that allows administrators with admin or super ACL privileges to execute arbitrary DDL and DML statements against the application database by uploading a crafted SQL file at the form_step=202 parameter in backup.php. Attackers can exploit the unfiltered shell_exec invocation of the mysql command-line client to extract credential hashes, modify access control tables, inject backdoor accounts, create persistent triggers or stored procedures, and write arbitrary files to the filesystem where MySQL FILE privileges and permissive secure_file_priv settings are configured.
The exploitability of CVE-2026-39931 depends on two key factors: attack complexity (the level of effort required to execute an exploit) and privileges required (the access level an attacker needs).
The exploitability of CVE-2026-39931 is influenced by multiple factors. Security teams should analyze system configurations and apply appropriate countermeasures to mitigate threats.
A lower complexity and fewer privilege requirements make exploitation easier. Security teams should evaluate these aspects to determine the urgency of mitigation strategies, such as patch management and access control policies.
Attack Complexity (AC) measures the difficulty in executing an exploit. A high AC means that specific conditions must be met, making an attack more challenging, while a low AC means the vulnerability can be exploited with minimal effort.
Privileges Required (PR) determine the level of system access necessary for an attack. Vulnerabilities requiring no privileges are more accessible to attackers, whereas high privilege requirements limit exploitation to authorized users with elevated access.
Above is the CVSS Sub-score Breakdown for CVE-2026-39931, illustrating how Base, Impact, and Exploitability factors combine to form the overall severity rating. A higher sub-score typically indicates a more severe or easier-to-exploit vulnerability.
Below is the Impact Analysis for CVE-2026-39931, showing how Confidentiality, Integrity, and Availability might be affected if the vulnerability is exploited. Higher values usually signal greater potential damage.
