CVE-2026-93953: Software Security Vulnerability Vulnerability
HIGHCVE-2026-93953 is a HIGH (CVSS 8.0) security vulnerability vulnerability (CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection')) affecting Software libraries in the Maven ecosystem. The weakness occurs when the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data.. Remediation is available in the latest vendor maintenance releases.

Security Impact
CVSS: 8.0
The security impact metrics below are parsed directly from the CVSS v3.1 vector string (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:H).
How to Fix CVE-2026-93953
To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.
Run the following command in your project directory to verify that all resolved dependencies use the patched release:
mvn dependency:treeHow to Check if You Are Affected
To determine whether your Java application is affected by CVE-2026-93953, inspect your build dependencies using the Maven Dependency Plugin:
mvn dependency:treeAnalyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.
Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.
Technical Details
Vulnerability Mechanism & Technical Analysis
This vulnerability is classified under CWE-89: Improper Neutralization of Special Elements used in an SQL Command ('SQL Injection'), where the product constructs all or part of an sql command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended sql command when it is sent to a downstream component. without sufficient removal or quoting of sql syntax in user-controllable inputs, the generated sql query can cause those inputs to be interpreted as sql instead of ordinary user data. In Software, software state validation or input boundaries are circumvented during processing.

"details" : "The Backuply – Backup, Restore, Migrate and Clone plugin for WordPress is vulnerable to SQL Injection via the Biographical Info field (second-order, via restore) in all versions up to, and including, 1.5.8 due to insufficient escaping on the user supplied parameter and the lack of sufficient preparation on an existing SQL query. Backuply exports the Biographical Info value verbatim inside an INSERT statement written to the backup's SQL dump (wp_usermeta). When an Administrator later restores such a backup, the crafted payload breaks out of that INSERT statement and appends attacker-controlled SQL that executes with full database privileges. This makes it possible for authenticated attackers, with subscriber-level access and above, to write arbitrary data to the database — in particular to update the default_role option in wp_options to administrator (and enable open user registration) — so that a subsequently registered account is automatically granted the Administrator role, resulting in privilege escalation and full site takeover. Because the injection executes inside an INSERT during restore with no response returned to the attacker, the primitive is used to modify database records rather than to read existing data directly.",
