Summary
MantisBT: SQL Injection via history_order Configuration Value
MantisBT 2.28.3 and earlier versions contains a SQL injection vulnerability in core/history_api.php. The history_order configuration value is concatenated directly into a SQL ORDER BY clause without any sanitisation, parameterization, or validation against a whitelist.
An administrator can set this configuration value via the web UI (adm_config_set.php) or the REST API (PATCH /api/rest/config). The injected SQL then executes whenever any user views a bug with history entries.
Workarounds
Is there a way for users to fix or remediate the vulnerability without upgrading?

Impact
- Sensitive data extraction from the entire bugtracker database including user credentials (cookie_string, password hashes), API tokens, and private issue data
- With MySQL FILE privilege: full RCE via INTO OUTFILE writing a PHP webshell to the web root
- The admin plants the payload once; any authenticated user viewing a bug with history triggers the injection
Untrusted input alters a database query, allowing the attacker to read or modify data the query was not intended to access. Typical impact: data disclosure or modification.

Kodem intelligence
Severity tells you how bad this could be in the worst case. It does not tell you whether you are exposed. Exploitability and impact are functions of runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A vulnerable package can sit in your dependency tree and never run.
Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter. Kodem's runtime-powered SCA identifies whether this CVE is reachable in your applications.

Frequently Asked Questions
- What is CVE-2026-47142? CVE-2026-47142 is a high-severity SQL injection vulnerability in mantisbt/mantisbt (composer), affecting versions <= 2.28.3. It is fixed in 2.28.4. Untrusted input alters a database query, allowing the attacker to read or modify data the query was not intended to access.
- Which versions of mantisbt/mantisbt are affected by CVE-2026-47142? mantisbt/mantisbt (composer) versions <= 2.28.3 is affected.
- Is there a fix for CVE-2026-47142? Yes. CVE-2026-47142 is fixed in 2.28.4. Upgrade to this version or later.
- Is CVE-2026-47142 exploitable, and should I be worried? Whether CVE-2026-47142 is exploitable in your environment depends on whether the vulnerable code is present and reachable. A CVSS score is a worst-case rating; it does not account for your specific deployment, configuration, or usage patterns. Kodem, an Intelligent Application Security platform, uses runtime intelligence to show which vulnerabilities actually execute in production, so you can focus on the ones that represent real risk.

- What actually determines whether CVE-2026-47142 is exploitable, and how bad it is? Exploitability and impact are not fixed properties of a CVE. They depend on runtime truth: whether the vulnerable code is present, reachable, and actually executes in your application. A high CVSS score on a dependency that never runs is not the same as real risk. Kodem, an Intelligent Application Security platform, uses runtime intelligence to reveal which vulnerabilities actually execute in production, so teams prioritize the ones that genuinely matter.
- How do I fix CVE-2026-47142? Upgrade
