CVE-2026-48242 Open ISES CVE debrief

CVE-2026-48242 affects Open ISES Tickets before 3.44.2. The issue is hardcoded MySQL connection credentials in import_mdb.php, which are stored in source code committed to the public repository. That makes valid database configuration values visible to anyone who can read the code, creating a serious credential-exposure risk if those values are reused in deployed systems.

Who should care

Open ISES Tickets maintainers, operators running affected versions, and security teams responsible for code review, secret management, and database access control. Any deployment that may have reused the embedded MySQL settings should be treated as at risk.

Technical summary

The vulnerability is a hardcoded-credentials issue (CWE-798). According to the published advisory data, import_mdb.php contained embedded MySQL host, username, password, and database name values in the public repository. The fix is associated with release v3.44.2 and the referenced repository commit. Exposure of these values can enable unauthorized database access if the same credentials are used in production or if the configuration closely matches deployed environments.

Defensive priority

High. The CVSS score is 9.2 (Critical), and the primary concern is disclosure of working database credentials from source control. Even when no direct remote exploit path is involved, secret leakage can lead to serious downstream compromise.

Recommended defensive actions

  • Upgrade Open ISES Tickets to version 3.44.2 or later.
  • Rotate any MySQL credentials that may have been exposed in the repository.
  • Verify whether deployed environments reused the hardcoded connection values and replace them with unique secrets.
  • Audit the codebase and repository history for additional embedded secrets or configuration leaks.
  • Review database permissions and reduce them to the minimum required for application operation.
  • Check access logs and administrative records for unexpected use of the exposed database account(s).

Evidence notes

The NVD record and the linked VulnCheck advisory describe hardcoded MySQL credentials in import_mdb.php and tie the remediation to Open ISES Tickets v3.44.2. The referenced GitHub commit and release tag provide the strongest source-backed evidence for the affected code and the fixed version. NVD lists the vulnerability status as Deferred, but the disclosure content still supports a high-confidence defensive response.
