Versions of the package z-push/z-push-dev before 2.7.6 are vulnerable to SQL Injection due to unparameterized queries in the IMAP backend. An attacker can inject malicious commands by manipulating the username field in basic authentication. This allows the attacker to access and potentially modify or delete sensitive data from a linked third-party database. **Note:** This vulnerability affects Z-Push installations that utilize the IMAP backend and have the IMAP_FROM_SQL_QUERY option configured. Mitigation Change configuration to use the default or LDAP in backend/imap/config.php php define('IMAP_DEFAULTFROM', ''); or php define('IMAP_DEFAULTFROM', 'ldap');

Security readout for executives and security teams

Plain-English summary

A remote, unauthenticated attacker may abuse the login username to compromise a database connected to certain Z-Push installations. Successful exploitation could alter or delete sensitive data. Risk is limited to versions before 2.7.6 using the IMAP backend with SQL-based sender identity configuration.

Executive priority

Treat affected installations as an urgent remediation item because database integrity and connected systems may be at risk. Prioritize externally reachable deployments and those linked to sensitive databases. Validate configuration first, since unaffected backends or non-SQL identity settings materially reduce exposure.

Technical view

CVE-2025-8264 is a CWE-89 SQL injection caused by unparameterized IMAP-backend queries. Attacker-controlled basic-authentication usernames can reach the query when IMAP_FROM_SQL_QUERY is configured. The supplied CVSS 4.0 score is 9.1, reflecting potentially high integrity and downstream confidentiality, integrity, and availability impact.

Likely exposure

Exposure requires all identified conditions: z-push/z-push-dev before 2.7.6, the IMAP backend, and IMAP_FROM_SQL_QUERY configuration. Installations using the default sender configuration or LDAP are not described as affected. Internet-accessible synchronization endpoints would present greater practical exposure.

Exploitation context

The bundle identifies a remote attack path requiring no privileges or user interaction, but records CISA KEV status as false. It does not establish active exploitation in the wild. Public vulnerability research and a corrective code change are referenced, so defenders should not treat the issue as merely theoretical.

Researcher notes

The vulnerable path is reported in the IMAP identity lookup and depends on attacker-controlled basic-authentication usernames reaching an unparameterized query. Scope should be confirmed against deployed code and configuration. The bundle does not quantify attack prevalence or prove compromise; incident conclusions require local log and database evidence.

Mitigation direction

  • Upgrade z-push/z-push-dev to version 2.7.6 or later.
  • If upgrading is delayed, stop using IMAP_FROM_SQL_QUERY.
  • Set IMAP_DEFAULTFROM to the default empty value or LDAP, as appropriate.
  • Check current Z-Push vendor guidance before finalizing remediation.

Validation and detection

  • Inventory Z-Push versions and identify installations earlier than 2.7.6.
  • Confirm whether each installation actively uses the IMAP backend.
  • Inspect backend/imap/config.php for SQL-based sender identity configuration.
  • Review authentication and linked-database logs for suspicious username-related query activity.
  • After remediation, verify configuration and normal synchronization behavior.
