Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Packagist packages — download data is not available via public APIs for these ecosystems.

Description

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');

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for z-push/z-push-dev, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Fix

    Update z-push/z-push-dev to 2.7.6 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms CVE-2025-8264 is resolved across your whole dependency graph.

  3. Workarounds

    Until you can upgrade, make sure every query built from user input uses parameterised statements or a prepared-statement API rather than string concatenation, and reduce the database account's privileges so an injected query cannot read or alter data beyond what the feature needs.
