CVE-2025-8264

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');

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:H)
Even with access, the exploit needs extra luck, timing, or a fussy environment to actually work.
Privileges required (PR:N)
No account or special rights needed—anonymous or random user is enough.
User interaction (UI:N)
Nobody has to click “OK” or open a trap file; it can work without a victim helping.
Scope (S:C)
Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:H)
Serious risk that confidential data gets exposed in a big way.
Integrity (I:H)
They could widely tamper with or forge data—trust in the data is badly hurt.
Availability (A:H)
Could take the service down hard or make it unusable for people who depend on it.
