Zimbra has released updates for its Collaboration software to fix critical security flaws that could lead to information disclosure if exploited. CVE-2025-25064 is a critical vulnerability with a CVSS score of 9.8. It is an SQL injection issue in the ZimbraSync Service SOAP endpoint, affecting versions before 10.0.12 and 10.1.4.
Stemming from a lack of adequate sanitization of a user-supplied parameter, the shortcoming could be weaponized by authenticated attackers to inject arbitrary SQL queries that could retrieve email metadata by “manipulating a specific parameter in the request.”
