Sogo · Sogo · CVE-2026-8851
**Name of the Vulnerable Software and Affected Versions**
SOGo version 5.12.7
**Description**
An issue in the Access Control List management functionality allows authenticated users to extract arbitrary data from the database. This is achieved by injecting SQL subqueries through the `uid` parameter of the "/addUserInAcls" endpoint. Attackers can use malicious SQL code to write extracted data into the `sogo acl` table and subsequently retrieve it via the "/acls" API, creating an out-of-band data exfiltration channel.
**Recommendations**
As a temporary workaround, restrict access to the "/addUserInAcls" endpoint or avoid using the `uid` parameter until a fix is available.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.
