HCL Sametime for iOS is impacted by a sensitive information disclosure.  Hostnames information is written in application logs and certain URLs.

CVE-2026-21786 identifies a vulnerability in HCLSoftware Sametime for iOS, specifically versions earlier than 12.0.26, where sensitive information such as hostnames and certain URLs are improperly recorded in application log files. This vulnerability is classified under CWE-532, which pertains to the insertion of sensitive information into log files, potentially exposing confidential data to unauthorized users who have access to these logs. The vulnerability has a CVSS 3.1 base score of 3.3, indicating low severity. The vector metrics show that exploitation requires local access (AV:L), low attack complexity (AC:L), and low privileges (PR:L), with no user interaction (UI:N) needed. The impact is limited to confidentiality (C:L), with no effect on integrity or availability. The flaw arises because the application logs sensitive data such as hostnames and URLs, which could reveal internal network structure or endpoints if logs are accessed by attackers or unauthorized personnel. Although no exploits are known in the wild, the presence of sensitive data in logs can facilitate further attacks, including reconnaissance or targeted exploitation. The vulnerability was published on March 5, 2026, and no official patches or mitigation links were provided at the time, but upgrading to version 12.0.26 or later is recommended. This issue highlights the importance of secure logging practices, especially in communication applications like Sametime that handle sensitive organizational data.
