CVE-2025-65741 identifies a dylib injection vulnerability in Sublime Text 3 Build 3208 and earlier versions running on macOS. Dynamic library injection is a technique where an attacker forces an application to load a malicious dynamic library (.dylib) into its process space, enabling arbitrary code execution with the application's privileges. In this case, an attacker who can compile and place a malicious .dylib file on the victim's system can cause Sublime Text to load this library, thereby executing attacker-controlled code. This attack vector typically requires local access or the ability to write files to locations where Sublime Text loads libraries from. The vulnerability does not require user interaction beyond launching the application, making it stealthy once the malicious dylib is in place. The lack of a CVSS score indicates the vulnerability is newly published and not yet fully assessed. No known exploits have been reported in the wild, but the potential impact is significant due to the ability to execute arbitrary code. This could lead to data theft, corruption, or further system compromise. The vulnerability affects macOS users of Sublime Text 3 Build 3208 or earlier, which is a popular cross-platform text editor widely used by developers and IT professionals. The absence of patch links suggests that a fix may not yet be publicly available, emphasizing the need for interim mitigations. The attack surface is limited to macOS systems where Sublime Text is installed and where an attacker can place malicious dylibs. However, given Sublime Text's popularity in software development environments, the risk to organizations relying on macOS workstations is non-trivial.

For European organizations, this vulnerability poses a risk primarily to macOS endpoints running Sublime Text 3 Build 3208 or earlier. Successful exploitation could lead to arbitrary code execution, allowing attackers to compromise the confidentiality and integrity of source code, sensitive documents, and credentials stored or accessed via Sublime Text. It could also impact availability if the injected code disrupts application or system stability. Organizations in software development, creative industries, and IT services that rely on Sublime Text on macOS are particularly at risk. The vulnerability could be leveraged for lateral movement or persistence within corporate networks if attackers gain initial local access. Given the lack of known exploits in the wild, the immediate threat level is moderate, but the potential for damage is high if exploited. The impact is compounded in environments where endpoint security controls are weak or where users have elevated privileges. Additionally, the vulnerability could be used as part of targeted attacks against high-value individuals or teams using macOS for development or content creation.

1. Upgrade Sublime Text to the latest version once a patch addressing CVE-2025-65741 is released. Monitor official Sublime Text channels for updates. 2. Restrict write permissions on directories and paths where Sublime Text loads dynamic libraries to prevent unauthorized dylib placement. 3. Implement application whitelisting or code integrity policies on macOS endpoints to block execution of unauthorized dylibs. 4. Conduct regular endpoint scans for suspicious or unexpected dylib files in Sublime Text directories. 5. Educate users about the risks of running untrusted code and the importance of maintaining updated software. 6. Employ endpoint detection and response (EDR) solutions capable of detecting unusual library injection or code execution behaviors. 7. Limit local user privileges to reduce the risk of unauthorized file placement. 8. Monitor logs for anomalies related to Sublime Text process behavior or dylib loading events. 9. Consider network segmentation to isolate macOS development workstations from sensitive production environments. 10. Prepare incident response plans to quickly address potential exploitation scenarios involving this vulnerability.
