CVE-2026-15815 (GCVE-0-2026-15815)

Title
CVE-2026-15815 CVE Record
Summary
Grafana OSS and Grafana Enterprise did not safely resolve symbolic links when
extracting plugin archives. A crafted plugin archive can chain relative symbolic link
entries to escape the plugin installation directory, writing arbitrary files and an
executable backend binary outside that directory. The dropped executable runs with the
privileges of the Grafana server process, resulting in remote code execution.
Plugin archives are extracted before their signature is verified, so a valid plugin
signature does not prevent the write. An operator can therefore be affected by
installing a plugin that appears legitimate, as well as by installing a plugin from an
arbitrary archive using grafana-cli, the GF_INSTALL_PLUGINS environment variable, or
preinstall configuration.
Grafana Enterprise is affected because it includes the same plugin extraction code as
Grafana OSS.

Glarysoft Glary Utilities Link Following Local Privilege Escalation Vulnerability
Summary
Glarysoft Glary Utilities Link Following Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Glarysoft Glary Utilities. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability.
The specific flaw exists within the Disk Clean functionality. By creating a junction, an attacker can abuse the service to delete arbitrary files. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-27004.

Mitigation MIT-48.1
Architecture and Design
Strategy: Separation of Privilege
- Follow the principle of least privilege when assigning access rights to entities in a software system.
- Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
CAPEC-132: Symlink Attack
An adversary positions a symbolic link in such a manner that the targeted user or application accesses the link's endpoint, assuming that it is accessing a file with the link's name.
CAPEC-17: Using Malicious Files
An attack of this type exploits a system's configuration that allows an adversary to either directly access an executable file, for example through shell access; or in a possible worst case allows an adversary to upload a file and then execute it. Web servers, ftp servers, and message oriented middleware systems which have many integration points are particularly vulnerable, because both the programmers and the administrators must be in synch regarding the interfaces and the correct privileges for each interface.
CAPEC-35: Leverage Executable Code in Non-Executable Files
An attack of this type exploits a system's trust in configuration and resource files. When the executable loads the resource (such as an image file or configuration file) the attacker has modified the file to either execute malicious code directly or manipulate the target process (e.g. application server) to execute based on the malicious configuration parameters. Since systems are increasingly interrelated mashing up resources from local and remote sources the possibility of this attack occurring is high.
CAPEC-76: Manipulating Web Input to File System Calls
An attacker manipulates inputs to the target software which the target software passes to file system calls in the OS. The goal is to gain access to, and perhaps modify, areas of the file system that the target software did not intend to be accessible.
