CVE-2026-15815

A flaw was found in Grafana. When extracting plugin archives, Grafana did not safely resolve symbolic links. A remote attacker could craft a malicious plugin archive with symbolic links to escape the plugin installation directory. This allows the attacker to write arbitrary files and execute malicious code with the privileges of the Grafana server process, leading to remote code execution.

8.8 (High)

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

Vulnerability from cvelistv5 – Published: 2026-09-17 20:47 – Updated: 2026-09-19 03:56

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.

A crafted plugin archive can chain relative symbolic link\nentries to escape the plugin installation directory, writing arbitrary files and an\nexecutable backend binary outside that directory. The dropped executable runs with the\nprivileges of the Grafana server process, resulting in remote code execution.\n\nPlugin archives are extracted before their signature is verified, so a valid plugin\nsignature does not prevent the write. An operator can therefore be affected by\ninstalling a plugin that appears legitimate, as well as by installing a plugin from an\narbitrary archive using grafana-cli, the GF_INSTALL_PLUGINS environment variable, or\npreinstall configuration.\n\nGrafana Enterprise is affected because it includes the same plugin extraction code as\nGrafana OSS."

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
