When configured with a file-system database backend, the application lacks input validation on the request-controlled project query parameter. An authenticated attacker with low privileges can supply directory traversal sequences to read arbitrary JSON or YAML files on the host file system.\n\n## TL;DR\nUnvalidated project query parameters in Perses allow authenticated path traversal and arbitrary JSON/YAML file reading when using the file-system database.\n\n## Technical Details\n\n- **CWE ID**: CWE-22\n- **Attack Vector**: Network\n- **CVSS v4.0 Score**: 7.1\n- **Privileges Required**: Low\n- **Exploit Status**: None\n- **CISA KEV Status**: Not Listed\n\n## Affected Systems\n\n- Perses (observability dashboard and visualization project)\n- **Perses**: < 0.54.0-rc.0 (Fixed in: `0.54.0-rc.0`)\n\n## Mitigation\n\n- Upgrade Perses to version 0.54.0-rc.0 or later to enforce strict input validation.\n- Deploy Web Application Firewall (WAF) rules to detect and block path traversal sequences in query parameters.\n- Apply the principle of least privilege to the host process execution environment.\n\n**Remediation Steps:**\n1. Identify all Perses deployments running versions prior to 0.54.0-rc.0.\n2. Back up the local database files located in the storage directory.\n3. Update the Perses container image or binary to version 0.54.0-rc.0 or a later stable release.\n4. Verify that requests with traversal parameters return a 400 Bad Request error.\n5. Ensure the Perses service runs under a non-root system user account.\n\n## References\n\n- [GitHub Security Advisory GHSA-vr5f-w35q-98jp](https://github.com/perses/perses/security/advisories/GHSA-vr5f-w35q-98jp)\n- [NVD Vulnerability Entry](https://nvd.nist.gov/vuln/detail/CVE-2026-63445)\n- [CVE.org Record](https://www.cve.org/CVERecord?id=CVE-2026-63445)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-63445) - Automated Vulnerability Intelligence*", "creation_timestamp": "2026-09-19T04:31:13.997453Z"}]}
