CVE-2026-75855: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in ArcadeData arcadedb
ArcadeDB versions prior to 26.8.1 contain a path traversal vulnerability in the POST /api/v1/server endpoint. Authenticated root users can exploit this flaw by supplying crafted database names with '../' sequences, enabling them to create or delete files outside the intended database directory. This allows arbitrary file write and deletion on the filesystem accessible to the server process.
AI Analysis
Technical Summary
CVE-2026-75855 is a path traversal vulnerability in ArcadeDB before version 26.8.1. The issue arises because the database names in the create and drop database commands of the POST /api/v1/server endpoint are not properly sanitized. Authenticated root users can exploit this by including '../' sequences in database names, allowing them to write files or recursively delete directories outside the configured database directory.
Potential Impact
An attacker with authenticated root privileges can write arbitrary files or delete arbitrary files and directories on the server filesystem accessible to the ArcadeDB process. This can lead to data loss, service disruption, or potential further compromise depending on the server environment and permissions.
Mitigation Recommendations
Upgrade ArcadeDB to version 26.8.1 or later where this vulnerability is fixed. No other mitigations are indicated. Patch status is confirmed fixed in 26.8.1.
