CVE-2025-69981 — FUXA v1.2.7 contains an Unrestricted File Upload vulnerability in the `/api/upload` API endpoint

Critical CVSS 9.8

FUXA v1.2.7 contains an Unrestricted File Upload vulnerability in the `/api/upload` API endpoint. The endpoint lacks authentication mechanisms, allowing unauthenticated remote attackers to upload arbitrary files. This can be exploited to overwrite critical system files (such as the SQLite user database) to gain administrative access, or to upload malicious scripts to execute arbitrary code.

Matched remediation archetype

Path traversal, unsafe upload, and file handling

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Trace untrusted filenames, archive entries, URLs, and path segments into read, write, include, extraction, and upload operations.
  • Identify filesystem roots, mount permissions, symbolic-link behavior, archive handling, and whether uploaded content is web-accessible or executable.
  • Review canonicalization and containment checks across supported operating systems and storage backends.

Remediate safely

  • Generate server-side storage identifiers and resolve paths beneath a fixed root using filesystem-aware containment checks.
  • Reject absolute, parent-relative, alternate-separator, device, link, and archive entries that escape the intended root.
  • Store uploads outside executable or served paths, validate type and size, and use private atomic temporary files.
