CVE-2026-44522: CWE-20: Improper Input Validation in enchant97 note-mark
Note Mark versions from 0. 13. 0 up to but not including 0. 19. 4 allow authenticated users to upload assets with filenames that are not properly sanitized. The filename is stored directly in the database and later used in file path construction during data export without validation. This enables directory traversal attacks during export, allowing files to be written outside the intended directory. The vulnerability is fixed in version 0. 19. 4.
AI Analysis
Technical Summary
The Note Mark application (versions >= 0.13.0 and < 0.19.4) suffers from improper input validation (CWE-20) and directory traversal (CWE-22) in its asset upload feature. Authenticated users can specify asset filenames via the X-Name HTTP header without sanitization. These filenames are stored as-is in the database and later used in filepath.Join() calls during export commands, which resolve directory traversal sequences like '../'. This leads to arbitrary file write outside the export directory during the export process. The issue is resolved in version 0.19.4.
Potential Impact
An attacker with authenticated access can craft asset filenames containing directory traversal sequences that cause the export process to write files to arbitrary locations on the filesystem. This can lead to unauthorized file creation or overwriting, potentially compromising system integrity or confidentiality. The vulnerability has a high CVSS 4.0 score of 8.6, indicating significant impact if exploited.
Mitigation Recommendations
This vulnerability is fixed in Note Mark version 0.19.4. Users should upgrade to version 0.19.4 or later to remediate this issue. There is no official vendor advisory provided here, but the fix is confirmed in the version history. Until upgraded, restrict authenticated user privileges and avoid running export commands on untrusted data.
