CVE-2021-41652
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedInsecure permissions in the file database.sdb of BatFlat CMS v1.3.6 allows attackers to dump the entire database.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceBatFlat CMS v1.3.6 stores a SQLite database file (database.sdb) with insecure file permissions, making it readable by unauthorized users. Attackers can directly access and download this file to dump the entire database, including user credentials and application data.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify BatFlat CMS installation and versionCheck for BatFlat CMS files and look for a version indicator. Common locations include: a version file (version.php or similar), the admin dashboard, or footer of pages.Affected if The installed version is exactly 1.3.6
-
Locate the database.sdb fileSearch for the file named database.sdb in the BatFlat installation directory. Typical paths include: /inc/core/database/ or a /data/ directory within the web root.Affected if The database.sdb file exists in a location within or accessible from the web root
-
Check file system permissions on database.sdbRun: ls -la /path/to/database.sdb (on Linux/Unix) or check Properties > Security on Windows. Verify the file is not readable by 'others' or 'everyone'.Affected if The file permissions allow read access to unauthorized users (e.g., mode 644, 666, or ACLs granting Everyone/Users read)
-
Verify HTTP accessibility of database.sdbAttempt to access the database.sdb file via web browser: http://yourdomain.com/path/to/database.sdb. Also check if the directory containing it allows directory listing.Affected if The file can be downloaded directly via HTTP without authentication
You are affected if BatFlat 1.3.6 is installed and the database.sdb file is either readable by unauthorized local users or directly accessible via HTTP from the web.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataRestrict file permissions on database.sdb to prevent unauthorized read access, and ideally relocate the database file outside the webroot directory to prevent direct HTTP access.
