CVE-2025-71316
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 · uneditedSQLite 'sqldiff.exe' does not securely handle the way the Microsoft Windows C runtime converts Unicode characters to ANSI codepages. An attacker could use the '-L' option to load an arbitrary DLL with a crafted command line argument string that results in command line file arguments being misinterpreted as command line options. Fixed on or around 2025-12-26.
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 confidenceSQLite's sqldiff.exe utility contains a DLL hijacking vulnerability stemming from how the Windows C runtime handles Unicode-to-ANSI codepage conversion. Attackers can exploit the `-L` option with a crafted command line to load arbitrary DLLs by tricking file arguments into being misinterpreted as command-line options, achieving remote code execution.

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.
-
Locate sqldiff.exe on the systemSearch for sqldiff.exe in common directories such as C:\Program Files\SQLite, C:\Program Files (x86)\SQLite, or directories in the system PATH. Use 'where sqldiff.exe' from command prompt or Get-ChildItem -Recurse -Filter sqldiff.exe from PowerShell.Affected if sqldiff.exe is present on the system and was obtained from an unpatched SQLite build dated before 2025-12-26
-
Determine sqldiff.exe versionRun 'sqldiff.exe --version' or right-click the file, select Properties, and check the Version tab. Compare the build date and version number against the fix released on or around 2025-12-26.Affected if The version or build date is older than the patched release from late December 2025
-
Identify usage of the -L optionSearch scripts, scheduled tasks, and command history for occurrences of 'sqldiff' combined with '-L' flag. Use 'findstr /s /i /m "sqldiff.*-L" *.bat *.ps1 *.cmd' in relevant directories, or review application logs and process monitoring records.Affected if The -L option is used with sqldiff.exe, particularly with arguments that could originate from untrusted sources
-
Audit command line arguments passed to sqldiffReview any automation or application code that invokes sqldiff.exe. Examine how arguments are constructed, especially whether user input flows into the command line without sanitization.Affected if User-supplied or unvalidated input is directly passed as arguments to sqldiff.exe, especially near the -L flag
A user is affected if sqldiff.exe from an unpatched build (pre-2025-12-26) is present AND the -L option is being used with arguments that could be crafted or supplied by untrusted sources, enabling potential arbitrary DLL loading.

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 dataUpdate sqldiff.exe to the version released on or after 2025-12-26 that includes the security fix. Avoid running sqldiff.exe with untrusted input or in untrusted directories where malicious DLLs could be loaded.
