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 · unedited
There is an upload sql injection vulnerability in the background of taocms 3.0.2 in parameter id:action=cms&ctrl=update&id=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
How this class of weakness works · CWE-89

User input is woven into a database query, letting an attacker rewrite the query's logic. From there they can read, alter, or destroy data — frequently the entire database. The reliable fix is parameterised queries (prepared statements), so input is always treated as data and never as SQL.

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.

Recommended fix Moderate confidence

Taocms version newer than 3.0.2 (check GitHub releases for post-December 2021 releases)

  1. 1. Navigate to the official Taocms repository on GitHub (github.com/taogogo/taocms)
  2. 2. Check the releases or tags section for versions newer than 3.0.2
  3. 3. Download the latest stable release (verify release date is after December 2021 when CVE-2021-45014 was disclosed)
  4. 4. Backup your current database and website files before upgrading
  5. 5. Replace the existing taocms installation files with the new version
  6. 6. Restore your configuration files (database connection settings) to the new installation
  7. 7. Test the admin panel functionality, particularly the CMS update function at action=cms&ctrl=update
  8. 8. Verify the SQL injection vulnerability is no longer present by testing the id parameter with typical SQL injection payloads (e.g., id=26' OR '1'='1)
Caveat Minor version upgrades typically maintain backwards compatibility, but always test on a staging environment first

Generated from the published advisory — verify against the referenced sources before acting.

No vendor fix exists Taocms has not published a patch for this.

There is no version to upgrade to and no patch to apply. Every affected install stays exposed until the vendor ships a fix — or somebody else builds one.
