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
In PHP versions 8.1.* before 8.1.30, 8.2.* before 8.2.24, 8.3.* before 8.3.12, erroneous parsing of multipart form data contained in an HTTP POST request could lead to legitimate data not being processed. This could lead to malicious attacker able to control part of the submitted data being able to exclude portion of other data, potentially leading to erroneous application behavior.

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.

Fixed in 8.1.308.2.248.3.12
Recommended fix High confidence

PHP 8.1.30, 8.2.24, or 8.3.12 (select based on your current major version branch)

  1. Check current PHP version by running 'php -v' or 'phpinfo()'
  2. Update your system's package repository to ensure you have access to the latest PHP packages
  3. Upgrade PHP to version 8.1.30, 8.2.24, or 8.3.12 depending on your current major version branch (e.g., 'apt-get update && apt-get install php8.3' or 'yum update php83' depending on your OS)
  4. Restart any web servers (Apache, Nginx) or PHP-FPM services to load the new PHP version
  5. Verify the upgrade was successful by running 'php -v' and confirming the version number matches the target fixed release
  6. Test that multipart form data processing works correctly in your applications
Caveat Minor version upgrades within the same PHP branch typically have minimal breaking changes; however, review the PHP release notes for any deprecated functions or behavior changes between your current version and the target upgrade version
