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 confidenceA code injection vulnerability exists in Flute CMS 0.2.2.4-alpha's ContentParser.php file within the replaceContent function used by the Notification Handler. The vulnerability allows remote attackers to inject malicious code through manipulated content input, likely due to insufficient input sanitization in the content parsing logic.

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.
-
Verify Flute CMS versionLocate the version file or metadata in your Flute CMS installation (typically in composer.json, package.json, or a version.php file) and compare the installed version to 0.2.2.4-alphaAffected if The installed version is exactly 0.2.2.4-alpha or matches the affected version range = 0.2.2.4
-
Locate ContentParser.phpSearch for the file ContentParser.php in your Flute CMS installation directory, typically under src/ or similar source directoriesAffected if The file ContentParser.php exists in the installation and contains a function named replaceContent
-
Verify Notification Handler is activeCheck your Flute CMS configuration or module list to determine if the Notification Handler component is enabled or loadedAffected if The Notification Handler module/component is enabled and uses the ContentParser for processing content
-
Inspect replaceContent function for input handlingOpen ContentParser.php and locate the replaceContent function, then examine how it handles input parameters and whether any input sanitization or validation is presentAffected if The replaceContent function processes user-supplied content without proper sanitization or validation
You are affected if Flute CMS version 0.2.2.4 is installed and the ContentParser.php with its vulnerable replaceContent function is being used by the Notification Handler.

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 dataImplement strict input validation and output encoding in the replaceContent function, and review all user-supplied data paths in the Notification Handler to prevent code injection. Consider using a whitelist approach for allowed content patterns.
