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 phpMyChat-Plus installationSearch the web server document root for phpMyChat-Plus files. Look for directories containing chat-related PHP files or configuration files typical of this application.Affected if phpMyChat-Plus is present on the server
-
Determine installed versionOpen the main index file or any include/version file in the phpMyChat-Plus directory and locate the version string. Compare it against the affected version 1.98.Affected if The installed version is exactly 1.98
-
Verify pass_reset.php existsCheck for the presence of pass_reset.php in the phpMyChat-Plus installation directory.Affected if pass_reset.php file exists in the application
-
Confirm pmc_username parameter handlingExamine the pass_reset.php source code to verify it processes the pmc_username parameter without proper input validation or output encoding.Affected if pass_reset.php reflects the pmc_username parameter into the page output without sanitization
If phpMyChat-Plus version 1.98 is installed with pass_reset.php present and the pmc_username parameter is processed unsafely, the environment is affected by this reflected XSS vulnerability.

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 proper input validation and output encoding for the pmc_username parameter in pass_reset.php. Use context-appropriate escaping when reflecting user input back into HTML/JavaScript contexts.
