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
Cross-site scripting (XSS) vulnerability in inc/functions_post.php in MyBB (aka MyBulletinBoard) 1.10 allows remote attackers to inject arbitrary web script or HTML via a JavaScript event in a BBCode email tag, as demonstrated using the onmousemove event.

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 · high confidence

Cross-site scripting (XSS) vulnerability in MyBB 1.10's BBCode email tag parser (inc/functions_post.php). Attackers inject arbitrary JavaScript event handlers (e.g., onmousemove) into the email BBCode tag to execute malicious scripts in user browsers.

MitigationSanitize BBCode email tag input by filtering or escaping JavaScript event handler attributes before rendering. Apply output encoding appropriate to the context where the email tag is displayed.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Identify MyBB installation version
    Check your MyBB version by logging into the admin control panel and viewing the version information, or by examining the version file in your MyBB installation directory
    Affected if The installed version is exactly MyBB 1.10
  2. Locate the vulnerable file
    Verify the presence of the file inc/functions_post.php in your MyBB installation directory
    Affected if The file exists and contains BBCode parsing functions for email tags
  3. Confirm BBCode email tag parsing is active
    Check your forum's BBCode settings in the admin control panel under post settings or BBCodes configuration to confirm email tag parsing is enabled
    Affected if Email BBCode tags are permitted and processed by the forum
  4. Examine the email BBCode parser function
    Inspect the functions_post.php file for the email tag parsing logic, specifically looking for how event handlers in email addresses are handled
    Affected if The code does not sanitize or filter JavaScript event handler attributes (such as onmousemove) from email tag input

Your environment is affected if you are running MyBB version 1.10 and the email BBCode feature is enabled, with the vulnerable parsing code present in functions_post.php.

Generated from the published advisory. Verify against your own configuration.
