CVE-2026-42676
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 · uneditedImproper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in myCred allows Stored XSS. This issue affects myCred: from n/a through 3.0.4.
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 confidenceStored XSS vulnerability in myCred plugin versions up to 3.0.4 allows authenticated or unauthenticated attackers to inject malicious JavaScript through unsanitized user input that gets stored in the database and executed when other users view affected pages.

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 myCred plugin is installedAccess WordPress admin panel, navigate to Plugins > Installed Plugins, or inspect the /wp-content/plugins/ directory for the myCred folderAffected if myCred plugin is present in the WordPress installation
-
Determine installed myCred versionIn WordPress admin, go to Plugins > Installed Plugins and find the myCred plugin version number, or read the version from the plugin's main PHP file or readme.txtAffected if installed version is 3.0.4 or lower (any version up to and including 3.0.4)
-
Identify active myCred components that store user dataReview myCred log entries, point balance history, custom shortcodes, or any myCred add-ons that collect and store user-supplied input (such as custom point types, badges, or rewards)Affected if any myCred component is storing user-submitted data in the database
-
Inspect rendered output for stored contentView web pages where myCred displays stored user data (such as user profiles, leaderboards, or log displays) and view the page source to check if data is rendered with proper HTML encodingAffected if user-supplied content stored by myCred appears unencoded in HTML output
Your environment is affected if myCred plugin versions 3.0.4 or lower are installed and any myCred-stored user content is rendered on web pages.

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 dataUpdate myCred to the latest version when available. Until then, implement output encoding and input sanitization using WordPress sanitization functions (sanitize_text_field, esc_html, esc_attr) on all user-supplied data before database storage and before rendering in web pages.
