Security readout for executives and security teams
Plain-English summary
CVE-2026-1807 affects the InteractiveCalculator WordPress plugin through version 1.0.3. A logged-in user with Contributor-level access or higher can store script content in a shortcode attribute. That script can run when someone views the affected page, creating risk to site users and administrators.
Executive priority
Treat this as a moderate-priority WordPress content integrity issue. It is not reported as actively exploited, but sites with multiple content authors should address it promptly because Contributor accounts can create persistent browser-side risk.
Technical view
The flaw is stored cross-site scripting in the plugin’s interactivecalculator shortcode, specifically the id attribute. Sources attribute it to insufficient input sanitization and output escaping. It is categorized as CWE-79 with CVSS 3.1 score 6.4, requiring low privileges and network access.
Likely exposure
Exposure is limited to WordPress sites running InteractiveCalculator for WordPress versions up to and including 1.0.3, especially sites allowing Contributor or higher accounts to create content containing shortcodes.
Exploitation context
No active exploitation is indicated in the provided sources, and the CVE is not listed as KEV. Exploitation requires an authenticated account with Contributor-level access or higher, but stored XSS can affect later visitors to the injected page.
Researcher notes
The key exposure path is authenticated stored XSS through shortcode attribute handling. Public references include Wordfence vulnerability intelligence and WordPress plugin Trac code/changesets. The source bundle does not provide exploit-in-the-wild evidence or a clearly named fixed version.
Mitigation direction
- Inventory WordPress sites for InteractiveCalculator for WordPress installations.
- Check whether installed versions are 1.0.3 or older.
- Update the plugin beyond affected versions if a vendor-supported release is available.
- If no update is available, follow vendor guidance or disable the plugin.
- Restrict Contributor and higher roles to trusted users only.
- Review existing content using the interactivecalculator shortcode.
Validation and detection
- Confirm plugin presence and version across WordPress assets.
- Review pages and posts for interactivecalculator shortcode usage.
- Look for unusual id attribute values in shortcode content.
- Verify updated code applies sanitization and output escaping for shortcode attributes.
- Check Wordfence or WordPress plugin repository advisories for current remediation status.
