MapSVG loading text permits contributor stored XSS
MapSVG through 8.14.0 permits a contributor-controlled persisted loadingText map option to reach the public data-loading-text attribute and administrator-localized map options without contextual sanitization. Script-bearing option content can therefore execute when the affected map is rendered.

8.14.2- Published
- Jul 24, 2026
This CVE was published Jul 24, 2026 and is one of 12 known issues for this plugin.
Update, patch or deactivate.
Update MapSVG to 8.14.2 or later. For a source backport, sanitize loadingText when saving map options and escape it again for the data-loading-text and localized-output contexts. Review existing map loading-text options for unexpected markup.
A safe version is available, so updating to that version or later is the preferred remediation. If an immediate update is not practical, consider a targeted application patch or temporarily restricting the affected functionality.
Deactivate only when warranted by your risk profile, or when advised by your hosting provider in the limited circumstances where the vulnerability cannot otherwise be mitigated. If you’re unsure which action is appropriate, contact Fused or your hosting provider for guidance.
Technical description
The MapSVG plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 8.14.0. This is due to insufficient input sanitization and output escaping on user supplied attributes within the map options. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
