Free v3.9.9 with support for bootstrap tabs & security fixes is available

As Leaflet Maps Marker runs on your server, delivering a secure product is very important to us.

24 hours ago, we were contacted by Akamai who performed a intensive security review of Leaflet Maps Marker and found 3 potential XSS vulnerabilities. Although the exploitability was reported to be pretty low, we immediately started working on this release, fixing these issues. Many thanks especially to Chad from Akamai for the responsible disclosure!

An update to the latest version is – as always and in this case particularly – highly recommended.

Let me know what you think about this new release by submitting a review!

Maps are now also displayed properly when loaded in bootstrap tabs (as well as jQuery UI tabs which is already supported since v3.6.2).

Other changes and optimizations

  • optimized install- and update routine script (less database queries needed)


  • 3 potential XSS vulnerabilities discovered by Akamai – many thanks for the responsible disclosure!

Known issues

Unfortunately there is currently one issue that cannot be resolved directly within Leaflet Maps Marker:

With WordPress 4.2, Emoji support was added. Unfortunately there is an open bug (details) which can result in frozen maps or crashes on Internet Explorer – so WordPress 4.2, 4.2.1 and 4.2.2 are affected. According to the related trac ticket, a fix is already available and will hopefully be deployed soon with WordPress 4.2.3.

As workaround until WordPress 4.2.3 is available you can only disable Emojis at the moment for maps to also work properly in Internet Explorer.

We am really sorry for this issue, but this is beyond our influence – we already contacted the guys & ladies at WordPress and hope that the fix for the Emoji/SVG bug will be available soon.

Outlook – plans for the next release
