MapSVG WordPress plugin: SQL injection
Summary
The MapSVG WordPress plugin up to and including version 8.16.1 contains an SQL injection flaw (CWE-89). According to Patchstack, an attacker with a Contributor account or higher can inject SQL commands and could read, modify or delete database content, including user accounts. The CVSS score is 8.5, but Patchstack rates the priority as low and considers exploitation unlikely, and NVD analysis was still pending when this entry was written.
Affected
- MapSVG WordPress plugin up to and including 8.16.1
- Lower bound of the affected range not stated in the CVE record
- VulDB lists 8.16.0 and 8.16.1 as affected
Fixed in
- Version 8.16.2 (according to WPScan; not confirmed on the Patchstack page)
- Latest release at the time of research: 8.16.3
Workaround
- No vendor or Patchstack workaround known. Patching is the required action.
- Interim measure if an update is delayed: limit Contributor-level and higher WordPress accounts to trusted users.
Exploitation
- No public exploit known; no CISA KEV entry found
- Patchstack and CISA SSVC: exploitation none, not automatable
- VulDB rates the threat as low; EPSS 0.0026
- No reports of in-the-wild exploitation found; this means not known, not confirmed absent
Our recommendation
- Inventory WordPress sites that run the MapSVG plugin and check their versions
- Update to 8.16.2 or later, preferably 8.16.3
- Review accounts with Contributor or higher rights and remove unused ones
- Check logs and the database for unusual queries against plugin endpoints
- Prioritise public WordPress sites with several editors
