WPLMS plugin: Blind SQL injection
Summary
The WPLMS WordPress learning management plugin before version 1.9.9.8.2 contains a blind SQL injection vulnerability. An unauthenticated remote attacker can send crafted requests to extract database contents, which may include user accounts and private data. Patchstack rates the issue as critical (CVSS 9.3) and reports no known exploitation at the time of writing.
Affected
- WPLMS WordPress plugin (wplms_plugin) versions before 1.9.9.8.2
- Whether the WPLMS theme versions are affected is unknown.
Fixed in
- Version 1.9.9.8.2 of the WPLMS plugin (per the CVE record and Patchstack)
Workaround
- No vendor workaround known.
- Patchstack has issued a mitigation rule; availability for your setup is unknown.
- Generic measures such as restricting access to WPLMS endpoints and using a WAF with SQL injection rules may reduce risk until patching is complete.
Exploitation
- CISA KEV: not listed.
- EPSS: 0.0025.
- Public proof of concept: none found, not confirmed absent.
- Exploited in the wild: no evidence found, status unknown.
- Patchstack describes the issue as expected to be exploited and used in mass-exploit campaigns.
Our recommendation
- Identify all WPLMS installations and confirm whether the plugin or the theme is in use and at which version.
- Update the WPLMS plugin to version 1.9.9.8.2 or later immediately.
- If patching is not possible right away, restrict access to affected endpoints and enable WAF protection.
- Review web server and WAF logs for SQL injection patterns.
- Check for new proof-of-concept code and KEV listing, as NVD analysis is still pending.
