Security readout for executives and security teams
Plain-English summary
This CVE affects the WordPress Custom Database Applications by Caspio plugin through version 2.1. A DOM-based cross-site scripting flaw could let a lower-privileged attacker cause script execution after user interaction, potentially exposing limited data or changing page behavior.
Executive priority
Treat this as a moderate-priority web application risk. It is not listed as actively exploited in the supplied sources, but affected public WordPress sites should be identified and remediated through vendor guidance to reduce XSS-driven account and data exposure.
Technical view
CVE-2025-31559 is CWE-79 improper input neutralization during webpage generation in custom-database-applications-by-caspio. CVSS 3.1 is 6.5 with network attack vector, low complexity, low privileges required, user interaction required, changed scope, and low confidentiality, integrity, and availability impact.
Likely exposure
Exposure is limited to WordPress sites running the Caspio Custom Database Applications plugin at version 2.1 or earlier. Sites without the plugin, or with unaffected versions, are not indicated as affected in the provided sources.
Exploitation context
The source bundle does not show CISA KEV listing or confirmed active exploitation. The CVSS vector indicates exploitation requires low privileges and user interaction, so practical risk depends on who can access vulnerable plugin functionality and who can be induced to interact.
Researcher notes
Evidence identifies DOM-based XSS in the Caspio WordPress plugin through 2.1. The bundle does not provide a fixed version, proof of exploitation, or detailed vulnerable parameter information. Avoid assuming broader Caspio platform impact beyond the named WordPress plugin package.
Mitigation direction
- Inventory WordPress sites for the custom-database-applications-by-caspio plugin and installed version.
- Check Caspio, WordPress plugin, and Patchstack guidance for an official fixed version.
- Update the plugin if a vendor-supported patched version is available.
- If no fix is available, disable or remove the plugin where business impact allows.
- Limit plugin access to trusted users until vendor guidance is confirmed.
Validation and detection
- Confirm whether any WordPress instance runs Custom Database Applications by Caspio version 2.1 or earlier.
- Record plugin version, site owner, and whether the plugin is active.
- Review relevant pages for untrusted input rendered in plugin-generated content.
- Check logs and security tooling for suspicious script injection indicators.
- Verify remediation by confirming the plugin is patched, disabled, or removed.
