Security readout for executives and security teams
Plain-English summary
CVE-2026-25331 is a medium-severity cross-site scripting issue in the WordPress WP Activity Log plugin, affecting versions through 5.5.4. An attacker with some level of access would need user interaction to trigger it. Successful exploitation could expose or alter limited data in a user’s browser session.
Executive priority
Treat this as a routine but time-sensitive WordPress plugin remediation. Prioritize externally facing or business-critical WordPress sites, especially where multiple users have dashboard access. It is not currently evidenced as actively exploited in the provided sources.
Technical view
The issue is a DOM-based XSS vulnerability caused by improper neutralization of input during web page generation in Melapress WP Activity Log, package wp-security-audit-log. CVSS 3.1 is 6.5: network reachable, 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 WP Activity Log versions up to and including 5.5.4. Risk is higher for sites where untrusted or lower-privileged users can access plugin-related administrative workflows.
Exploitation context
The CVE record does not indicate known active exploitation, and it is not listed as CISA KEV in the provided data. Exploitation requires authenticated access and user interaction, reducing urgency compared with unauthenticated server-side flaws.
Researcher notes
Evidence is limited to the CVE entry and Patchstack database reference. The vulnerability is categorized as CWE-79 DOM-based XSS with PR:L and UI:R. No exploit details, proof-of-concept status, or explicit fixed version are included in the provided bundle.
Mitigation direction
- Inventory WordPress sites using the WP Activity Log plugin.
- Identify installed plugin versions and flag versions 5.5.4 or earlier.
- Check Melapress and Patchstack guidance for the fixed release or recommended mitigation.
- Update the plugin if a vendor-confirmed fixed version is available.
- Restrict plugin administration access to trusted users until remediated.
Validation and detection
- Confirm the plugin package name is wp-security-audit-log.
- Record the installed WP Activity Log version from WordPress administration or asset inventory.
- Compare installed versions against the affected range: through 5.5.4.
- Review user roles that can access plugin pages or related audit-log workflows.
- Monitor vendor advisories for clarification on fixed versions and remediation status.
