Security readout for executives and security teams
Plain-English summary
CVE-2026-25389 is a medium-severity information exposure issue in the WordPress EventPrime plugin through version 4.2.8.3. An unauthenticated remote attacker may be able to retrieve embedded sensitive data. The available sources do not name the exposed data type or confirm active exploitation.
Executive priority
Treat as a routine but timely WordPress plugin exposure issue. Prioritize internet-facing sites and sites handling sensitive event, user, or business data. Business urgency is moderate because exploitation appears low-complexity, but the known impact is limited to confidentiality and no active exploitation is cited.
Technical view
The CVE describes CWE-497, Exposure of Sensitive System Information to an Unauthorized Control Sphere, in Metagauss EventPrime eventprime-event-calendar-management. CVSS 3.1 is 5.3: network reachable, low complexity, no privileges, no user interaction, low confidentiality impact, no integrity or availability impact.
Likely exposure
Exposure is most relevant to public WordPress sites running EventPrime through version 4.2.8.3. Sites not using this plugin are not affected based on the provided sources. The affected-version metadata is limited, so plugin inventory should be verified directly.
Exploitation context
The CVSS vector indicates unauthenticated remote access may be sufficient. The source bundle does not provide exploit details, proof-of-concept status, or evidence of active exploitation. This CVE is not marked as CISA KEV in the provided data.
Researcher notes
Public details are sparse. The bundle identifies the vulnerability class and affected range but not the exact data exposed, endpoint behavior, or fixed version. Avoid assuming impact beyond low confidentiality until vendor or Patchstack details provide more evidence.
Mitigation direction
- Identify WordPress sites using the EventPrime plugin.
- Check whether EventPrime is version 4.2.8.3 or earlier.
- Review the vendor or Patchstack advisory for fixed-version guidance.
- Update or disable the plugin if vendor guidance recommends it.
- Restrict unnecessary public exposure of event-related endpoints where operationally feasible.
Validation and detection
- Confirm installed EventPrime versions across WordPress assets.
- Check plugin inventory against the CVE affected range.
- Review web logs for unusual unauthenticated access to EventPrime functionality.
- Monitor vendor, CVE, and Patchstack pages for updated remediation details.
- Document whether the plugin is unused, updated, disabled, or accepted risk.
