Security readout for executives and security teams
Plain-English summary
CVE-2026-25407 is a medium-severity access-control flaw in the WordPress Cookiebot plugin. A logged-in user could access something they should not, with limited confidentiality impact. Sources do not report public exploitation or name a fixed version. Sites using Cookiebot at or below the affected version range should verify exposure and follow vendor guidance.
Executive priority
Treat this as a routine but timely WordPress plugin remediation item. It is not currently supported as actively exploited, but affected public websites with many user accounts should prioritize validation and update planning.
Technical view
The CVE describes CWE-862 Missing Authorization in Cookiebot for WordPress, affecting versions through 4.6.4 per the CVE description. CVSS 3.1 is 4.3: network exploitable, low complexity, low privileges required, no user interaction, limited confidentiality impact, no integrity or availability impact. Patchstack is the referenced vulnerability database entry, but provided metadata does not identify a remediation version.
Likely exposure
Exposure is limited to WordPress sites with the Cookiebot plugin installed in the affected range. The attacker must already have low-privileged access, reducing broad internet risk. Validate exact installed plugin versions because the source bundle contains inconsistent version details.
Exploitation context
The CVE is not listed in KEV, and the provided sources do not state active exploitation. The issue requires authenticated access and appears to expose limited information rather than enabling content modification or service disruption.
Researcher notes
Evidence is incomplete on the exact fixed version. The CVE text says through 4.6.4, while the Patchstack URL references 4.6.3. Do not assume a specific patch level from the supplied data; verify against current vendor or Patchstack guidance.
Mitigation direction
- Inventory WordPress sites using the Cookiebot plugin.
- Check installed Cookiebot versions against the CVE and Patchstack entries.
- Review vendor or plugin repository guidance for a fixed release.
- Update the plugin if a vendor-supported fixed version is available.
- Limit unnecessary WordPress user accounts and low-privilege access.
Validation and detection
- Confirm whether the Cookiebot plugin is installed.
- Record the installed Cookiebot plugin version on each site.
- Review WordPress user roles with access to plugin-related areas.
- Check logs for unusual authenticated access to Cookiebot-related endpoints.
- Track Patchstack and CVE updates for remediation clarification.
