Analyst readout for executives and security teams
Plain-English summary
A WordPress cookie-advice plugin for Spanish compliance had a stored cross-site scripting issue in versions through 3.4.3. An administrator-level user could save content that later runs in another user’s browser. Business risk is mainly for sites with multiple admins or compromised admin accounts.
Executive priority
Treat as a moderate-priority WordPress hygiene issue. It is not currently evidenced as exploited, but it matters where the plugin is present on public sites or where admin accounts are shared, stale, or weakly protected.
Technical view
CVE-2022-40697 is CWE-79 stored XSS in 3COM Marketing’s 3com – Asesor de Cookies para normativa española WordPress plugin <= 3.4.3. The CVSS 3.1 score is 4.8, with network access, low attack complexity, high privileges required, user interaction required, changed scope, low confidentiality and integrity impact, and no availability impact.
Likely exposure
Exposure is limited to WordPress installations using the affected plugin version. The source bundle does not provide CPEs or detailed affected-version metadata beyond the <= 3.4.3 statement.
Exploitation context
The bundle does not identify active exploitation, and the CVE is not marked in KEV. Exploitation requires an authenticated administrator-level user and user interaction, so unmanaged admin access or compromised admin accounts are the main concern.
Researcher notes
Evidence is sparse: the bundle names authenticated admin+ stored XSS, CVSS details, CWE-79, and Patchstack as the vulnerability database source. It does not include affected endpoints, proof details, exploit status, or a named fixed version.
Mitigation direction
- Inventory WordPress sites for this plugin and version.
- Review vendor or Patchstack guidance for fixed release availability.
- Update if a fixed version is available and tested.
- Disable or remove the plugin if it is not required.
- Restrict administrator access to trusted accounts only.
- Review administrator account security and MFA coverage.
Validation and detection
- Confirm whether the plugin is installed on each WordPress site.
- Record installed plugin versions and flag versions <= 3.4.3.
- Review admin account lists for unnecessary privileged users.
- Check security advisories for remediation guidance or fixed versions.
- Review recent admin activity for unexpected plugin setting changes.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
