Security readout for executives and security teams
Plain-English summary
This vulnerability lets a logged-in WordPress user with author-level or higher privileges store malicious script through the Pricing Table plugin. The impact is limited by the need for an account and victim interaction, but it can still affect administrators or visitors who view the stored content.
Executive priority
Treat as a moderate web security issue. It is not currently sourced as exploited in the wild, but affected public WordPress sites with multiple authors should remediate promptly to reduce account-abuse and stored XSS risk.
Technical view
CVE-2021-36896 is authenticated stored XSS in W3 Eden Pricing Table for WordPress versions 1.5.2 and earlier. The CVSS 3.1 score is 4.8, reflecting network access, low attack complexity, high privileges required, required user interaction, changed scope, and low confidentiality/integrity impact.
Likely exposure
WordPress sites running the Pricing Table plugin version 1.5.2 or earlier are in scope. Risk is higher on multi-author sites or sites where author, editor, or administrator accounts may be compromised. The source bundle does not identify other affected products or platforms.
Exploitation context
The provided sources do not state active exploitation, and the CVE is not marked as CISA KEV. Exploitation requires an authenticated author-or-higher WordPress account and a victim viewing affected stored content. No exploit details should be assumed from the available evidence.
Researcher notes
Evidence supports CWE-79 authenticated stored XSS affecting Pricing Table <= 1.5.2. The bundle does not name a fixed version, vulnerable parameter, payload, or exploit chain. Validation should focus on plugin version, role exposure, and vendor-confirmed remediation status.
Mitigation direction
- Check official plugin and vendor guidance for a fixed version.
- Upgrade Pricing Table if a vendor-confirmed fixed release is available.
- Disable or remove the plugin if no safe version is confirmed.
- Restrict author-or-higher accounts to trusted users only.
- Review privileged WordPress accounts for compromise or unnecessary access.
Validation and detection
- Inventory WordPress sites for the Pricing Table plugin.
- Confirm installed plugin versions are greater than 1.5.2 or vendor-confirmed fixed.
- Review user roles with author, editor, or administrator privileges.
- Inspect recent Pricing Table content changes by privileged users.
- Check security monitoring for unusual script injection indicators.
