Security readout for executives and security teams
Plain-English summary
This WordPress plugin flaw lets a logged-in low-privileged user change redirect behavior without proper authorization. In the worst stated case, they could create a redirect that sends all site traffic to an external malicious website. That can damage trust, interrupt sales or support flows, and expose visitors to phishing or malware.
Executive priority
Handle in normal vulnerability management unless the site allows broad user registration or handles high-trust customer journeys. Prioritize faster remediation for ecommerce, login, healthcare, finance, and brand-sensitive sites because unauthorized redirects can directly affect visitors.
Technical view
CVE-2020-36699 is an authorization bypass in Quick Page/Post Redirect Plugin up to and including 5.1.9. Missing capability checks in qppr_save_quick_redirect_ajax and qppr_delete_quick_redirect allow authenticated low-privileged users to interact with plugin settings. The impact is integrity-focused: unauthorized redirect creation or deletion, with no confidentiality or availability impact claimed by CVSS.
Likely exposure
Exposure is limited to WordPress sites using Quick Page/Post Redirect Plugin versions up to and including 5.1.9, and requires an authenticated low-privileged account. Public sites with open registration, many contributors, or weak account governance have higher practical risk.
Exploitation context
The provided bundle does not show CISA KEV listing or active exploitation evidence. Public advisories document the issue, and one reference title says the vulnerability was unpatched when reported. Treat exploit status as unconfirmed from the supplied evidence.
Researcher notes
The record maps to CWE-284 and CVSS 3.1 score 4.3: AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N. The affected CPE data in the bundle appears sparse, so rely on plugin name and version inventory rather than CPE matching alone.
Mitigation direction
- Inventory WordPress sites for Quick Page/Post Redirect Plugin and installed versions.
- Update beyond version 5.1.9 only using confirmed vendor or WordPress plugin guidance.
- Disable or remove the plugin where a fixed release cannot be confirmed.
- Restrict creation and use of low-privileged WordPress accounts.
- Review configured redirects and remove unexpected external destinations.
Validation and detection
- Confirm whether the plugin is installed and version is 5.1.9 or earlier.
- Review plugin redirect entries for site-wide or unexpected external redirects.
- Verify current plugin code enforces capability checks on redirect save and delete actions.
- Check user audit history for recent redirect configuration changes.
- Monitor for abnormal traffic drops or sudden outbound redirect complaints.

Improper Access Control
Improper Access Control represents a recurring weakness pattern that can create exploitable paths when design, validation, or implementation controls are missing.
