Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires the Popup by Supsystic plugin (version <= 1.13.0) to be installed and active on a network-reachable WordPress site, with the vulnerable authentication-bypass code path exposed. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Signals are mixed. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker sends a crafted unauthenticated HTTP request directly to the plugin's vulnerable AJAX/REST action on a public WordPress site, invoking privileged functionality without logging in. Because attack complexity is low and no user interaction is needed, this can be scripted against many sites; no public POC is identified at this time. |
| Remediation | No vendor-released patch version is confirmed in the available data; the affected range is <= 1.13.0, so upgrade to the next release above 1.13.0 once the vendor publishes it and confirm the fixed version via the Patchstack advisory (https://patchstack.com/database/wordpress/plugin/popup-by-supsystic/vulnerability/wordpress-popup-by-supsystic-plugin-1-13-0-broken-authentication-vulnerability). … Detailed patch versions, workarounds, and compensating controls in full report. |
