Unauthenticated Broken Access Control in BerqWP <= 4.1.15 versions.
AnalysisAI
Unauthenticated broken access control in the BerqWP WordPress plugin (versions up to and including 4.1.15) lets remote attackers reach functionality that should require authorization, resulting in limited unauthorized modification of site state with no data disclosure or denial of service (CVSS 5.3, AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N). Any WordPress site running an affected version of this niche caching/performance plugin is exposed, though the impact ceiling is low-integrity changes rather than code execution or data theft. …

Vulnerability AssessmentAI
| Exploitation | Requires the target WordPress site to have the BerqWP plugin installed and active at version <= 4.1.15 and network-reachable; exploitation is remote and unauthenticated (PR:N/UI:N) against the affected plugin's exposed endpoint(s). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | Real-world risk is LOW-to-MODERATE despite the unauthenticated remote vector. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | The supplied data does not cite an exact fixed version, so no vendor-released patch can be confirmed at time of analysis; administrators should check the Patchstack advisory and the BerqWP plugin changelog for a release above 4.1.15 and apply it as soon as it is published (WordPress's built-in plugin updater is sufficient once a fixed tag exists). … Detailed patch versions, workarounds, and compensating controls in full report. |
