The Eventin WordPress plugin before 4.1.20 does not properly validate a template path setting before using it to include a local file, allowing users with editor-level access and above to include and execute arbitrary local PHP files.
AnalysisAI
Local file inclusion in the Eventin WordPress plugin (all versions before 4.1.20) allows authenticated users holding editor-level or higher WordPress roles to supply an arbitrary local filesystem path as a template setting, causing the plugin to include and execute any reachable PHP file on the server. Full confidentiality, integrity, and availability impact is achievable on a successful exploitation. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires an active WordPress session authenticated at the editor role or higher (corresponding to CVSS PR:H). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 3.1 score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) accurately reflects a high-severity finding that is meaningfully bounded by the requirement for editor-level authentication, which prevents any unauthenticated exploitation path. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | An attacker who possesses or compromises a WordPress account with editor-level privileges accesses the Eventin plugin's template configuration panel and sets the template path to reference a PHP file they have previously placed on the server - for example, a web shell uploaded via WordPress's media upload functionality or another file-write vector. When Eventin renders the template, the PHP runtime executes the attacker-supplied file with the web server process's privileges, enabling arbitrary command execution, database credential extraction, or persistent backdoor installation. … |
| Remediation | The primary remediation is to upgrade the Eventin WordPress plugin to version 4.1.20 or later, which introduces proper validation of the template path setting; this patch is confirmed available via the WordPress plugin repository per the WPScan advisory at https://wpscan.com/vulnerability/c7bdaa80-a446-4c72-be79-bfc5022a4eca/. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all WordPress installations running Eventin and audit accounts with editor-level and administrator permissions to reduce exposure from compromised credentials. …
