This is due to the `load_previous_field_value()` method in `class-evf-form-task.php` accepting arbitrary URL values from `$_POST` data for upload fields without domain restriction, which are then passed to `wp_remote_head()` in the `get_local_file_size()` method of `class-evf-form-fields-upload.php`. This makes it possible for unauthenticated attackers to force the WordPress server to make outbound HTTP HEAD requests to arbitrary URLs by submitting a form with an upload field containing a malicious URL while leaving a required field empty to trigger form re-rendering."}],"id":"CVE-2026-5096","lastModified":"2026-08-28T20:19:02.463","metrics":{"cvssMetricV31":[{"cvssData":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"NONE","baseScore":5.3,"baseSeverity":"MEDIUM","confidentialityImpact":"LOW","integrityImpact":"NONE","privilegesRequired":"NONE","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"exploitabilityScore":3.9,"impactScore":1.4,"source":"security@wordfence.com","type":"Secondary"}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"id":"CVE-2026-5096","options":[{"exploitation":"none"},{"automatable":"yes"},{"technicalImpact":"partial"}],"role":"CISA Coordinator","timestamp":"2026-08-28T18:18:07.308946Z","version":"2.0.3"}}]},"published":"2026-08-28T16:18:18.820","references":[{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/everest-forms/trunk/includes/abstracts/class-evf-form-fields-upload.php#L1196"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/everest-forms/trunk/includes/class-evf-form-task.php#L1448"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/changeset/3507814/"},{"source":"security@wordfence.com","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/c5bbf7ed-c154-4153-adbf-59f0f7aa3a18?source=cve"}],"sourceIdentifier":"security@wordfence.com","vulnStatus":"Deferred","weaknesses":[{"description":[{"lang":"en","value":"CWE-918"}],"source":"security@wordfence.com","type":"Secondary"}]}
