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."}],"title":"Everest Forms <= 3.4.4 - Unauthenticated Server-Side Request Forgery via Upload Field 'Previous Value'","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/c5bbf7ed-c154-4153-adbf-59f0f7aa3a18?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/trunk/includes/class-evf-form-task.php#L1448"},{"url":"https://plugins.trac.wordpress.org/browser/everest-forms/trunk/includes/abstracts/class-evf-form-fields-upload.php#L1196"},{"url":"https://plugins.trac.wordpress.org/changeset/3507814/"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-918 Server-Side Request Forgery (SSRF)","cweId":"CWE-918","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","baseScore":5.3,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"h0xilo"}],"timeline":[{"time":"2026-03-29T06:05:49.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-08-27T00:00:00.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-5096","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-08-28T18:18:07.308946Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-28T18:35:55.807Z"}}]}}
