This is due to the `rememberLogin` REST API endpoint using a loose comparison (`!=` instead of `!==`) for secret validation at `app/RestAPI.php:111`, combined with no validation that the secret is non-empty. When a target user has never used the \"Remember me\" feature, their `asSecret` user meta does not exist, causing `get_user_meta()` to return an empty string. An attacker can send an empty `secret` parameter, which passes the comparison (`'' != ''` is `false`), and the endpoint then calls `wp_set_auth_cookie()` for the target user. Additionally, all REST routes use `permission_callback => '__return_true'` with no capability checks. This makes it possible for authenticated attackers, with Subscriber-level access and above, to switch to any user account including Administrator, ultimately granting themselves full administrative privileges.","published_at":"2026-05-20T01:25:51.165000Z","last_modified_at":null,"cvss_v3_score":8.8,"cvss_v3_vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","cvss_v3_severity":"HIGH","cvss_v4_score":null,"cvss_v4_vector":null,"cvss_v4_severity":null,"ssvc_decision":null,"ssvc_exploitation":null,"ssvc_automatable":null,"ssvc_technical_impact":null,"cwes":["CWE-287"],"nvd_references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/9e9cfb9b-6951-4246-9cd6-dd64fee3a1bc?source=cve","https://plugins.trac.wordpress.org/browser/account-switcher/tags/1.0.2/app/RestAPI.php#L111","https://plugins.trac.wordpress.org/browser/account-switcher/tags/1.0.2/app/PluginHero/BaseAPI.php#L54","https://wordpress.org/plugins/account-switcher/"],"vuln_status":null,"trending_score":null,"is_trending":false,"has_trended":false,"trended_number_one":false,"trending_peak_score":null,"trending_peak_rank":null,"started_trending_at":null,"trended_number_one_at":null,"summary_generated":null,"summary_generated_at":null,"summary_model":null,"created_at":"2026-06-24T00:09:39.878444Z","updated_at":"2026-06-28T23:31:01.784289Z"},"effective_severity":"HIGH","badges":[],"impact_analysis":[],"cvss_v3_decoded":{"version":"3.1","metrics":[{"metric":"AV","name":"Attack Vector","value":"N","value_label":"Network"},{"metric":"AC","name":"Attack Complexity","value":"L","value_label":"Low"},{"metric":"PR","name":"Privileges Required","value":"L","value_label":"Low"},{"metric":"UI","name":"User Interaction","value":"N","value_label":"None"},{"metric":"S","name":"Scope","value":"U","value_label":"Unchanged"},{"metric":"C","name":"Confidentiality","value":"H","value_label":"High"},{"metric":"I","name":"Integrity","value":"H","value_label":"High"},{"metric":"A","name":"Availability","value":"H","value_label":"High"}]},"cvss_v4_decoded":{"version":null,"metrics":[]},"affected":[{"vendor_slug":"beycanpress","vendor_name":"beycanpress","product_slug":"account-switcher","product_name":"Account Switcher","version_start":"0","version_start_inclusive":true,"version_end":"1.0.2","version_end_inclusive":true,"cpe23_uri":"cve5:beycanpress:account-switcher:0:1.0.2"}],"exploit_refs":[],"news":[],"references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/9e9cfb9b-6951-4246-9cd6-dd64fee3a1bc?source=cve","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/account-switcher/tags/1.0.2/app/RestAPI.php#L111","source_type":"MISC","tags":[]},{"url":"https://plugins.trac.wordpress.org/browser/account-switcher/tags/1.0.2/app/PluginHero/BaseAPI.php#L54","source_type":"MISC","tags":[]},{"url":"https://wordpress.org/plugins/account-switcher/","source_type":"MISC","tags":[]}],"timeline":[{"type":"published","at":"2026-05-20T01:25:51.165000Z","label":"CVE published","source":null},{"type":"cvss_changed","at":"2026-06-28T17:56:01.087206Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:56:01.087206Z","label":"CVSS score revised","source":"cvelistv5"},{"type":"cvss_changed","at":"2026-06-28T17:56:01.087206Z","label":"CVSS score revised","source":"cvelistv5"}]}
