This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This is exploitable by any Subscriber who sets their display_name to a string containing the literal %%archive_title%% token alongside HTML event-handler payloads, as WordPress stores display names without HTML filtering and the plugin substitutes the token after escaping has already occurred."}],"title":"SEOPress <= 10.3 - Authenticated (Subscriber+) Stored Cross-Site Scripting via 'display_name' Profile Field via %%archive_title%% Template Tag","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/6651c932-aa60-485b-bb5b-b66d5a8963ae?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/options-social.php#L533"},{"url":"https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/options-social.php#L542"},{"url":"https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/options-social.php#L1104"},{"url":"https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/options-social.php#L1112"},{"url":"https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/variables/dynamic-variables.php#L340"},{"url":"https://plugins.trac.wordpress.org/browser/wp-seopress/tags/10.3/inc/functions/options-titles-metas.php#L403"},{"url":"https://plugins.svn.wordpress.org/wp-seopress/trunk/"},{"url":"https://plugins.trac.wordpress.org/changeset/3772366/wp-seopress/trunk/inc/functions/options-social.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":6.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Yuto Hyakumoto"}],"timeline":[{"time":"2026-10-26T14:46:21.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-30T18:56:36.000Z","lang":"en","value":"Disclosed"}]}}}
