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. Exploitation requires the attacker's user account to have a mapped author term, which occurs when an administrator has assigned them as a co-author on content or has enabled automatic author term creation for their role — this mapping is not present by default for new users on a stock install."}],"title":"Co-Authors, Multiple Authors and Guest Authors in an Author Box with PublishPress Authors <= 4.17.0 - Authenticated (Subscriber+) Stored Cross-Site Scripting via display_name profile-sync into author term name","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/329226bc-7d0e-45e0-8ac0-656517e0e4ca?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/publishpress-authors/tags/4.17.0/src/core/Classes/Author_Editor.php#L86"},{"url":"https://plugins.trac.wordpress.org/browser/publishpress-authors/tags/4.17.0/src/modules/multiple-authors/multiple-authors.php#L5233"},{"url":"https://plugins.trac.wordpress.org/browser/publishpress-authors/tags/4.17.0/src/modules/multiple-authors/multiple-authors.php#L302"},{"url":"https://plugins.trac.wordpress.org/browser/publishpress-authors/tags/4.18.0/src/core/Classes/Author_Editor.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":"muhammad nizar"}],"timeline":[{"time":"2026-10-16T13:43:43.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-30T19:34:54.000Z","lang":"en","value":"Disclosed"}]}}}
