{"affected":[],"cveId":"CVE-2026-111592","cwes":["CWE-79"],"description":"The Co-Authors, Multiple Authors and Guest Authors in an Author Box with PublishPress Authors plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'name (maps to display_name)' parameter in all versions up to, and including, 4.17.0 due to insufficient input sanitization and output escaping. 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.","epss":null,"exploits":[],"kev":null,"metrics":[{"score":6.4,"severity":"medium","source":"NVD: security@wordfence.com","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","version":"3.1"}],"modifiedAt":1793557028350,"publishedAt":1793434608463,"references":[{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/publishpress-authors/tags/4.17.0/src/core/Classes/Author_Editor.php#L86"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/publishpress-authors/tags/4.17.0/src/modules/multiple-authors/multiple-authors.php#L302"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/publishpress-authors/tags/4.17.0/src/modules/multiple-authors/multiple-authors.php#L5233"},{"source":"security@wordfence.com","tags":[],"url":"https://plugins.trac.wordpress.org/browser/publishpress-authors/tags/4.18.0/src/core/Classes/Author_Editor.php"},{"source":"security@wordfence.com","tags":[],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/329226bc-7d0e-45e0-8ac0-656517e0e4ca?source=cve"}],"remediation":[],"revision":"d3cf688b377bccd0f0e3b4a64cdd941365f40fcc2f6d2336b8e150cbd3a464d0","sources":[{"modifiedAt":1793557028350,"name":"NVD","retrievedAt":1793578556050,"url":"https://nvd.nist.gov/vuln/detail/CVE-2026-111592"}],"ssvc":{"assessedAt":1793554464057,"automatable":"no","exploitation":"none","source":"NVD SSVC: 134c704f-9b21-4f2e-91b3-4a467353bcc0","technicalImpact":"partial"},"status":"published","title":"CVE-2026-111592","updatedAt":1793578556050}
