{"id":"CVE-2026-8898","state":"PUBLISHED","title":"Events In City <= 3.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","description":"The Events In City plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'org-events' shortcode in versions up to, and including, 3.0. This is due to insufficient input sanitization and output escaping on user supplied attributes (such as 'organizer_id', 'width', 'height', 'transparency', 'header', 'border', and 'layout') in the org_event_scode() function. The attribute values are concatenated directly into HTML attributes without esc_attr(). This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","publishedAt":"2026-05-27T05:31:24.690Z","updatedAt":"2026-05-27T10:36:49.318Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["ruchit47 Events In City"],"affected":[{"vendor":"ruchit47","product":"Events In City","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"3.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/4281ad41-d9a4-4503-9238-24990641a9bf?source=cve","https://plugins.trac.wordpress.org/browser/events-in-city/tags/3.0/ae_org_widget.php#L156","https://plugins.trac.wordpress.org/browser/events-in-city/tags/3.0/ae_org_widget.php#L144"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/8xxx/CVE-2026-8898.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-8898","state":"PUBLISHED","datePublished":"2026-05-27T05:31:24.690Z","dateUpdated":"2026-05-27T10:36:49.318Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-18T21:10:14.369Z"},"containers":{"cna":{"title":"Events In City <= 3.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","descriptions":[{"lang":"en","value":"The Events In City plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'org-events' shortcode in versions up to, and including, 3.0.
