Imported item content is taken raw from $item->get_content(), only entity-decoded, and stored verbatim in post_content. This makes it possible for unauthenticated attackers, who publish or compromise an RSS feed that an administrator has subscribed a WPeMatico campaign to, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected imported post."}],"title":"WPeMatico RSS Feed Fetcher <= 2.9 - Unauthenticated Stored Cross-Site Scripting via RSS Feed Content Import","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/e87fc1bf-af05-4089-a164-8a2e73c68e8c?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/wpematico/tags/2.9/includes/campaign_fetch.php#L400"},{"url":"https://plugins.trac.wordpress.org/browser/wpematico/tags/2.9/includes/wpematico_functions.php#L3226"},{"url":"https://plugins.trac.wordpress.org/browser/wpematico/tags/2.9/includes/campaign_fetch.php#L777"},{"url":"https://plugins.trac.wordpress.org/browser/wpematico/tags/2.9/includes/campaign_fetch.php#L773"},{"url":"https://plugins.trac.wordpress.org/browser/wpematico/tags/2.9/includes/wpematico_functions.php#L3326"},{"url":"https://github.com/etruel/wpematico/commit/44c4894a0ad92a711c534ad4d822c0b5d7c3dffe"},{"url":"https://plugins.trac.wordpress.org/changeset/3747465/wpematico/trunk/includes/campaign_fetch.php"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:C/C:L/I:L/A:N","baseScore":5.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Elieve"}],"timeline":[{"time":"2026-10-13T18:24:50.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-15T17:49:04.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-110252","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-10-16T14:33:52.898447Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-16T14:39:02.268Z"}}]}}
