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. The payload is not neutralized at save time because post_content stores only a benign block reference to an external feed URL; the malicious HTML is injected at render time from the attacker-controlled RSS feed title, bypassing any save-time wp_kses filtering."}],"title":"RSS Aggregator by Feedzy <= 5.2.10 - Authenticated (Contributor+) Stored Cross-Site Scripting via Feedzy Loop Block Feed URL / RSS <title>","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/a15a6cf2-aa7d-454c-83d2-9d74ce4505be?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/feedzy-rss-feeds/tags/5.2.10/includes/gutenberg/feedzy-rss-feeds-loop-block.php#L207"},{"url":"https://plugins.trac.wordpress.org/browser/feedzy-rss-feeds/tags/5.2.10/includes/gutenberg/feedzy-rss-feeds-loop-block.php#L262"},{"url":"https://plugins.trac.wordpress.org/browser/feedzy-rss-feeds/tags/5.2.10/includes/gutenberg/feedzy-rss-feeds-loop-block.php#L241"},{"url":"https://plugins.trac.wordpress.org/browser/feedzy-rss-feeds/tags/5.2.10/includes/abstract/feedzy-rss-feeds-admin-abstract.php#L1758"},{"url":"https://downloads.wordpress.org/plugin/feedzy-rss-feeds.5.2.11.zip"}],"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:L/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":6.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Wordfence PRISM"}],"timeline":[{"time":"2026-10-02T12:06:27.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-10-09T15:41:09.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"id":"CVE-2026-104735","role":"CISA Coordinator","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"version":"2.0.3","timestamp":"2026-10-11T12:17:38.897732Z"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-11T12:23:58.816Z"}}]}}
