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.","state":0,"publishedAt":"2026-10-10T04:26:45.965+00:00","modifiedAt":"2026-10-11T12:23:58.816+00:00","affected":[{"ecosystem":"Vendor product","name":"RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"themeisle\",\n                    \"product\": \"RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator\",\n                    \"versions\": [\n                        {\n                            \"version\": \"0\",\n                            \"status\": \"affected\",\n                            \"lessThanOrEqual\": \"5.2.10\",\n                            \"versionType\": \"semver\"\n                        }\n                    ],\n                    \"defaultStatus\": \"unaffected\"\n                }"}],"metrics":[{"system":"CVSS 3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4,"severity":"MEDIUM"}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/a15a6cf2-aa7d-454c-83d2-9d74ce4505be?source=cve","https://plugins.trac.wordpress.org/browser/feedzy-rss-feeds/tags/5.2.10/includes/gutenberg/feedzy-rss-feeds-loop-block.php#L207","https://plugins.trac.wordpress.org/browser/feedzy-rss-feeds/tags/5.2.10/includes/gutenberg/feedzy-rss-feeds-loop-block.php#L262","https://plugins.trac.wordpress.org/browser/feedzy-rss-feeds/tags/5.2.10/includes/gutenberg/feedzy-rss-feeds-loop-block.php#L241","https://plugins.trac.wordpress.org/browser/feedzy-rss-feeds/tags/5.2.10/includes/abstract/feedzy-rss-feeds-admin-abstract.php#L1758","https://downloads.wordpress.org/plugin/feedzy-rss-feeds.5.2.11.zip"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-104735","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-104735","identifiers":["CVE-2026-104735"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
