{"schema":"threatline.record/2","record":{"id":"CVE-2026-104735","aliases":[],"summary":"RSS Aggregator by Feedzy <= 5.2.10 - Authenticated (Contributor+) Stored Cross-Site Scripting via Feedzy Loop Block Feed URL / RSS <title>","details":"The RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Feedzy Loop Block Feed URL / RSS <title> in all versions up to, and including, 5.2.10 due to insufficient input sanitization and output escaping. 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.","categories":["Unclassified"],"product":"RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator","vendor":"themeisle","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-104735","source_modified_at":"2026-10-11T12:23:58.816Z","fetched_at":"2026-10-23T18:48:36.087640Z","product":"RSS Aggregator by Feedzy – Feed to Post, Autoblogging, News & YouTube Video Feeds Aggregator","vendor":"themeisle","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.2.10","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":0.00216,"percentile":0.11395,"score_date":"2026-10-23"},"published_at":"2026-10-10T04:26:45.965Z","modified_at":"2026-10-11T12:23:58.816Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-104735","fetched_at":"2026-10-23T18:48:36.087640Z","source_modified_at":"2026-10-11T12:23:58.816Z"},{"source":"EPSS","url":"https://api.first.org/data/v1/epss?cve=CVE-2026-104735","fetched_at":"2026-10-23T18:42:43.628194Z","source_modified_at":"2026-10-23"}],"sources":["CVE List","EPSS"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/a15a6cf2-aa7d-454c-83d2-9d74ce4505be?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/feedzy-rss-feeds/tags/5.2.10/includes/gutenberg/feedzy-rss-feeds-loop-block.php#L207"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/feedzy-rss-feeds/tags/5.2.10/includes/gutenberg/feedzy-rss-feeds-loop-block.php#L262"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/feedzy-rss-feeds/tags/5.2.10/includes/gutenberg/feedzy-rss-feeds-loop-block.php#L241"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/feedzy-rss-feeds/tags/5.2.10/includes/abstract/feedzy-rss-feeds-admin-abstract.php#L1758"},{"source":"CVE List","url":"https://downloads.wordpress.org/plugin/feedzy-rss-feeds.5.2.11.zip"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","ssvc":{"exploitation":"none","automatable":"no","technical_impact":"partial","assessed_at":"2026-10-11T12:17:38.897732Z"},"classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-11T12:23:58.816Z","content_hash":"7cf168085195444675d96cb293962c1150efe3084b0989cba0e0da9f2c09217c"}}
