{"schema":"threatline.record/2","record":{"id":"CVE-2026-109385","aliases":[],"summary":"UiChemy <= 5.3.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via Slot Link URL","details":"The UiChemy – Convert Figma, Prompts and AI Builds to Elementor, Gutenberg and Bricks plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'actions[save_builder][data][elements][...][settings][slot_{N}_link][url]' parameter in all versions up to, and including, 5.3.0 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 injected javascript: payload fires on click rather than on page load, making exploitation contingent on a privileged user such as an Editor or Administrator clicking the attacker-crafted link while reviewing or previewing the Contributor's post.","categories":["Unclassified"],"product":"UiChemy – Convert Figma, Prompts and AI Builds to Elementor, Gutenberg and Bricks","vendor":"posimyththemes","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-109385","source_modified_at":"2026-10-28T06:45:07.291Z","fetched_at":"2026-10-28T08:18:35.509402Z","product":"UiChemy – Convert Figma, Prompts and AI Builds to Elementor, Gutenberg and Bricks","vendor":"posimyththemes","versions":[{"version":"0","status":"affected","lessThanOrEqual":"5.3.0","versionType":"semver"}],"defaultStatus":"unaffected"}],"fixed_versions":[],"cvss":6.4,"severity":"Medium","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-28T06:45:07.291Z","modified_at":"2026-10-28T06:45:07.291Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-109385","fetched_at":"2026-10-28T08:18:35.509402Z","source_modified_at":"2026-10-28T06:45:07.291Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/1fdc5c50-1d5b-4141-9524-f0e01c097a87?source=cve"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/uichemy/tags/5.2.5/uichemy-composer/includes/admin/widgets/class-uichemy-composer-widget.php#L1428"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/uichemy/tags/5.2.5/uichemy-composer/includes/admin/widgets/class-uichemy-composer-widget.php#L3580"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/uichemy/tags/5.2.5/uichemy-composer/includes/admin/widgets/class-uichemy-composer-widget.php#L476"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/browser/uichemy/tags/5.2.5/uichemy-composer/includes/admin/class-uichemy-composer-manager.php#L3746"},{"source":"CVE List","url":"https://wordpress.org/plugins/uichemy/"},{"source":"CVE List","url":"https://plugins.trac.wordpress.org/changeset/3754473/uichemy/trunk/uichemy-composer/includes/admin/widgets/class-uichemy-composer-widget.php"}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-28T06:45:07.291Z","content_hash":"a58d696fd86b95deb1424537665a462138ec1e1064e93aeabec9efd3d0249f04"}}
