This is due to the plugin saving the image-alt field through sanitize_text_field() in Inc/Style22::register_child() (and Inc/Style18, 19, 20, 25, 29) \u2014 which preserves the double-quote character \u2014 and then concatenating the stored value into a double-quoted HTML attribute in Public_Render/Style22::default_render() (and the corresponding Style18/19/20/25/29 renderers) with no esc_attr() escaping. This makes it possible for authenticated attackers, with contributor-level access and above (when an administrator has delegated the plugin's 'Who can edit' capability via the plugin Settings page, or on multisite installations where even administrators lack unfiltered_html), to inject arbitrary web scripts in pages that will execute whenever a user accesses any page containing an affected [oxilab_flip_box] shortcode or block."}], "title": "Flipbox <= 3.1.1 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'flip-box-image-upload-url-01-alt' Parameter", "references": [{"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/c3403cd6-31ba-4c36-a60e-d3e5c038af78?source=cve"}, {"url": "https://plugins.trac.wordpress.org/browser/image-hover-effects-ultimate-visual-composer/tags/3.1.0/Public_Render/Style22.php#L58"}, {"url": "https://plugins.trac.wordpress.org/browser/image-hover-effects-ultimate-visual-composer/tags/3.1.0/Inc/Style22.php#L169"}, {"url": "https://plugins.trac.wordpress.org/browser/image-hover-effects-ultimate-visual-composer/tags/3.1.0/Page/Admin_Render.php#L128"}, {"url": "https://plugins.trac.wordpress.org/browser/image-hover-effects-ultimate-visual-composer/tags/3.1.0/Includes/Admin/Menu.php#L53"}, {"url": "https://plugins.trac.wordpress.org/changeset?reponame=&old=3762680%40image-hover-effects-ultimate-visual-composer&new=3762680%40image-hover-effects-ultimate-visual-composer"}], "problemTypes": [{"descriptions": [{"lang": "en", "description": "CWE-79 Improper Neutralization of Input During Web Page Generation", "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": "2026-11-04T00:26:05.000Z", "lang": "en", "value": "Vendor Notified"}, {"time": "2026-11-07T00:15:12.000Z", "lang": "en", "value": "Disclosed"}]}, "adp": [{"metrics": [{"other": {"type": "ssvc", "content": {"id": "CVE-2026-109973", "role": "CISA Coordinator", "options": [{"Exploitation": "none"}, {"Automatable": "no"}, {"Technical Impact": "partial"}], "version": "2.0.3", "timestamp": "2026-11-07T17:58:35.439374Z"}}}], "title": "CISA ADP Vulnrichment", "providerMetadata": {"orgId": "134c704f-9b21-4f2e-91b3-4a467353bcc0", "shortName": "CISA-ADP", "dateUpdated": "2026-11-07T18:05:58.418Z"}}]}}
