{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/68524?format=json","vulnerability_id":"VCID-rnzv-aucj-a3by","summary":"The Fancy Image Show plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's `fancy-img-show` shortcode in all versions up to, and including, 9.1 due to insufficient input sanitization and output escaping on user supplied attributes. 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.","aliases":[{"alias":"CVE-2026-5340"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-5340","reference_id":"","reference_type":"","scores":[{"value":"0.00034","scoring_system":"epss","scoring_elements":"0.10461","published_at":"2026-06-11T12:55:00Z"},{"value":"0.00034","scoring_system":"epss","scoring_elements":"0.10513","published_at":"2026-06-12T12:55:00Z"},{"value":"0.00039","scoring_system":"epss","scoring_elements":"0.12119","published_at":"2026-06-14T12:55:00Z"},{"value":"0.00039","scoring_system":"epss","scoring_elements":"0.12141","published_at":"2026-06-13T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-5340"},{"reference_url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/131d07ad-4e87-4137-a5df-2b74db1e9ae8?source=cve","reference_id":"131d07ad-4e87-4137-a5df-2b74db1e9ae8?source=cve","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-05-12T12:49:41Z/"}],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/131d07ad-4e87-4137-a5df-2b74db1e9ae8?source=cve"},{"reference_url":"https://plugins.trac.wordpress.org/browser/fancy-image-show/tags/9.1/fancy-image-show.php#L117","reference_id":"fancy-image-show.php#L117","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-05-12T12:49:41Z/"}],"url":"https://plugins.trac.wordpress.org/browser/fancy-image-show/tags/9.1/fancy-image-show.php#L117"},{"reference_url":"https://plugins.trac.wordpress.org/browser/fancy-image-show/tags/9.1/fancy-image-show.php#L178","reference_id":"fancy-image-show.php#L178","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-05-12T12:49:41Z/"}],"url":"https://plugins.trac.wordpress.org/browser/fancy-image-show/tags/9.1/fancy-image-show.php#L178"},{"reference_url":"https://plugins.trac.wordpress.org/browser/fancy-image-show/trunk/fancy-image-show.php#L178","reference_id":"fancy-image-show.php#L178","reference_type":"","scores":[{"value":"6.4","scoring_system":"cvssv3.1","scoring_elements":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N"},{"value":"Track","scoring_system":"ssvc","scoring_elements":"SSVCv2/E:N/A:N/T:P/P:M/B:A/M:M/D:T/2026-05-12T12:49:41Z/"}],"url":"https://plugins.trac.wordpress.org/browser/fancy-image-show/trunk/fancy-image-show.php#L178"}],"weaknesses":[{"cwe_id":79,"name":"Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","description":"The product does not neutralize or incorrectly neutralizes user-controllable input before it is placed in output that is used as a web page that is served to other users."}],"exploits":[],"severity_range_score":"6.4 - 6.4","exploitability":null,"weighted_severity":null,"risk_score":null,"resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-rnzv-aucj-a3by"}
