This is due to insufficient input sanitization and output escaping on the `snapFB` post meta value. 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-2026-3228"}],"fixed_packages":[],"affected_packages":[],"references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2026-3228","reference_id":"","reference_type":"","scores":[{"value":"0.00062","scoring_system":"epss","scoring_elements":"0.19633","published_at":"2026-06-11T12:55:00Z"},{"value":"0.00062","scoring_system":"epss","scoring_elements":"0.19802","published_at":"2026-06-14T12:55:00Z"},{"value":"0.00062","scoring_system":"epss","scoring_elements":"0.19825","published_at":"2026-06-13T12:55:00Z"},{"value":"0.00062","scoring_system":"epss","scoring_elements":"0.19808","published_at":"2026-06-12T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2026-3228"},{"reference_url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/923c51ba-0ec2-4e32-a86e-404f3fe2ac7c?source=cve","reference_id":"923c51ba-0ec2-4e32-a86e-404f3fe2ac7c?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/2026-03-10T15:35:48Z/"}],"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/923c51ba-0ec2-4e32-a86e-404f3fe2ac7c?source=cve"},{"reference_url":"https://plugins.trac.wordpress.org/changeset/3470727/social-networks-auto-poster-facebook-twitter-g/trunk/inc-cl/fb.php","reference_id":"fb.php","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/2026-03-10T15:35:48Z/"}],"url":"https://plugins.trac.wordpress.org/changeset/3470727/social-networks-auto-poster-facebook-twitter-g/trunk/inc-cl/fb.php"},{"reference_url":"https://plugins.trac.wordpress.org/browser/social-networks-auto-poster-facebook-twitter-g/tags/4.4.6/inc-cl/fb.php#L581","reference_id":"fb.php#L581","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/2026-03-10T15:35:48Z/"}],"url":"https://plugins.trac.wordpress.org/browser/social-networks-auto-poster-facebook-twitter-g/tags/4.4.6/inc-cl/fb.php#L581"},{"reference_url":"https://plugins.trac.wordpress.org/browser/social-networks-auto-poster-facebook-twitter-g/trunk/inc-cl/fb.php#L581","reference_id":"fb.php#L581","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/2026-03-10T15:35:48Z/"}],"url":"https://plugins.trac.wordpress.org/browser/social-networks-auto-poster-facebook-twitter-g/trunk/inc-cl/fb.php#L581"}],"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-b81z-8tmp-8qc6"}
