{"id":"CVE-2026-13246","state":"PUBLISHED","title":"GiveWP <= 4.16.0 - Authenticated (Author+) Stored Cross-Site Scripting via 'block_id' Shortcode Attribute","description":"The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'block_id' (and other) shortcode attributes of the 'givewp_campaign_comments' shortcode in versions up to, and including, 4.16.0. This is due to insufficient input sanitization and output escaping on user supplied attributes in CampaignCommentsShortcode::parseAttributes() and BlockRenderController::render(), where the blockId value is interpolated directly into a single-quoted HTML attribute without esc_attr(). This makes it possible for authenticated attackers, with author-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.","publishedAt":"2026-07-01T03:43:33.891Z","updatedAt":"2026-07-01T10:42:12.021Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["stellarwp GiveWP – Donation Plugin and Fundraising Platform"],"affected":[{"vendor":"stellarwp","product":"GiveWP – Donation Plugin and Fundraising Platform","defaultStatus":"unaffected","versions":[{"version":"0","status":"affected","lessThanOrEqual":"4.16.0","versionType":"semver"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/08f8f489-6b31-45d8-a122-bbaa283a2b10?source=cve","https://plugins.trac.wordpress.org/browser/give/trunk/src/Campaigns/Blocks/CampaignComments/Controller/BlockRenderController.php#L23","https://plugins.trac.wordpress.org/browser/give/trunk/src/Campaigns/Shortcodes/CampaignCommentsShortcode.php#L78","https://plugins.trac.wordpress.org/browser/give/trunk/src/Campaigns/Shortcodes/CampaignCommentsShortcode.php#L17","https://plugins.trac.wordpress.org/browser/give/trunk/src/Campaigns/Actions/RegisterCampaignShortcodes.php#L30","https://plugins.trac.wordpress.org/browser/give/trunk/src/Campaigns/Blocks/CampaignComments/render.php#L20","https://plugins.trac.wordpress.org/browser/give/tags/4.16.0/src/Campaigns/Blocks/CampaignComments/Controller/BlockRenderController.php#L23","https://plugins.trac.wordpress.org/browser/give/tags/4.16.0/src/Campaigns/Shortcodes/CampaignCommentsShortcode.php#L78","https://plugins.trac.wordpress.org/browser/give/tags/4.16.0/src/Campaigns/Shortcodes/CampaignCommentsShortcode.php#L17","https://plugins.trac.wordpress.org/browser/give/tags/4.16.0/src/Campaigns/Actions/RegisterCampaignShortcodes.php#L30","https://plugins.trac.wordpress.org/browser/give/tags/4.16.0/src/Campaigns/Blocks/CampaignComments/render.php#L20","https://plugins.trac.wordpress.org/changeset?sfp_email=&sfph_mail=&reponame=&old=3590193%40give&new=3590193%40give&sfp_email=&sfph_mail="],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:11:00.674Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/13xxx/CVE-2026-13246.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-13246","state":"PUBLISHED","datePublished":"2026-07-01T03:43:33.891Z","dateUpdated":"2026-07-01T10:42:12.021Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-06-24T18:03:05.183Z"},"containers":{"cna":{"title":"GiveWP <= 4.16.0 - Authenticated (Author+) Stored Cross-Site Scripting via 'block_id' Shortcode Attribute","descriptions":[{"lang":"en","value":"The GiveWP – Donation Plugin and Fundraising Platform plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'block_id' (and other) shortcode attributes of the 'givewp_campaign_comments' shortcode in versions up to, and including, 4.16.0.
