{"cve":"CVE-2026-13246","nvd":{"published":"2026-07-01T05:16:18.333","modified":"2026-07-01T13:56:17.493","status":"Deferred","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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","score":6.4},"cwes":["CWE-79"],"references":["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/Controller/BlockRenderController.php#L23","https://plugins.trac.wordpress.org/browser/give/tags/4.16.0/src/Campaigns/Blocks/CampaignComments/render.php#L20","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/Shortcodes/CampaignCommentsShortcode.php#L78"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:42:16.820116992+00:00"},"epss":{"cve":"CVE-2026-13246","score":0.00419,"percentile":0.36221,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
