This is due to insufficient output escaping in the as_get_coin_shortcode() function, which renders the 'width' (and 'height') shortcode attribute directly into the style attribute of an <iframe> element without applying any escaping function such as esc_attr(). An attacker-controlled value like '100px;\"onload=\"alert(1)\" x=\"' terminates the style attribute prematurely and injects an arbitrary HTML attribute into the iframe tag. 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."}],"title":"Cryptocurrency Prijsvergelijking Widget <= 1.0 - Authenticated (Contributor+) Stored Cross-Site Scripting via 'width' Shortcode Attribute","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/058e47cd-55c8-48b3-8aa6-ef299886061d?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/cryptocurrency-prijsvergelijking-widget/trunk/functions.php#L157"},{"url":"https://plugins.trac.wordpress.org/browser/cryptocurrency-prijsvergelijking-widget/trunk/functions.php#L138"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","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":"nail majdeddine"}],"timeline":[{"time":"2026-05-26T17:21:11.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-05-27T10:18:12.691706Z","id":"CVE-2026-8698","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-05-27T10:40:15.946Z"}}]}}
