This is due to insufficient input sanitization and output escaping on user-supplied shortcode attributes in the GBMI_Calc_Widget::widget() function. Shortcode attributes are extracted directly into local variables via @extract($args) and then echoed unescaped into an HTML style attribute (height/width) and HTML body context (title), allowing attribute-breakout payloads. 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":"Global Body Mass Index Calculator <= 1.2 - Authenticated (Contributor+) Stored Cross-Site Scripting via Shortcode Attributes","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/06804bed-17c5-413c-a31b-f6f039015e26?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/global-body-mass-index-calculator/tags/1.2/gbmicalc.php#L335"},{"url":"https://plugins.trac.wordpress.org/browser/global-body-mass-index-calculator/tags/1.2/gbmicalc.php#L134"},{"url":"https://plugins.trac.wordpress.org/browser/global-body-mass-index-calculator/tags/1.2/gbmicalc.php#L345"},{"url":"https://plugins.trac.wordpress.org/browser/global-body-mass-index-calculator/tags/1.2/gbmicalc.php#L476"}],"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":"Muhammad Yudha - DJ"}],"timeline":[{"time":"2026-06-08T15:07:06.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-09T14:12:23.710404Z","id":"CVE-2026-8883","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":"2026-06-09T14:12:35.934Z"}}]}}
