CVE-2026-751346.4 MED—
———SEOWriting plugin for WordPress through 1.12.5 contains a stored cross-site scripting vulnerability that allows authenticated contributors to inject malicious JavaScript by exploiting an overly permissive KSES allowlist that explicitly permits the onload event handler on iframe elements. Attackers can store crafted JavaScript payloads in post content that execute when the affected post is viewed or previewed by higher-privileged users, potentially leading to privilege escalation or account compromise.17hCVE-2026-846775.4 MED—
———Jenkins update-center2 3.18.3 and earlier does not escape plugin-provided values (plugin names, descriptions, and version metadata) on plugin download index pages, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers able to provide a plugin for hosting.20hCVE-2026-846738.8 HIG—
———Jenkins Customizable Header Plugin 295.v2544b_ca_19b_97 and earlier allows overwriting the plugin's appearance configuration through Stapler data binding, allowing attackers to configure a custom SVG icon containing inline JavaScript, resulting in a stored cross-site scripting (XSS) vulnerability.20hCVE-2026-846658.0 HIG—
———Jenkins SonarQube Scanner Plugin 2.18.3 and earlier does not limit URL schemes for the dashboard links it creates based on SonarQube scanner results, allowing the `javascript:` scheme, resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers with Item/Configure permission.19hCVE-2026-846488.8 HIG—
———In Jenkins 2.579 and earlier, LTS 2.568.2 and earlier, the system log viewer does not escape log record metadata (source, level, and timestamp) resulting in a stored cross-site scripting (XSS) vulnerability exploitable by attackers in control of agent processes.19hCVE-2026-835476.8 MED—
———The Xpro Addons WordPress plugin before 1.7.4 does not properly escape some of its widgets' settings before outputting them within HTML attributes, which could allow users with the Contributor role and above to perform Stored Cross-Site Scripting attacks.22h
