Technical description

django-helpdesk before 2.3.3 contains a stored cross-site scripting vulnerability that allows unauthenticated attackers to inject arbitrary JavaScript by submitting HTML-formatted email messages or uploading .html/.htm file attachments through public ticket submission channels. Attackers can exploit the lack of sanitization and Content-Disposition headers at the attachment-serving layer to execute malicious scripts in the browser session of authenticated staff members who open the attachment while triaging tickets.

———A flaw was found in migration-planner. Insufficient validation of the `AgentStatusUpdate.CredentialUrl` field allows an authenticated attacker to store a malicious `javascript:` URL. When a victim views this URL in the Hybrid Cloud Console, it can lead to Cross-Site Scripting (XSS), enabling script execution in the victim's session and potentially disclosing sensitive information.5h CVE-2026-728325.4 MED

———Grav versions from 1.5.2 through 2.0.12 contain a stored cross-site scripting vulnerability in the Security::detectXss() function (system/src/Grav/Common/Security.php). The event-handler scan is anchored at `<` and uses `[^>]*?`, which cannot cross the first literal `>`; when a `>` appears inside a quoted attribute value the browser keeps the tag open and parses a subsequent event handler (e.g. onerror), so the detector and browser disagree. A page editor without admin.super privileges can save page content such as `<img src=x title=">" onerror=alert(document.domain)>`, which is accepted, stored, and executed in the site origin when any visitor (including unauthenticated users) views the page. Fixed in 2.0.13.5h CVE-2026-728215.4 MED

Attackers with form authoring permissions can inject HTML and script payloads in option labels that execute in the browsers of visitors and administrators viewing the form.8h CVE-2026-197947.2 HIG

———The WP-Stats plugin for WordPress is vulnerable to Stored Cross-Site Scripting in all versions up to, and including, 2.56 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.9h CVE-2026-142906.8 MED

———The Embed Google Photos album WordPress plugin through 2.2.1 does not escape a shortcode attribute value before outputting it inside an HTML attribute, allowing users with the Contributor role or above to inject arbitrary JavaScript that executes in the browser of any user, including administrators, who views the affected post.4h CVE-2026-181097.2 HIG

———The W3 Total Cache plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Comment Author Name in all versions up to, and including, 2.10.3 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This vulnerability is only exploitable when the Lazy Load Images feature of W3 Total Cache is enabled, as the unsafe re-emission occurs exclusively within the LazyLoad mutator's img tag rewriting step.9h
