Descripción técnica

The Independent Analytics plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 404 not_found_url tracking parameter in versions up to, and including, 2.15.0. This is due to the get_cell_content() function applying urldecode() after esc_url() when rendering the URL column for 404 entries — a sequence that allows percent-encoded HTML to pass URL validation and then be reconstructed as raw markup, which wp_kses_post() does not strip because it retains img elements and data-* attributes, and because the public REST endpoint /iawp/search accepts unauthenticated requests as long as they carry a signature that is itself embedded in public page HTML. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.

—

———A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) could allow an authenticated, remote attacker to conduct a cross-site scripting (XSS) attack against a user of the interface. This vulnerability is due to insufficient validation of user input. An attacker could exploit this vulnerability by persuading a user of an affected interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the browser of the targeted user or access sensitive, browser-based information.5h CVE-2026-91959.3 CRÍ

———A cross-site scripting vulnerability in the Query Console of Progress MarkLogic Server before 11.3.6 and 12.0.3 allows a remote attacker who lures an authenticated administrator to a crafted URL to execute arbitrary JavaScript in the administrator's browser session, capture credentials, and perform privileged actions on the administrator's behalf.6h CVE-2026-705964.3 MED

—

———Ghost is a Node.js content management system. From 4.9.0 until 6.54.1, an input validation issue allowed any staff user to create a post with content in feature_image_caption that could be used to hijack another staff user's Ghost Admin session, resulting in privilege escalation. This issue is fixed in 6.54.1.6h CVE-2026-539926.1 MED

—

———ProjectSend r2029 contains a reflected cross-site scripting vulnerability in thumbnails-regenerate.php that allows remote attackers to inject arbitrary HTML and JavaScript by supplying unsanitized values in the start_date and end_date GET parameters, which are echoed unescaped into HTML attribute values. Attackers can craft a malicious URL that, when followed by an authenticated victim with edit_settings permissions, executes injected scripts in the application origin to steal session cookies or perform unauthorized actions including user management, file management, and application settings changes.6h CVE-2026-712858.1 ALT

—

———Uptime Kuma's Matomo analytics integration (server/analytics/matomo-analytics.js) injects the admin-configurable Matomo `siteId` value as a bare, unquoted JavaScript expression inside a <script> block rendered on every public status page: `_paq.push(['setSiteId', ${escapedSiteIdHTMLAttribute}]);`. The escaping pipeline used (jsesc with isScriptContext:true, then html-escaper.escape()) does not escape the characters `]`, `)`, `;`, `(`, which are sufficient to break out of the array/push expression context. A siteId value such as `1]);alert(document.cookie)//`, once saved by an editor/admin, executes arbitrary JavaScript for every unauthenticated visitor of the public /status/<slug> page, enabling session-cookie theft and full page takeover.6h CVE-2026-712755.4 MED

———OpenBK7231T's http_fn_ota_exec() (src/httpserver/http_fns.c) reflects the `host` query parameter directly into an HTML response via hprintf255(request, "<h3>OTA requested for %s!</h3>", tmpA) with no HTML encoding, allowing a crafted URL such as /ota_exec?host=<script>alert(1)</script> to execute JavaScript in an authenticated admin's browser when they click a malicious link.6h
