Descripción técnica

The Easy Accordion plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'accordionTitleTag' block attribute in versions up to, and including, 3.1.8. This is due to insufficient input sanitization and output escaping in the accordion_header_renderer() function, which emits the attacker-supplied tag name using esc_attr() in an HTML tag-name context instead of tag_escape(). 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.

——0lakeFS is an open-source tool that transforms object storage into a Git-like repositories. Prior to version 1.81.1 of the open source edition and 1.84.0 of the enterprise edition, lakeFS Web UI renders markdown files from repository objects without sanitizing the resulting HTML. A user with write access to any repository branch can commit a `.md` object containing arbitrary HTML/JavaScript. Any other user who opens that object, or who navigates to a repository or directory containing a malicious `README.md`, executes the attacker-supplied script in their own authenticated session. lakeFS fixes the issue in v1.81.1 and lakeFS Enterprise fixes the issue in in v1.84.0. Enterprise customers using older versions can temporarily disable Markdown rendering by adding YAML to their config. No workaround exists for OSS release. Users are advised to upgrade to the latest version for both lakeFS and lakeFS-Enterprise.15h CVE-2026-114254.4 MED

——0Domoticz versions prior to 2026.3 contains a stored cross-site scripting vulnerability in the mobile dashboard that allows authenticated attackers to inject arbitrary HTML and JavaScript by updating Text or Alert subtype device values through the API. The mobile dashboard renders device data via ng-bind-html with only an nl2br() transform that performs no HTML escaping, allowing attackers to store malicious payloads that execute in any administrator's browser upon viewing the mobile dashboard, enabling session cookie theft and account takeover.17h CVE-2026-622935.0 MED

——0HAPI FHIR is a complete implementation of the HL7 FHIR standard for healthcare interoperability in Java. Prior to 6.9.11, the hidden scan command concatenates attacker-controlled Implementation Guide titles, profile titles, and source references into scan.html without escaping in Scanner.java. As a result, a user who scans an attacker-supplied IG/profile and then opens or publishes the generated local/CI HTML report can trigger stored cross-site scripting, executing attacker-controlled JavaScript in the report's browser context. This issue is fixed in version 6.9.11.17h CVE-2026-192303.5 BAJ

——0WordPress is vulnerable to a pre-auth reflected XSS vulnerability on the login screen. Via a specially crafted malicious third-party website hosted by an attacker, it is possible for this to be escalated to an RCE vulnerability with conditions outside of the attackers control. This requires successful social engineering of and explicit interaction by the target victim. This issue affects all versions of WordPress. Version 7.0.3 has been released, containing a fix for the vulnerability, and as a courtesy to users on older branches the fix has been backported to all branches back to 4.7.
