CVE-2026-69151——
———Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 20.3.27, 21.2.19, and 22.0.1, the Angular compiler i18n pipeline permits i18n-onerror and other i18n-on event-handler attributes, allowing a lower-trust translation file to replace a static handler with executable JavaScript. This issue is fixed in versions 20.3.27, 21.2.19, and 22.0.1.6hCVE-2026-69149——
———Angular is a development platform for building mobile and desktop web applications using TypeScript/JavaScript and other languages. Prior to 20.3.27, 21.2.19, and 22.0.7, a Cross-Site Scripting (XSS) vulnerability exists in @angular/platform-server's DOM emulation dependency (domino) when serializing the content of fallback raw-content elements (<iframe>, <noembed>, <noframes>, and <noscript>). This issue is fixed in versions 20.3.27, 21.2.19, and 22.0.7.6hCVE-2026-676124.8 MED—
———OpenEMR through 8.2.0 contains a stored cross-site scripting vulnerability in the patient portal template system that allows authenticated administrators to inject arbitrary HTML and JavaScript by storing malicious payloads through the template save mode, which only filters literal PHP open tags. Attackers can exploit the lack of output encoding at the template retrieval endpoint combined with missing HttpOnly cookie attributes to exfiltrate session tokens via document.cookie access, enabling full session hijacking of any admin, clinician, or portal patient who views a poisoned template.7hCVE-2026-18243——
———Certain HP DesignJet products may be potentially vulnerable to cross-site scripting (XSS), which may allow unauthenticated HTTP requests to view print job previews.6hCVE-2026-690926.5 MED—
———Admidio versions before 5.0.11 contain a reflected cross-site scripting vulnerability in the SSO/SAML endpoint that echoes unencoded exception messages to the HTTP response. Unauthenticated attackers can inject arbitrary JavaScript through SAML Issuer elements or LightSaml library parameters to execute code in users' browsers and hijack sessions.9hCVE-2026-69075——
——0FlowIntel is affected by a stored cross-site scripting vulnerability through multiple user-controlled or administrator-controlled fields.
Persisted values—including case titles, ticket identifiers, recurring-case information, user profile attributes, organisation names, and role names—were rendered inside DOM elements subsequently compiled by Vue. Although normal HTML escaping could neutralize direct HTML markup, it did not prevent an attacker from injecting Vue interpolation expressions using the configured [[ ... ]] delimiters.
An authenticated attacker able to modify one of the affected fields could store a malicious Vue expression. When another user viewed an affected case, report, profile, recurring-case page, or navigation component, Vue could evaluate the injected expression in the context of the FlowIntel application.
Successful exploitation could allow arbitrary JavaScript execution in the victim’s browser under the FlowIntel origin. This could expose information available to the victim, perform actions using the victim’s authenticated session, or modify application data within the victim’s privileges.
The patch introduces a dedicated vue_escape filter that escapes HTML-sensitive characters and breaks Vue interpolation delimiters before the values are rendered. The filter is applied to the affected case, account, organisation, role, configuration, and navigation fields.12h
