CVE-2026-66919

Pivotick contains a cross-site scripting vulnerability in the inspect and edit node modals. Node labels and descriptions originating from graph data were interpolated directly into HTML used to construct the modal headers. An attacker able to supply or modify graph data could insert a malicious...

CVE-2026-66919

Pivotick exposes a DOM-based XSS in the node inspect/edit modals. Node labels/descriptions sourced from graph data were interpolated into modal HTML, enabling injected HTML/JS to run in the victim’s origin when a node is opened. The issue is mitigated by removing graph data embedding in HTML and ...

CVE-2026-49332

A flaw was found in openshift/oauth-proxy. The proxy sets authenticated identity headers using only dash-variant keys X-Forwarded-User but does not strip underscore-variant keys XForwardedUser from incoming requests. WSGI and PHP frameworks normalize both variants to the same variable, allowing a...

urllib3: urllib3: Information disclosure via cross-origin redirects forwarding sensitive headers

A flaw was found in urllib3, an HTTP client library for Python. When using the low-level API via ProxyManager.connectionfromurl.urlopen with assertsamehost=False, cross-origin redirects can still forward sensitive headers. This could allow a remote attacker to gain unauthorized access to sensitiv...
