python-liquid FileSystemLoader Absolute Path Escape Vulnerability

The FileSystemLoader in python-liquid versions before 2.2.0 allows malicious template authors to read arbitrary files outside the search paths via the `{% include %}` and `{% render %}` tags by using absolute paths; this is resolved in version 2.2.0 by checking for absolute paths in the `resolve_path()` method.

urllib3 Sensitive Header Leak in Low-Level Redirects (CVE-2026-44431)

Sensitive headers (`Authorization`, `Cookie`, and `Proxy-Authorization`) are forwarded across origins in proxied low-level redirects when using `HTTPConnection.urlopen()` instances created via `ProxyManager.connection_from_url()` in urllib3 versions before 2.7.0, potentially exposing credentials to unintended third parties; upgrade to version 2.7.0 or later to remediate this issue.

GuardDog SSRF and GH_TOKEN Exfiltration via Blind URL Rewrite (CVE-2026-44971)

GuardDog versions 1.0.0 through 2.9.0 are vulnerable to Server-Side Request Forgery (SSRF) and potential `GH_TOKEN` exfiltration due to a blind URL rewrite in remote project scanning; an attacker can influence the scanned repository URL to trigger SSRF and capture the `GH_TOKEN` used by GuardDog.

OpenTelemetry Prometheus Exporter Denial-of-Service via Malformed HTTP Request (CVE-2026-44902)

A malformed HTTP request can crash any Node.js process running the OpenTelemetry JS Prometheus exporter. The metrics endpoint has no error handling around URL parsing, so a request with an invalid URI causes an uncaught `TypeError` that terminates the process, leading to a denial of service. Update `@opentelemetry/exporter-prometheus` and `@opentelemetry/sdk-node` to version **0.217.0** or later and `@opentelemetry/auto-instrumentations-node` to version **0.75.0** or later to remediate.
