CVE-2026-22872 MEDIUM GHSA This Month

Privilege escalation in Capsule (the Kubernetes multi-tenancy operator) allows authenticated tenant owners to create cluster-scoped resources - including ClusterRole and ValidatingWebhookConfiguration - by embedding them in TenantResource RawItems, bypassing tenant isolation enforced by the platform. The Capsule Controller's default cluster-admin ClusterRoleBinding means it creates whatever resource it is instructed to process, and its attempt to namespace-scope the resource via obj.SetNamespace() is silently ignored by the Kubernetes API for cluster-scoped kinds. A working proof-of-concept is publicly documented in the GHSA advisory; no CISA KEV listing has been issued at time of analysis.

CVE-2026-30963 LOW GHSA Monitor

Namespace hijacking in Capsule (Kubernetes multi-tenancy operator) prior to v0.13.0 allows an authenticated tenant administrator to reassign any namespace to their own tenant by patching it through the namespace/status or namespace/finalize subresource APIs, which bypass Capsule's ValidatingWebhookConfiguration enforcement entirely. The webhook intercepts direct namespace modifications but omits these subresource paths, leaving a gap that an attacker with explicitly delegated RBAC permissions can exploit with a single PATCH request. A complete, working proof-of-concept is publicly available in the GitHub Security Advisory GHSA-2ww6-hf35-mfjm; no CISA KEV listing was identified, indicating no confirmed widespread active exploitation at time of analysis.

CVE-2026-5509 HIGH PATCH This Week

Authenticated command injection in TP-Link Archer BE450 v1 and BE7200 v1 routers lets an admin-level user run arbitrary OS commands with elevated privileges via the web management interface. The flaw stems from improper input validation (CWE-20): crafted input supplied through the management UI is passed to backend system commands without adequate sanitization, enabling full device compromise. There is no public exploit identified at time of analysis, and the CVSS 4.0 vector scopes exploitation to the adjacent network by an already-authenticated administrator.

CVE-2026-48922 HIGH This Week

Arbitrary file write in the Jenkins Credentials Binding Plugin (version 720.v3f6decef43ea_ and earlier) lets users who can supply file or zip-file credentials to a job write files to attacker-chosen paths on the node filesystem, escalating to remote code execution when Jenkins is configured to let a low-privileged user configure such credentials for a job running on the built-in node. The flaw stems from missing file-name sanitization on the file and zip credential types. Rated CVSS 7.5 with high attack complexity (AC:H); no public exploit identified at time of analysis and the issue is not in CISA KEV.

CVE-2026-26147 HIGH PATCH NO ACTION HOSTED Monitor

Information disclosure in Microsoft Azure Compute Gallery permits an authenticated remote attacker to read sensitive data across tenant or resource boundaries due to improper input validation (CWE-20). The scope-changed CVSS 7.7 rating reflects cross-boundary impact, but the exploit maturity is currently unproven (E:U) and no public exploit identified at time of analysis. Microsoft has published an official fix via MSRC.

Remote code execution in Microsoft Azure Virtual Network Gateway allows an authenticated attacker with low privileges to execute arbitrary code across a network boundary due to improper input validation. The CVSS 9.9 score reflects scope-changed impact (S:C) where exploitation can compromise resources beyond the vulnerable component itself, affecting confidentiality, integrity, and availability. No public exploit identified at time of analysis, though the high score and managed-service nature warrant priority attention.

An authentication logic vulnerability in multiple TP-Link range extenders allows an unauthenticated attacker on an adjacent network to manipulate a login parameter and reset the administrator password due to insufficient validation. Successful exploitation allows an attacker to obtain full administrative control of the affected device, potentially impacting on confidentiality, integrity, and availability.

CVE-2026-34207 HIGH This Week

Server-side request forgery in Typebot chatbot builder versions prior to 3.16.0 allows authenticated users to bypass SSRF protections in Webhook and HTTP Request blocks by supplying attacker-controlled hostnames that resolve via DNS to loopback (127.0.0.1), cloud metadata (169.254.169.254), or RFC1918 private addresses. The validation logic only inspected the URL string and literal IP formats without performing DNS resolution, so a benign-looking domain could route the backend HTTP client to internal targets. No public exploit identified at time of analysis, though the GitHub Security Advisory and fix commit are publicly visible.
