CVE-2026-82367 Aug 30, 18:17 LOW PATCH Monitor

Cross-session record leakage in ash_graphql's subscription batcher allows one subscriber's resolved GraphQL records to be delivered to a different subscriber's topic, potentially crossing tenant and actor boundaries. Versions 1.4.0 through 1.10.x are affected when the Batcher process falls back to inline `:backpressure_sync` or `:noproc` execution paths and a subscription resolver triggers a nested synchronous Ash notification in the same caller process. No public exploit has been identified at time of analysis, and a vendor-released patch is available in version 1.11.0.

CVE-2026-71850 Aug 07, 18:41 npm MEDIUM POC PATCH GHSA This Month

Cross-user HTML disclosure in Hono's server-side rendering affects all applications using hono/jsx with memo()-wrapped components that read request-scoped context. On a warm server instance, when two requests share comparator-equal props, the memoized render from the first request is served to the second user verbatim - bypassing per-request context isolation for values obtained via createContext()/useContext(), useRequestContext(), or getContext(). This can leak another user's profile data, CSRF tokens embedded in HTML, or role-gated content. No public exploit or CISA KEV listing exists at time of analysis; the vendor released a confirmed fix in v4.12.34.

CVE-2026-16326 Jul 29, 18:40 CRITICAL PATCH Act Now

Cross-session token leakage in HashiCorp consul-mcp-server 0.1.0 through 0.1.3 allows one client's Consul authentication token to bleed into requests issued by other clients when the server runs in stateless mode, effectively enabling an attacker to act against Consul with a victim's credentials. HashiCorp rated this CVSS 10.0 (scope-changed) because the borrowed token grants the attacker the victim's full Consul read/write authority across a trust boundary. There is no public exploit identified at time of analysis, and it is not listed in CISA KEV; the fix is consul-mcp-server 0.1.4.

Credential reuse in Terraform MCP Server allows cross-tenant token leakage, enabling unauthorized tool execution on behalf of other users. The vulnerability affects versions prior to 1.1.0 when the server is run in streamable-HTTP stateless transport mode. No public exploit code is known, but the critical CVSS score and network attack vector indicate high potential risk.

CVE-2026-14621 Jul 04, 08:15 LOW POC PATCH Monitor

Session data exposure in FederatedAI FATE's OSX Broker gRPC component allows an authenticated federated party to manipulate session routing arguments and access data belonging to a different federated session. Affected versions extend through FATE 2.2.0, specifically in the QueuePushReqStreamObserver.initEggroll method within the Java-based OSX Broker. No public exploit confirmed active exploitation (not in CISA KEV), though exploit code has been publicly disclosed via a GitHub issue, and the CVSS 4.0 score of 2.3 reflects the high attack complexity and limited confidentiality impact.

Prototype pollution in n8n's Merge node SQL Query mode enables cross-user workflow data interception on multi-user instances. A low-privileged authenticated user can inject JavaScript prototype mutations into a shared, cached sandbox context; because that sandbox is reused across all workflow executions on the instance, the mutations persist into subsequent Merge SQL executions belonging to other users or projects, exposing their workflow data. Vendor-released patches are available in versions 2.25.7 and 2.26.2; no public exploit code or CISA KEV listing has been identified at time of analysis.

Fleet device management software versions prior to 4.81.1 allow malicious enrolled Windows devices to access Mobile Device Management (MDM) commands intended for other devices, potentially disclosing sensitive configuration data including WiFi credentials, VPN secrets, and certificate payloads across the entire Windows fleet. The vulnerability stems from improper authorization controls in Windows MDM command processing, affecting any organization using Fleet for Windows device management. Vendor-released patch: version 4.81.1.

Zabbix Server and Proxy reuse JavaScript (Duktape) execution contexts across script items, JavaScript preprocessing, and webhooks for performance optimization, allowing non-super administrators to leak sensitive data about hosts they lack authorization to access through context variable persistence. The vulnerability enables information disclosure attacks where a regular administrator can access confidential monitoring data from restricted hosts by exploiting shared JavaScript execution environments. A patch has been released that makes built-in Zabbix JavaScript objects read-only, though global variable usage remains unsafe even after remediation.

Email content leakage in Lettermint Node.js SDK versions 1.5.0 and below allows local authenticated users to intercept sensitive email data when a single client instance sends multiple messages, as email properties are not properly cleared between sends. Applications using transactional email flows with reused client instances risk exposing recipient addresses and message content to unintended parties.
