Directus GraphQL endpoints fail to deduplicate resolver invocations within single requests, allowing authenticated users to exploit GraphQL aliasing for denial-of-service attacks. An attacker with minimal read-only permissions can repeat expensive relational queries using multiple aliases in a single request, forcing concurrent execution of numerous complex database queries that exhaust connection pools and server resources, potentially degrading or crashing the service. No public exploit code has been identified, and this vulnerability requires prior authentication to the Directus instance.

Denial of service in Avahi prior to version 0.9-rc4 allows local unprivileged users to crash avahi-daemon by sending a D-Bus method call with conflicting publish flags. The vulnerability requires local access and low privileges but causes immediate service unavailability. No public exploit code or active exploitation has been confirmed; however, the attack is trivial to execute given the low complexity barrier.

Denial of service in vLLM's VideoMediaIO.load_base64() method allows authenticated remote attackers to crash the server via memory exhaustion by sending API requests with thousands of comma-separated base64-encoded JPEG frames. The vulnerability bypasses the default 32-frame limit enforced in other video loading code paths, allowing attackers to decode gigabytes of image data into memory (e.g., 5000 frames ≈ 4.6 GB for 640x480 RGB) with a small compressed payload. CVSS 6.5 (network-accessible, low complexity, requires authentication, high availability impact); no public exploit code identified at time of analysis.

Denial of service in @nyariv/sandboxjs through unbounded recursion in the parser allows remote attackers to crash Node.js processes by submitting deeply nested expressions (approximately 2000 nested parentheses or brackets), triggering a RangeError that terminates the application. All public API methods (Sandbox.parse, Sandbox.compile, Sandbox.compileAsync, Sandbox.compileExpression, Sandbox.compileExpressionAsync) are vulnerable with no input validation or depth limiting. A proof-of-concept demonstrating the crash exists; no public active exploitation has been reported at the time of analysis.

Memory exhaustion denial of service in jupyterhub-litauthenticator 1.6.2 and earlier allows unauthenticated remote attackers to crash the LTI 1.1 validator by submitting repeated requests with unique OAuth nonces. The vulnerability exists because nonces are stored in an unbounded class-level dictionary before signature validation occurs, enabling an attacker with knowledge of a valid consumer key to gradually exhaust server memory without authentication. EPSS score of 5.9 (medium-high) reflects the network attack vector and practical exploitability, though the requirement to know a valid consumer key and achieve high authentication complexity moderates real-world risk.

Hirschmann HiSecOS devices versions prior to 05.3.03 contain a buffer overflow vulnerability in the HTTPS login interface when RADIUS authentication is enabled that allows remote attackers to crash. Rated critical severity (CVSS 9.3), this vulnerability is remotely exploitable, no authentication required, low attack complexity. No vendor patch available.

Denial of service in rust-rpm-sequoia allows local attackers to crash RPM signature verification by submitting specially crafted RPM files that trigger unhandled errors in OpenPGP parsing, preventing legitimate package management operations. CVSS 4.0 (low severity), local attack vector, non-authenticating. No public exploit code or active exploitation confirmed.
