All libmodsecurity3 versions before 3.0.15 are affected across Apache, IIS, and Nginx deployments. OWASP confirmed the vulnerability via GitHub security advisory GHSA-qrjc-3jpc-3h2g and released patch version 3.0.15 addressing this buffer overflow (CWE-125: Out-of-bounds Read).

Unauthenticated remote denial-of-service in Phoenix Framework 1.7.0-1.7.21 and 1.8.0-1.8.5 allows attackers to crash Elixir BEAM nodes by sending multi-megabyte HTTP requests filled with newlines to the long-poll transport endpoint. A 1 MB payload of newline characters triggers allocation of approximately one million empty list elements, exhausting scheduler and memory resources. Session token required to trigger the vulnerability is obtainable via unauthenticated GET request, making exploitation trivial. Vendor-released patches (1.7.22, 1.8.6) enforce client-side batching limits. CVSS 8.7 (high availability impact) confirmed; no public exploit or CISA KEV listing identified at time of analysis.

Uncontrolled resource consumption in Apache HTTP Server's mod_md module allows remote unauthenticated attackers to exhaust server resources via malformed OCSP response data, affecting versions 2.4.30 through 2.4.66. The vulnerability enables attackers to achieve confidentiality, integrity, and availability impacts with low complexity exploitation over the network. No active exploitation confirmed (not in CISA KEV), but the network-accessible attack surface and lack of authentication requirement make this a credible threat requiring prompt patching to version 2.4.67.

Remote attackers can crash OpenClaw 2026.4.9 by sending oversized WebSocket frames to the voice-call realtime webhook path, causing complete service unavailability. The vulnerability requires no authentication and affects deployments that expose the WebSocket endpoint externally. Vendor patch released in version 2026.4.10 with commit afadb7dae6738819ad9c7d2597ace0516957d20e. No active exploitation confirmed (not in CISA KEV), but public advisory with commit details provides exploitation blueprint.

Network-accessible denial-of-service in HashiCorp Boundary workers allows unauthenticated remote attackers to block legitimate worker connections by manipulating TLS handshake timing during node enrollment. Attackers can connect to the worker authentication listener and intentionally delay or withhold client certificates, causing connection handlers to block and preventing legitimate workers from enrolling or routing traffic. Both Community Edition and Enterprise versions prior to 0.21.3, 0.20.3, and 0.19.5 are vulnerable. EPSS data not provided; no CISA KEV listing indicating limited observed exploitation. Vendor-confirmed vulnerability with patches released across three active release branches.

Authenticated attackers can escalate privileges to administrator in Pelican Web User Interface versions 7.21 through 7.24 by manipulating database records before legitimate admin users log in. This vulnerability was discovered by a Claude coding agent on April 2, 2026, and affects servers with Server.UIAdminUsers or Server.AdminGroups configured where designated admins have not previously authenticated. No public exploit code exists, and Pelican Command Line reports no confirmed exploitation in OSDF-managed services. Vendor patches are available across all affected minor release series (>=v7.21.5, >=v7.22.3, >=v7.23.3, >=v7.24.2), with fix commit 7f73b9c3e677 addressing CWE-863 (Incorrect Authorization).

Memory exhaustion crashes Argo Workflows server via unauthenticated multi-gigabyte webhook requests to the publicly accessible `/api/v1/events/` endpoint. The Webhook Interceptor's `io.ReadAll` call allocates unbounded memory before signature verification, enabling remote attackers to trigger out-of-memory (OOM) conditions without authentication or credentials. Vendor-released patches enforce a 2MB body size limit via `io.LimitReader`. Publicly available exploit code exists (conceptual proof-of-concept published in GitHub security advisory GHSA-jcc8-g2q4-9fxq). No active exploitation confirmed by CISA KEV at time of analysis, but the low attack complexity (CVSS AV:N/AC:L/PR:N) and public PoC create immediate risk for internet-exposed Argo Workflows deployments.

Missing authorization checks in Argo Workflows v4.0.0-4.0.4 allow any authenticated user-even those with fake Bearer tokens-to create, read, update, and delete Kubernetes ConfigMaps containing workflow synchronization limits. The ConfigMap-backed sync provider (server/sync/sync_cm.go) completely omits auth.CanI permission validation on all four CRUD endpoints. Publicly available exploit code exists (detailed PoC in advisory). CVSS 8.5 reflects network-accessible authentication bypass enabling high integrity/availability impact through denial-of-service and arbitrary ConfigMap manipulation. Patch released in version 4.0.5 adding checkConfigMapPermission() calls to validate Kubernetes RBAC before operations.

Denial of service in Incus prior to version 7.0.0 allows authenticated users to crash the Incus daemon by importing a maliciously crafted backup archive with physical snapshot directories but tampered metadata arrays. The vulnerability stems from an incorrect bounds check (len(slice) >= i-1 instead of len(slice) > i) in the backup restore and migration code paths, enabling out-of-bounds array access that triggers a runtime panic. Repeated exploitation keeps the Incus service offline, confirmed by a publicly available proof-of-concept.

Unbounded cache growth in @fastify/accepts-serializer versions ≤6.0.3 allows remote unauthenticated attackers to exhaust Node.js heap memory by sending numerous distinct Accept header variants, crashing the application. The plugin caches serializer selections keyed by Accept header without size limits, enabling trivial memory exhaustion attacks against any exposed Fastify endpoint. Fix available in version 6.0.4, which implements an LRU cache with 100-entry default limit. No public exploit code identified at time of analysis, but attack is straightforward to execute with basic HTTP tools.

Denial-of-service condition in Conditional Fields for Contact Form 7 WordPress plugin allows remote unauthenticated attackers to crash PHP processes by injecting arbitrarily large iteration values through REST API parameters. The Wpcf7cfMailParser class processes user-supplied POST data without validation, enabling attackers to trigger unbounded loops with multiple regex operations that exhaust server memory. Affects all versions through 2.6.7 with vendor patch now available. EPSS data not provided, but the network-accessible unauthenticated attack vector (AV:N/PR:N) combined with low complexity (AC:L) indicates straightforward exploitation potential against publicly accessible WordPress sites running this plugin.

Heap buffer overflow in BusyBox udhcpc6 (DHCPv6 client) allows network-adjacent attackers to achieve remote code execution or denial of service on embedded systems. The vulnerability stems from incorrect heap buffer allocation in option_to_env() when parsing D6_OPT_DNS_SERVERS options in DHCPv6 responses. Particularly dangerous on embedded devices lacking heap hardening protections. Fixed in commit 42202bf. No active exploitation confirmed (not in CISA KEV), but publicly available proof-of-concept from VulnCheck disclosure increases real-world risk for IoT and embedded deployments.

Memory exhaustion in Prometheus remote read endpoint allows unauthenticated attackers to crash the monitoring server via maliciously crafted snappy-compressed payloads. The /api/v1/read endpoint in versions prior to 3.5.3 and 3.11.3 accepts compressed request bodies without validating the declared decoded length, enabling a 5-byte payload claiming 256 MiB decoded size to trigger massive heap allocations. Concurrent requests can exhaust memory and crash the Prometheus process. EPSS data not provided; no evidence of active exploitation (not in CISA KEV). Vendor-released patches available in versions 3.5.3 and 3.11.3.

Remote denial of service in the Postfix mail transfer agent (before 3.8.16, 3.9.x before 3.9.10, and 3.10.x before 3.10.9) lets attackers crash the process through a malformed enhanced status code that ends immediately after the third numeric component with no trailing text, triggering a buffer over-read. The flaw affects availability only - no data exposure or code execution - and has no public exploit identified at time of analysis. EPSS is very low (0.04%, 11th percentile) and CISA SSVC rates exploitation as none and non-automatable, consistent with a crash-only bug.

Nil-pointer dereference in Incus daemon's custom volume backup import logic allows authenticated users to crash the service by supplying a malformed backup archive containing null entries in the volume_snapshots array, enabling repeated denial of service attacks. The vulnerability exists in the CreateCustomVolumeFromBackup function which fails to validate snapshot pointers before dereferencing them during import operations. CVSS 6.5 (authenticated network access, high availability impact); no public exploit code or active exploitation reported at analysis time, but proof-of-concept demonstration included in advisory.

Nil-pointer dereference in Incus daemon's storage bucket import logic allows authenticated users to crash the daemon by submitting a malformed bucket backup archive with a missing config section in index.yaml, enabling denial of service through repeated exploitation. The vulnerability affects Incus versions prior to 7.0.0 and requires valid storage bucket feature access but no special privileges beyond authenticated user status.

Remote denial of service in Apache OpenNLP versions before 2.5.9 and 3.0.0-M3 allows unauthenticated attackers to crash JVM processes by uploading malicious .bin model files that trigger OutOfMemoryError through unbounded array allocation. Exploitation requires no authentication (AV:N/AC:L/PR:N) and affects any code path deserializing binary model files from untrusted sources. EPSS score of 0.02% (5th percentile) suggests low widespread exploitation risk, and no active exploitation or public POC has been identified at time of analysis. Vendor-released patches are available with default safeguards limiting count fields to 10 million entries.

Remote attackers can crash Apache HTTP Server 2.4.66 and earlier by sending malicious requests that trigger a NULL pointer dereference in mod_dav_lock, causing denial of service. The vulnerability affects only servers with mod_dav_lock enabled, a legacy module whose primary use-case (Apache Subversion < 1.2.0) is obsolete in modern deployments. CISA SSVC indicates no active exploitation, but the attack is automatable against susceptible configurations. CVSS 7.5 (High) reflects network-accessible, unauthenticated denial of service, though real-world impact is limited to the small subset of servers still running mod_dav_lock.

Denial of Service in FRRouting 10.0 through 10.6 allows remote unauthenticated attackers to crash the BGP daemon via a malformed BGP UPDATE message exploiting an integer underflow in next-hop capability processing. Upstream fix available in commit 693a2e0 but released patched version not independently confirmed. No public exploit identified at time of analysis, with EPSS score not provided suggesting low observed exploitation activity.

Remote attackers can crash GoBGP v4.3.0 by sending a malformed BGP UPDATE message that triggers an out-of-bounds read in IPv6 extended community parsing. The flaw allows unauthenticated denial of service against default configurations with no authentication required (CVSS AV:N/AC:L/PR:N/UI:N). No public exploit identified at time of analysis, and EPSS score of 0.02% (4th percentile) indicates very low observed exploitation probability. Upstream fixes available via GitHub commits 362cce3e and 9ce8936.

Memory exhaustion in Bandit WebSocket server (versions 0.5.9 through 1.10.x) allows unauthenticated remote attackers to crash BEAM nodes via compression bombs when permessage-deflate is enabled. The inflate/2 function decompresses WebSocket frames without output-size limits, enabling attackers to send tiny compressed payloads (~1024:1 ratio) that expand to gigabyte-scale heap allocations. Vendor-released patch available (version 1.11.0). EPSS data not available; no public exploit identified at time of analysis. Exploitation requires non-default configuration (both server-level compress and per-upgrade compress: true options enabled), making stock Phoenix/LiveView applications unaffected.

Memory exhaustion in Bandit WebSocket server (versions 0.5.0 through 1.10.x) allows unauthenticated remote attackers to trigger denial of service by sending unbounded WebSocket continuation frames without setting the fin flag. The fragment reassembly logic accumulates payloads without checking cumulative message size, bypassing the max_frame_size limit which only applies to individual frames. Applications using Phoenix Channels or LiveView over Bandit expose this attack surface on any WebSocket endpoint. Patch available in version 1.11.0 introduces max_fragmented_message_size parameter (default 8MB). No public exploit code identified at time of analysis, but trivial to reproduce with standard WebSocket libraries.

Remote unauthenticated denial of service crashes Vanetza V2X v26.02 receivers via malformed GeoNetworking packets containing invalid ECC points. Uncaught OpenSSL exceptions from elliptic curve point validation (invalid compressed points, points not on curve) in the security layer escape through the Router::indicate() call chain, triggering std::terminate and process termination. No public exploit identified at time of analysis, though EPSS risk assessment unavailable. Attack requires only network access to the V2X receiver endpoint with no authentication or user interaction (CVSS AV:N/AC:L/PR:N/UI:N), making this a significant operational risk for deployed V2X infrastructure relying on continuous availability for vehicle safety communications.

Use-after-free in Imagination Graphics DDK GPU GLES user-space library allows authenticated remote attackers to crash the GPU render process via crafted WebGPU content. CVSS 8.1 (High) with network vector and low complexity. On platforms where the GPU process runs with elevated system privileges, successful exploitation could enable system-level compromise beyond the initial crash. EPSS and KEV data not provided; SSVC framework indicates no confirmed exploitation, non-automatable attack, but total technical impact. Vendor patches available across affected DDK versions 1.18, 23.2, 24.1-24.2, and 25.1-25.3.

Remote authenticated attackers can execute code or cause persistent denial-of-service in Imagination Technologies Graphics DDK by triggering a use-after-free in the GPU GLES render process via specially crafted WebGPU content. On platforms where the GPU driver runs with elevated system privileges, successful exploitation enables device-level compromise beyond the browser sandbox. EPSS data not available, no CISA KEV listing identified, no public POC confirmed. SSVC framework indicates no active exploitation and non-automatable attack requiring authenticated interaction.

Heap-based buffer overflow in hashcat 7.1.2 enables remote code execution or denial of service through maliciously crafted PKZIP hash files. Attackers can exploit inadequate input validation in the hex_to_binary function affecting PKZIP hash parser modules (17200, 17210, 17220, 17225, 17230) to overflow fixed-size buffers with arbitrary hex data. CVSS 9.8 reflects network-accessible attack vector requiring no authentication or user interaction, though real-world exploitation requires victim to process attacker-supplied hash files. EPSS data not available; no CISA KEV listing indicates no confirmed widespread exploitation. Public proof-of-concept exists (GitHub Gist), elevating exploitation risk for environments processing untrusted hash files.

Heap-based buffer overflow in hashcat 7.1.2's Kerberos hash parser enables remote code execution without authentication. Attacker supplies a maliciously crafted Kerberos hash file with manipulated delimiter positions to overflow the fixed-size account_info buffer during memcpy operations in module_hash_decode. The vulnerability affects multiple Kerberos-related hashcat modules due to missing upper-bound validation on account_info_len before memory copy. CVSS 9.8 with network attack vector, but real-world exploitation requires user processing the malicious file. EPSS data not available; no active exploitation confirmed in CISA KEV at time of analysis.

Stack-based buffer overflow in hashcat 7.1.2's rule processing functions enables remote code execution when processing password candidates of 128+ characters. The vulnerability stems from inadequate bounds checking in mangle_to_hex_lower() and mangle_to_hex_upper() functions that fail to account for 2x memory expansion during byte-to-hex conversion. CVSS 9.8 (critical) with network attack vector and no authentication required. Public proof-of-concept code available via GitHub gist. No CISA KEV listing suggests targeted rather than widespread exploitation despite theoretical network exploitability.

Use-after-free condition in Linux kernel writeback subsystem allows local authenticated attackers to potentially execute arbitrary code, escalate privileges, or trigger kernel crashes. The vulnerability affects Linux kernel versions 6.18.x through 7.1-rc1 and arises from improper synchronization between work queue processing and memory deallocation in inode_switch_wbs_work_fn(). Vendor patches are available across stable kernel branches (6.18.25, 7.0.2, 7.1-rc1) with low EPSS score (0.02%) indicating minimal observed exploitation activity, though the CVSS 7.8 score reflects significant impact if successfully exploited by authenticated local users.

Use-after-free in Linux kernel macb driver allows local authenticated attackers to cause denial of service or potentially escalate privileges during module removal. The vulnerability occurs in the PCI glue driver when platform_device_unregister() triggers a runtime resume callback that attempts to access already-freed clock structures. EPSS score is low (0.02%) with no evidence of active exploitation. Vendor patches are available across multiple stable kernel branches (5.10.253, 5.15.203, 6.1.168, 6.6.134, 6.12.81, 6.18.22, 6.19.12, and mainline 7.0).

Integer overflow in Linux kernel io_uring subsystem allows local authenticated users to trigger slab-out-of-bounds memory reads and denial of service. The vulnerability stems from improper type casting of user-supplied length values in network bundled receive/send operations, where values exceeding INT_MAX cause negative overflow leading to infinite loops and out-of-bounds array access. EPSS score of 0.02% (5th percentile) indicates low probability of widespread exploitation. Vendor patches available for affected stable kernel branches (6.12.81, 6.18.22, 6.19.12, 7.0), making this a straightforward patching priority for systems running vulnerable versions with io_uring enabled.

Missing CRYPTO_ALG_ASYNC flag in Linux kernel's Tegra crypto driver causes the crypto API to incorrectly select asynchronous algorithms for synchronous-only requests, resulting in system crashes. This affects Tegra-based Linux systems (typically NVIDIA Jetson devices) running kernel versions 6.10 through early 7.0 development branches. Vendor patches are available across stable branches (6.12.81, 6.18.22, 6.19.12, 7.0). EPSS score of 0.02% (5th percentile) indicates minimal observed exploitation probability, and no active exploitation or public POC has been identified. The CVSS vector (AV:N/AC:L/PR:L/UI:N) suggests network-based exploitation requiring authenticated access, though this conflicts with the technical nature of a local driver configuration bug.

Algorithmic complexity denial of service in Apache Neethi allows remote unauthenticated attackers to exhaust JVM heap memory via malicious WS-Policy documents. Specially crafted policy documents trigger exponential Cartesian cross-product expansion during normalization, generating unbounded policy alternatives that consume all available memory. Apache has released version 3.2.2 with normalization limits to prevent exploitation. EPSS data not available; no CISA KEV listing identified at time of analysis.
