CVE-2026-12151 2 Nodejs, Undici 2 Undici, Undici 2026-09-11 7.5 High
Impact: The undici WebSocket client enforces maxPayloadSize on the cumulative byte count of fragments in a message but does not enforce a limit on the number of fragments. A malicious WebSocket server can stream many small or empty continuation frames that each pass per-frame and cumulative-size validation, collectively causing unbounded memory growth in the client process. The result is memory exhaustion and a denial of service. Affected applications are those using the undici WebSocket client (new WebSocket(...)) or the WebSocketStream API that can be induced to connect to an attacker-controlled or compromised WebSocket endpoint. All releases starting at undici 6.17.0 are affected. Patches: Upgrade to undici >= 6.26.0, >= 7.28.0, or >= 8.5.0. Workarounds: No workaround is available. The fix must be applied through an upgrade.
CVE-2025-61726 2 Go Standard Library, Golang 2 Net/url, Go 2026-09-11 7.5 High
The net/url package does not set a limit on the number of query parameters in a query. While the maximum size of query parameters in URLs is generally limited by the maximum request header size, the net/http.Request.ParseForm method can parse large URL-encoded forms. Parsing a large form containing many unique query parameters can cause excessive memory consumption.
CVE-2026-45763 1 Oisf 1 Suricata 2026-09-11 5.9 Medium
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Starting in version 8.0.0 and prior to version 8.0.5, when Lua rule execution is enabled, the Lua sandbox memory limit was not consistently enforced for new allocations. Certain Lua allocation patterns could exceed `security.lua.max-bytes` without triggering the intended memory limit, making the configured sandbox limit unreliable. This requires Lua rules to be enabled and an affected Lua script/rule to be loaded. Version 8.0.5 contains a fix. As a workaround, disable `security.lua.allow-rules` unless Lua rules are required.
CVE-2026-88045 1 Rclone 1 Rclone 2026-09-11 7.5 High
rclone is a command-line program to sync files and directories to and from different cloud storage providers. From 1.75.0 until 1.75.1, the serve S3 streamed multipart path in cmd/serve/s3/multipart.go passes attacker-controlled contentLength to multipart.NewRW().Reserve before reading request-body bytes. waitForTurn admits the current part and one oversized part when the buffer is empty despite --multipart-streaming-buffer-limit, and lib/pool allocates 1 MiB pages according to Content-Length or X-Amz-Decoded-Content-Length. A network client can retain or multiply these reservations without sending the declared body, exhausting process or host memory or permanently blocking request handlers. Anonymous S3 deployments require no credentials, while deployments using auth_key require an accepted S3 key. This issue is fixed in version 1.75.1.
CVE-2026-72978 1 Microsoft 14 Windows 10 1607, Windows 10 1809, Windows Server 2012 and 11 more 2026-09-10 5.9 Medium
Allocation of resources without limits or throttling in Active Directory Federation Services (AD FS) allows an unauthorized attacker to deny service over a network.
CVE-2026-73541 2 Zenhive, Zenhive 3 Mpp, Machine Payments Protocol, Mpp 2026-09-10 8.2 High
Allocation of Resources Without Limits or Throttling in ZenHive mpp allows an unauthenticated remote client to drain the fee-payer wallet through concurrent sponsored payments, denying service to legitimate payers once it is empty. MPP.Methods.Tempo.FeePayerPolicy enforces its ceilings (max_gas, max_fee_per_gas, max_priority_fee_per_gas, the worst-case gas_limit * max_fee_per_gas <= max_total_fee budget cap, and a validity window) against one transaction at a time, and nothing accounts for exposure across concurrent requests. reserve_hash_atomic/2 is keyed on the transaction hash, so it prevents duplicate broadcast of the same signed transaction but not N distinct sponsored transactions carrying distinct expiring nonces. Committed sponsor exposure is therefore N times max_total_fee, bounded by nothing in the library, and the default 900 second validity window lets co-signed transactions stay broadcastable and uncounted for that entire period. This issue affects mpp: from 0.2.0 before 0.12.0.
CVE-2026-15588 1 Redhat 15 Cert Manager, Discovery, Enterprise Linux and 12 more 2026-09-10 5.3 Medium
A denial-of-service and resource exhaustion vulnerability exists within the `GDBus` component of GLib. The `gdbusauth` authentication mechanism fails to enforce proper length limitations on data lines read from a client. An unauthenticated local or remote attacker can exploit this lack of input validation by sending excessively long streams of data, causing the application to consume massive amounts of system memory and CPU, potentially leading to a crash or system hang.
CVE-2026-4897 2 Freedesktop, Redhat 5 Polkit, Enterprise Linux, Hummingbird and 2 more 2026-09-10 5.5 Medium
A flaw was found in polkit. A local user can exploit this by providing a specially crafted, excessively long input to the `polkit-agent-helper-1` setuid binary via standard input (stdin). This unbounded input can lead to an out-of-memory (OOM) condition, resulting in a Denial of Service (DoS) for the system.
CVE-2026-85664 1 Chroma-core 1 Chroma 2026-09-10 7.5 High
Chroma 1.5.9 fails to validate maximum bounds on HNSW index parameters max_neighbors, ef_construction, and ef_search in collection-create requests. Unauthenticated attackers can supply arbitrarily large parameter values to exhaust server memory and cause denial of service during index compaction.
CVE-2026-85581 2 B3log, Siyuan 2 Siyuan, Siyuan 2026-09-10 7.5 High
SiYuan before v3.8.2 contains a denial of service vulnerability in the unauthenticated /api/system/uiproc endpoint that accepts and retains attacker-controlled process identifiers without size limits or authentication. Attackers can send repeated requests with unique identifiers to exhaust process memory and degrade service availability.
CVE-2026-18649 1 Redhat 4 Enterprise Linux, Enterprise Linux Eus, Rhel E4s and 1 more 2026-09-10 7.5 High
A flaw was found in the GStreamer gst-plugins-good package. The rtph264depay and rtph265depay RTP depayloader elements do not enforce a maximum size limit on the reassembly buffer used during fragmented RTP packet processing. A remote, unauthenticated attacker can send a continuous stream of RTP fragments without ever transmitting an end-of-fragment marker, causing the reassembly buffer to grow without bound until process memory is exhausted. This results in a denial of service through process termination.
CVE-2026-47885 2 Spring, Vmware 2 Spring Framework, Spring Framework 2026-09-10 7.5 High
The PartEventHttpMessageReader in Spring WebFlux does not enforce the maxPartSize limit when maxInMemorySize is set to -1. Spring Framework 7.0.0 - 7.0.8 Spring Framework 6.2.0 - 6.2.19 Spring Framework 6.1.0 - 6.1.28
CVE-2023-54394 1 Pmmp 1 Pocketmine-mp 2026-09-10 4.3 Medium
PocketMine-MP before 4.18.0-ALPHA2 fails to rate-limit mismatch type InventoryTransactionPacket requests, allowing attackers to trigger excessive inventory synchronization. Attackers can send numerous mismatch transactions to force the server to transmit large amounts of serialized inventory data, consuming significant bandwidth without authentication.
CVE-2026-3039 2 Isc, Redhat 2 Bind, Hummingbird 2026-09-10 7.5 High
BIND servers that are configured to use TKEY-based authentication via GSS-API tokens are vulnerable to excessive memory consumption when receiving and processing maliciously-constructed packets. Typically these servers will be found in Active Directory integrated DNS deployments and/or Kerberos-secured DNS environments. This issue affects BIND 9 versions 9.0.0 through 9.16.50, 9.18.0 through 9.18.48, 9.20.0 through 9.20.22, 9.21.0 through 9.21.21, 9.9.3-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.48-S1, and 9.20.9-S1 through 9.20.22-S1.
CVE-2026-1519 1 Isc 1 Bind 2026-09-10 7.5 High
If a BIND resolver is performing DNSSEC validation and encounters a maliciously crafted zone, the resolver may consume excessive CPU. Authoritative-only servers are generally unaffected, although there are circumstances where authoritative servers may make recursive queries (see: https://kb.isc.org/docs/why-does-my-authoritative-server-make-recursive-queries). This issue affects BIND 9 versions 9.11.0 through 9.16.50, 9.18.0 through 9.18.46, 9.20.0 through 9.20.20, 9.21.0 through 9.21.19, 9.11.3-S1 through 9.16.50-S1, 9.18.11-S1 through 9.18.46-S1, and 9.20.9-S1 through 9.20.20-S1.
CVE-2026-87011 1 Open-webui 1 Open-webui 2026-09-10 7.5 High
Open WebUI is an extensible, feature-rich, and user-friendly self-hosted AI platform. From 0.9.0 until 0.11.1, the unauthenticated POST /oauth/backchannel-logout handler in backend/open_webui/utils/oauth.py fetched the OIDC discovery document and signing keys before validating a submitted logout token. Each request repeated uncached network fetches, and the signing-key lookup blocked the async event loop, so requests carrying invalid tokens could stall the single-worker instance and amplify traffic to the identity provider when ENABLE_OAUTH_BACKCHANNEL_LOGOUT was enabled. This issue is fixed in version 0.11.1.
CVE-2026-78662 1 Golang 1 Crypto 2026-09-10 7.5 High
Previously, a channel registered in the mux's chanList is not usable until it is established. A malicious peer was able flood the channel's incomingRequests, deadlocking the entire connection. Now, we add an atomic established state, set when a channel becomes usable. Until such a time, handlePacket drops every packet other than the open confirmation/failure, without blocking and without tearing down the connection.
CVE-2026-62649 1 Siemens 1 Reyrolle 7sr5 2026-09-09 7.5 High
A vulnerability has been identified in Reyrolle 7SR5 (All versions < V2.70). The web server does not properly limit or manage system resources when processing a high volume of concurrent HTTP requests. This could allow an unauthenticated remote attacker to cause the entire device to crash and reboot, resulting in a denial-of-service condition.
CVE-2026-86452 2 Misp, Misp-project 2 Misp, Misp 2026-09-09 7.5 High
Affected versions of MISP permit unauthenticated or weakly constrained request paths to perform persistent work without adequate input bounds or rate limiting. The users/forgot password-reset endpoint accepted an attacker-controlled email value without first imposing a reasonable length bound or validating its format. That value was then used to create an audit log entry and queue a password-reset job, causing the supplied value to be persisted more than once per request. The commit explicitly states that an unbounded unauthenticated request field was stored twice per call with no throttle. The fix adds: * a maximum email input length of 1024 bytes; * email-format validation before persistent work; * a per-source pre-authentication request budget; * HTTP 429 responses when that budget is exceeded; * a 15-minute cooldown for API-access request emails; * POST-only handling and CSRF protection for the API-access request endpoint. The new flood filter is specifically intended to limit persistent storage costs from anonymous requests such as password resets, registrations, and failed REST authentication attempts. Version affected: ≤2.5.45
CVE-2026-40192 2 Python, Python-pillow 2 Pillow, Pillow 2026-09-09 7.5 High
Pillow is a Python imaging library. Versions 10.3.0 through 12.1.1 did not limit the amount of GZIP-compressed data read when decoding a FITS image, making them vulnerable to decompression bomb attacks. A specially crafted FITS file could cause unbounded memory consumption, leading to denial of service (OOM crash or severe performance degradation). If users are unable to immediately upgrade, they should only open specific image formats, excluding FITS, as a workaround.
