CVE-2026-27695 1 Zeroae 1 Zae-limiter 2026-04-18 4.3 Medium
zae-limiter is a rate limiting library using the token bucket algorithm. Prior to version 0.10.1, all rate limit buckets for a single entity share the same DynamoDB partition key (`namespace/ENTITY#{id}`). A high-traffic entity can exceed DynamoDB's per-partition throughput limits (~1,000 WCU/sec), causing throttling that degrades service for that entity — and potentially co-located entities in the same partition. Version 0.10.1 fixes the issue.
CVE-2026-21965 1 Oracle 1 Mysql Server 2026-04-18 2.7 Low
Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Pluggable Auth). Supported versions that are affected are 9.0.0-9.5.0. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of MySQL Server. CVSS 3.1 Base Score 2.7 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L).
CVE-2026-22025 1 Nasa 1 Cryptolib 2026-04-18 3.7 Low
CryptoLib provides a software-only solution using the CCSDS Space Data Link Security Protocol - Extended Procedures (SDLS-EP) to secure communications between a spacecraft running the core Flight System (cFS) and a ground station. Prior to version 1.4.3, when the KMC server returns a non-200 HTTP status code, cryptography_encrypt() and cryptography_decrypt() return immediately without freeing previously allocated buffers. Each failed request leaks approximately 467 bytes. Repeated failures (from a malicious server or network issues) can gradually exhaust memory. This issue has been patched in version 1.4.3.
CVE-2026-23490 2 Debian, Pyasn1 2 Debian Linux, Pyasn1 2026-04-18 7.5 High
pyasn1 is a generic ASN.1 library for Python. Prior to 0.6.2, a Denial-of-Service issue has been found that leads to memory exhaustion from malformed RELATIVE-OID with excessive continuation octets. This vulnerability is fixed in 0.6.2.
CVE-2026-21434 1 Quic-go 1 Webtransport-go 2026-04-18 5.3 Medium
webtransport-go is an implementation of the WebTransport protocol. From 0.3.0 to 0.9.0, an attacker can cause excessive memory consumption in webtransport-go's session implementation by sending a WT_CLOSE_SESSION capsule containing an excessively large Application Error Message. The implementation does not enforce the draft-mandated limit of 1024 bytes on this field, allowing a peer to send an arbitrarily large message payload that is fully read and stored in memory. This allows an attacker to consume an arbitrary amount of memory. The attacker must transmit the full payload to achieve the memory consumption, but the lack of any upper bound makes large-scale attacks feasible given sufficient bandwidth. This vulnerability is fixed in 0.10.0.
CVE-2026-27887 1 Spinframework 3 Containerd-shim-spin, Spin, Spinkube 2026-04-18 N/A
Spin is an open source developer tool for building and running serverless applications powered by WebAssembly. When Spin is configured to allow connections to a database or web server which could return responses of unbounded size (e.g. tables with many rows or large content bodies), Spin may in some cases attempt to buffer the entire response before delivering it to the guest, which can lead to the host process running out of memory, panicking, and crashing. In addition, a malicious guest application could incrementally insert a large number of rows or values into a database and then retrieve them all in a single query, leading to large host allocations. Spin 3.6.1, SpinKube 0.6.2, and `containerd-shim-spin` 0.22.1 have been patched to address the issue. As a workaround, configure Spin to only allow access to trusted databases and HTTP servers which limit response sizes.
CVE-2026-22917 2 Sick, Sick Ag 3 Tdc-x401gl, Tdc-x401gl Firmware, Tdc-x401gl 2026-04-18 4.3 Medium
Improper input handling in a system endpoint may allow attackers to overload resources, causing a denial of service.
CVE-2026-21964 1 Oracle 2 Mysql, Mysql Server 2026-04-18 4.9 Medium
Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Thread Pooling). Supported versions that are affected are 8.0.0-8.0.44, 8.4.0-8.4.7 and 9.0.0-9.5.0. Easily exploitable vulnerability allows high privileged attacker with network access via multiple protocols to compromise MySQL Server. Successful attacks of this vulnerability can result in unauthorized ability to cause a hang or frequently repeatable crash (complete DOS) of MySQL Server. CVSS 3.1 Base Score 4.9 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:H).
CVE-2026-23962 1 Joinmastodon 1 Mastodon 2026-04-18 7.5 High
Mastodon is a free, open-source social network server based on ActivityPub. Mastodon versions before v4.3.18, v4.4.12, and v4.5.5 do not have a limit on the maximum number of poll options for remote posts, allowing attackers to create polls with a very large amount of options, greatly increasing resource consumption. Depending on the number of poll options, an attacker can cause disproportionate resource usage in both Mastodon servers and clients, potentially causing Denial of Service either server-side or client-side. Mastodon versions v4.5.5, v4.4.12, v4.3.18 are patched.
CVE-2026-22258 1 Oisf 1 Suricata 2026-04-18 7.5 High
Suricata is a network IDS, IPS and NSM engine. Prior to versions 8.0.3 and 7.0.14, crafted DCERPC traffic can cause Suricata to expand a buffer w/o limits, leading to memory exhaustion and the process getting killed. While reported for DCERPC over UDP, it is believed that DCERPC over TCP and SMB are also vulnerable. DCERPC/TCP in the default configuration should not be vulnerable as the default stream depth is limited to 1MiB. Versions 8.0.3 and 7.0.14 contain a patch. Some workarounds are available. For DCERPC/UDP, disable the parser. For DCERPC/TCP, the `stream.reassembly.depth` setting will limit the amount of data that can be buffered. For DCERPC/SMB, the `stream.reassembly.depth` can be used as well, but is set to unlimited by default. Imposing a limit here may lead to loss of visibility in SMB.
CVE-2026-22780 1 Rizin 1 Rizin 2026-04-18 4.4 Medium
Rizin is a UNIX-like reverse engineering framework and command-line toolset. Prior to 0.8.2, a heap overflow can be exploited when a malicious mach0 file, having bogus entries for the dyld chained segments, is parsed by rizin. This vulnerability is fixed in 0.8.2.
CVE-2026-23689 1 Sap 2 Advanced Planning And Optimization, Supply Chain Management 2026-04-18 7.7 High
Due to an uncontrolled resource consumption (Denial of Service) vulnerability, an authenticated attacker with regular user privileges and network access can repeatedly invoke a remote-enabled function module with an excessively large loop-control parameter. This triggers prolonged loop execution that consumes excessive system resources, potentially rendering the system unavailable. Successful exploitation results in a denial-of-service condition that impacts availability, while confidentiality and integrity remain unaffected.
CVE-2026-1847 1 Mongodb 1 Mongodb 2026-04-18 6.5 Medium
Inserting certain large documents into a replica set could lead to replica set secondaries not being able to fetch the oplog from the primary. This could stall replication inside the replica set leading to server crash.
CVE-2026-1456 1 Gitlab 1 Gitlab 2026-04-18 6.5 Medium
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.7 before 18.7.4, and 18.8 before 18.8.4 that could have allowed an unauthenticated user to cause denial of service through CPU exhaustion by submitting specially crafted markdown files that trigger exponential processing in markdown preview.
CVE-2026-27571 2 Linuxfoundation, Nats 2 Nats-server, Nats Server 2026-04-18 5.9 Medium
NATS-Server is a High-Performance server for NATS.io, a cloud and edge native messaging system. The WebSockets handling of NATS messages handles compressed messages via the WebSockets negotiated compression. Prior to versions 2.11.2 and 2.12.3, the implementation bound the memory size of a NATS message but did not independently bound the memory consumption of the memory stream when constructing a NATS message which might then fail validation for size reasons. An attacker can use a compression bomb to cause excessive memory consumption, often resulting in the operating system terminating the server process. The use of compression is negotiated before authentication, so this does not require valid NATS credentials to exploit. The fix, present in versions 2.11.2 and 2.12.3, was to bounds the decompression to fail once the message was too large, instead of continuing on. The vulnerability only affects deployments which use WebSockets and which expose the network port to untrusted end-points.
CVE-2026-27572 1 Bytecodealliance 1 Wasmtime 2026-04-18 7.5 High
Wasmtime is a runtime for WebAssembly. Prior to versions 24.0.6, 36.0.6, 4.0.04, 41.0.4, and 42.0.0, Wasmtime's implementation of the `wasi:http/types.fields` resource is susceptible to panics when too many fields are added to the set of headers. Wasmtime's implementation in the `wasmtime-wasi-http` crate is backed by a data structure which panics when it reaches excessive capacity and this condition was not handled gracefully in Wasmtime. Panicking in a WASI implementation is a Denial of Service vector for embedders and is treated as a security vulnerability in Wasmtime. Wasmtime 24.0.6, 36.0.6, 40.0.4, 41.0.4, and 42.0.0 patch this vulnerability and return a trap to the guest instead of panicking. There are no known workarounds at this time. Embedders are encouraged to update to a patched version of Wasmtime.
CVE-2026-1725 1 Gitlab 1 Gitlab 2026-04-18 5.3 Medium
GitLab has remediated an issue in GitLab CE/EE affecting versions from 18.9 before 18.9.1 that could have under certain conditions, allowed an unauthenticated user to cause denial of service by sending specially crafted requests to a CI jobs API endpoint.
CVE-2026-29609 1 Openclaw 1 Openclaw 2026-04-18 7.5 High
OpenClaw versions prior to 2026.2.14 contain a denial of service vulnerability in the fetchWithGuard function that allocates entire response payloads in memory before enforcing maxBytes limits. Remote attackers can trigger memory exhaustion by serving oversized responses without content-length headers to cause availability loss.
CVE-2026-23405 1 Linux 1 Linux Kernel 2026-04-18 N/A
In the Linux kernel, the following vulnerability has been resolved: apparmor: fix: limit the number of levels of policy namespaces Currently the number of policy namespaces is not bounded relying on the user namespace limit. However policy namespaces aren't strictly tied to user namespaces and it is possible to create them and nest them arbitrarily deep which can be used to exhaust system resource. Hard cap policy namespaces to the same depth as user namespaces.
CVE-2026-23404 1 Linux 1 Linux Kernel 2026-04-18 N/A
In the Linux kernel, the following vulnerability has been resolved: apparmor: replace recursive profile removal with iterative approach The profile removal code uses recursion when removing nested profiles, which can lead to kernel stack exhaustion and system crashes. Reproducer: $ pf='a'; for ((i=0; i<1024; i++)); do echo -e "profile $pf { \n }" | apparmor_parser -K -a; pf="$pf//x"; done $ echo -n a > /sys/kernel/security/apparmor/.remove Replace the recursive __aa_profile_list_release() approach with an iterative approach in __remove_profile(). The function repeatedly finds and removes leaf profiles until the entire subtree is removed, maintaining the same removal semantic without recursion.
