CVE-2025-68480 1 Marshmallow Project 1 Marshmallow 2026-04-15 5.3 Medium
Marshmallow is a lightweight library for converting complex objects to and from simple Python datatypes. In versions from 3.0.0rc1 to before 3.26.2 and from 4.0.0 to before 4.1.2, Schema.load(data, many=True) is vulnerable to denial of service attacks. A moderately sized request can consume a disproportionate amount of CPU time. This issue has been patched in version 3.26.2 and 4.1.2.
CVE-2024-34703 1 Randombit 1 Botan 2026-04-15 7.5 High
Botan is a C++ cryptography library. X.509 certificates can identify elliptic curves using either an object identifier or using explicit encoding of the parameters. Prior to versions 3.3.0 and 2.19.4, an attacker could present an ECDSA X.509 certificate using explicit encoding where the parameters are very large. The proof of concept used a 16Kbit prime for this purpose. When parsing, the parameter is checked to be prime, causing excessive computation. This was patched in 2.19.4 and 3.3.0 to allow the prime parameter of the elliptic curve to be at most 521 bits. No known workarounds are available. Note that support for explicit encoding of elliptic curve parameters is deprecated in Botan.
CVE-2025-30204 1 Redhat 19 Acm, Advanced Cluster Security, Cryostat and 16 more 2026-04-15 7.5 High
golang-jwt is a Go implementation of JSON Web Tokens. Starting in version 3.2.0 and prior to versions 5.2.2 and 4.5.2, the function parse.ParseUnverified splits (via a call to strings.Split) its argument (which is untrusted data) on periods. As a result, in the face of a malicious request whose Authorization header consists of Bearer followed by many period characters, a call to that function incurs allocations to the tune of O(n) bytes (where n stands for the length of the function's argument), with a constant factor of about 16. This issue is fixed in 5.2.2 and 4.5.2.
CVE-2025-42873 2 Sap, Sap Se 2 Sapui5, Sapui5 2026-04-15 5.9 Medium
SAPUI5 (and OpenUI5) packages use outdated 3rd party libraries with known security vulnerabilities. When markdown-it encounters special malformed input, it fails to terminate properly, resulting in an infinite loop. This Denial of Service via infinite loop causes high CPU usage and system unresponsiveness due to a blocked processing thread. This vulnerability has no impact on confidentiality or integrity but has a high impact on system availability.
CVE-2026-35665 1 Openclaw 1 Openclaw 2026-04-13 5.3 Medium
OpenClaw before 2026.3.24 contains an incomplete fix for CVE-2026-32011 where the Feishu webhook handler accepts request bodies with permissive limits of 1MB and 30-second timeout before signature verification. An unauthenticated attacker can exhaust server connection resources by sending concurrent slow HTTP POST requests to the Feishu webhook endpoint, blocking legitimate webhook deliveries.
CVE-2025-46598 1 Bitcoin 1 Bitcoin Core 2026-04-02 5.3 Medium
Bitcoin Core through 29.0 allows a denial of service via a crafted transaction.
CVE-2025-66564 2 Linuxfoundation, Sigstore 2 Sigstore Timestamp Authority, Timestamp Authority 2026-03-17 7.5 High
Sigstore Timestamp Authority is a service for issuing RFC 3161 timestamps. Prior to 2.0.3, Function api.ParseJSONRequest currently splits (via a call to strings.Split) an optionally-provided OID (which is untrusted data) on periods. Similarly, function api.getContentType splits the Content-Type header (which is also untrusted data) on an application string. As a result, in the face of a malicious request with either an excessively long OID in the payload containing many period characters or a malformed Content-Type header, a call to api.ParseJSONRequest or api.getContentType incurs allocations of O(n) bytes (where n stands for the length of the function's argument). This vulnerability is fixed in 2.0.3.
CVE-2025-66506 2 Linuxfoundation, Sigstore 2 Fulcio, Fulcio 2026-03-10 7.5 High
Fulcio is a free-to-use certificate authority for issuing code signing certificates for an OpenID Connect (OIDC) identity. Prior to 1.8.3, function identity.extractIssuerURL splits (via a call to strings.Split) its argument (which is untrusted data) on periods. As a result, in the face of a malicious request with an (invalid) OIDC identity token in the payload containing many period characters, a call to extractIssuerURL incurs allocations to the tune of O(n) bytes (where n stands for the length of the function's argument), with a constant factor of about 16. This vulnerability is fixed in 1.8.3.
CVE-2025-49643 1 Zabbix 2 Frontend, Zabbix 2026-02-06 6.5 Medium
An authenticated Zabbix user (including Guest) is able to cause disproportionate CPU load on the webserver by sending specially crafted parameters to /imgstore.php, leading to potential denial of service.

CVE-2025-31987 1 Hcltech 1 Connections Docs 2025-11-21 4.8 Medium
HCL Connections Docs may mishandle validation of certain uploaded documents leading to denial of service due to resource exhaustion.
CVE-2025-43857 1 Ruby-lang 1 Net\ 2025-11-21 6.5 Medium
Net::IMAP implements Internet Message Access Protocol (IMAP) client functionality in Ruby. Prior to versions 0.5.7, 0.4.20, 0.3.9, and 0.2.5, there is a possibility for denial of service by memory exhaustion when net-imap reads server responses. At any time while the client is connected, a malicious server can send can send a "literal" byte count, which is automatically read by the client's receiver thread. The response reader immediately allocates memory for the number of bytes indicated by the server response. This should not be an issue when securely connecting to trusted IMAP servers that are well-behaved. It can affect insecure connections and buggy, untrusted, or compromised servers (for example, connecting to a user supplied hostname). This issue has been patched in versions 0.5.7, 0.4.20, 0.3.9, and 0.2.5.
CVE-2025-26516 1 Netapp 1 Storagegrid 2025-09-23 5.3 Medium
StorageGRID (formerly StorageGRID Webscale) versions prior to 11.8.0.15 and 11.9.0.8 are susceptible to a Denial of Service vulnerability. Successful exploit could allow an unauthenticated attacker to cause a Denial of Service on the Admin node.
CVE-2025-24356 1 Fastd Project 1 Fastd 2025-08-27 7.5 High
fastd is a VPN daemon which tunnels IP packets and Ethernet frames over UDP. When receiving a data packet from an unknown IP address/port combination, fastd will assume that one of its connected peers has moved to a new address and initiate a reconnect by sending a handshake packet. This "fast reconnect" avoids having to wait for a session timeout (up to ~90s) until a new connection is established. Even a 1-byte UDP packet just containing the fastd packet type header can trigger a much larger handshake packet (~150 bytes of UDP payload). Including IPv4 and UDP headers, the resulting amplification factor is roughly 12-13. By sending data packets with a spoofed source address to fastd instances reachable on the internet, this amplification of UDP traffic might be used to facilitate a Distributed Denial of Service attack. This vulnerability is fixed in v23.
CVE-2025-53633 1 Ctfer-io 1 Chall-manager 2025-08-14 9.8 Critical
Chall-Manager is a platform-agnostic system able to start Challenges on Demand of a player. When decoding a scenario (i.e. a zip archive), the size of the decoded content is not checked, potentially leading to zip bombs decompression. Exploitation does not require authentication nor authorization, so anyone can exploit it. It should nonetheless not be exploitable as it is highly recommended to bury Chall-Manager deep within the infrastructure due to its large capabilities, so no users could reach the system. Patch has been implemented by commit 14042aa and shipped in v0.1.4.
CVE-2024-28214 1 Naver 1 Ngrinder 2025-05-07 2.7 Low
nGrinder before 3.5.9 allows to set delay without limitation, which could be the cause of Denial of Service by remote attacker.
CVE-2021-38447 1 Objectcomputing 1 Opendds 2025-04-16 8.6 High
OCI OpenDDS versions prior to 3.18.1 are vulnerable when an attacker sends a specially crafted packet to flood target devices with unwanted traffic, which may result in a denial-of-service condition.
CVE-2024-55628 1 Oisf 1 Suricata 2025-03-31 7.5 High
Suricata is a network Intrusion Detection System, Intrusion Prevention System and Network Security Monitoring engine. Prior to version 7.0.8, DNS resource name compression can lead to small DNS messages containing very large hostnames which can be costly to decode, and lead to very large DNS log records. While there are limits in place, they were too generous. The issue has been addressed in Suricata 7.0.8.
