CVE-2025-59045 2026-04-15 N/A
Stalwart is a mail and collaboration server. Starting in version 0.12.0 and prior to version 0.13.3, a memory exhaustion vulnerability exists in Stalwart's CalDAV implementation that allows authenticated attackers to cause denial-of-service by triggering unbounded memory consumption through recurring event expansion. An authenticated attacker can crash the Stalwart server by creating recurring events with large payloads and triggering their expansion through CalDAV REPORT requests. A single malicious request expanding 300 events with 1000-character descriptions can consume up to 2 GB of memory. The vulnerability exists in the `ArchivedCalendarEventData.expand` function, which processes CalDAV `REPORT` requests with event expansion. When a client requests recurring events in their expanded form using the `<C:expand>` element, the server stores all expanded event instances in memory without enforcing size limits. Users should upgrade to Stalwart version 0.13.3 or later to receive a fix. If immediate upgrading is not possible, implement memory limits at the container/system level; monitor server memory usage for unusual spikes; consider rate limiting CalDAV REPORT requests; and restrict CalDAV access to trusted users only.
CVE-2025-54575 1 Sixlabors 1 Imagesharp 2026-04-15 5.3 Medium
ImageSharp is a 2D graphics library. In versions below 2.1.11 and 3.0.0 through 3.1.10, a specially crafted GIF file containing a malformed comment extension block (with a missing block terminator) can cause the ImageSharp GIF decoder to enter an infinite loop while attempting to skip the block. This leads to a denial of service. Applications processing untrusted GIF input should upgrade to a patched version. This issue is fixed in versions 2.1.11 and 3.1.11.
CVE-2025-54572 1 Saml-toolkits 1 Ruby-saml 2026-04-15 N/A
The Ruby SAML library is for implementing the client side of a SAML authorization. In versions 1.18.0 and below, a denial-of-service vulnerability exists in ruby-saml even with the message_max_bytesize setting configured. The vulnerability occurs because the SAML response is validated for Base64 format prior to checking the message size, leading to potential resource exhaustion. This is fixed in version 1.18.1.
CVE-2025-48738 1 Strangebee 1 Thehive 2026-04-15 N/A
An e-mail flooding vulnerability in StrangeBee TheHive 5.2.0 before 5.2.16, 5.3.0 before 5.3.11, 5.4.0 before 5.4.10, and 5.5.0 before 5.5.1 allows unauthenticated remote attackers to use the password reset feature without limits. This can lead to several consequences, including mailbox storage exhaustion for targeted users, reputation damage to the SMTP server, potentially causing it to be blacklisted, and overload of the SMTP server's outbound mail queue.
CVE-2025-47908 1 Golang 1 Cors 2026-04-15 7.5 High
Middleware causes a prohibitive amount of heap allocations when processing malicious preflight requests that include a Access-Control-Request-Headers (ACRH) header whose value contains many commas. This behavior can be abused by attackers to produce undue load on the middleware/server as an attempt to cause a denial of service.
CVE-2025-46807 2026-04-15 5.3 Medium
A Allocation of Resources Without Limits or Throttling vulnerability in sslh allows attackers to easily exhaust the file descriptors in sslh and deny legitimate users service.This issue affects sslh before 2.2.4.
CVE-2025-45526 2026-04-15 2.9 Low
A denial of service (DoS) vulnerability has been identified in the JavaScript library microlight version 0.0.7. This library, used for syntax highlighting, does not limit the size of textual content it processes in HTML elements with the microlight class. When excessively large content (e.g., 100 million characters) is processed, the reset function in microlight.js consumes excessive memory and CPU resources, causing browser crashes or unresponsiveness. An attacker can exploit this vulnerability by tricking a user into visiting a malicious web page containing a microlight element with large content, resulting in a denial of service. NOTE: this is disputed by multiple parties because a large amount of memory and CPU resources is expected to be needed for content of that size.
CVE-2025-40570 1 Siemens 1 Siprotec 5 2026-04-15 2.4 Low

A vulnerability affecting HPE Networking Instant On Access Points has been identified where a device processing a specially crafted packet could enter a non-responsive state, in some cases requiring a hard reset to re-establish services. A malicious actor could leverage this vulnerability to conduct a Denial-of-Service attack on a target network.
CVE-2025-32959 2026-04-15 6.5 Medium
CUBA Platform is a high level framework for enterprise applications development. Prior to version 7.2.23, the local file storage implementation does not restrict the size of uploaded files. An attacker could exploit this by uploading excessively large files, potentially causing the server to run out of space and return HTTP 500 error, resulting in a denial of service. This issue has been patched in version 7.2.23. A workaround is provided on the Jmix documentation website.
CVE-2024-12705 1 Redhat 2 Enterprise Linux, Openshift 2026-04-15 7.5 High
Clients using DNS-over-HTTPS (DoH) can exhaust a DNS resolver's CPU and/or memory by flooding it with crafted valid or invalid HTTP/2 traffic. This issue affects BIND 9 versions 9.18.0 through 9.18.32, 9.20.0 through 9.20.4, 9.21.0 through 9.21.3, and 9.18.11-S1 through 9.18.32-S1.
CVE-2025-25186 1 Redhat 2 Enterprise Linux, Logging 2026-04-15 6.5 Medium
Net::IMAP implements Internet Message Access Protocol (IMAP) client functionality in Ruby. Starting in version 0.3.2 and prior to versions 0.3.8, 0.4.19, and 0.5.6, there is a possibility for denial of service by memory exhaustion in `net-imap`'s response parser. At any time while the client is connected, a malicious server can send can send highly compressed `uid-set` data which is automatically read by the client's receiver thread. The response parser uses `Range#to_a` to convert the `uid-set` data into arrays of integers, with no limitation on the expanded size of the ranges. Versions 0.3.8, 0.4.19, 0.5.6, and higher fix this issue. Additional details for proper configuration of fixed versions and backward compatibility are available in the GitHub Security Advisory.
CVE-2025-32380 2026-04-15 7.5 High
The Apollo Router Core is a configurable, high-performance graph router written in Rust to run a federated supergraph that uses Apollo Federation 2. A vulnerability in Apollo Router's usage of Apollo Compiler allowed queries with deeply nested and reused named fragments to be prohibitively expensive to validate. This could lead to excessive resource consumption and denial of service. Apollo Router's usage of Apollo Compiler has been updated so that validation logic processes each named fragment only once, preventing redundant traversal. This has been remediated in apollo-router versions 1.61.2 and 2.1.1.
CVE-2025-30409 2026-04-15 N/A
Denial of service due to allocation of resources without limits. The following products are affected: Acronis Cyber Protect Cloud Agent (Windows) before build 39904, Acronis Cyber Protect 17 (Windows) before build 41186.
CVE-2025-2813 1 Phoenixcontact 2 Axl F Bk Eip, Axl F Bk Pn 2026-04-15 7.5 High
An unauthenticated remote attacker can cause a Denial of Service by sending a large number of requests to the http service on port 80.
CVE-2023-45290 1 Redhat 20 Advanced Cluster Security, Ansible Automation Platform, Ceph Storage and 17 more 2026-04-15 6.5 Medium
When parsing a multipart form (either explicitly with Request.ParseMultipartForm or implicitly with Request.FormValue, Request.PostFormValue, or Request.FormFile), limits on the total size of the parsed form were not applied to the memory consumed while reading a single form line. This permits a maliciously crafted input containing very long lines to cause allocation of arbitrarily large amounts of memory, potentially leading to memory exhaustion. With fix, the ParseMultipartForm function now correctly limits the maximum size of form lines.
CVE-2025-24341 2026-04-15 6.5 Medium
A vulnerability in the web application of ctrlX OS allows a remote authenticated (low-privileged) attacker to induce a Denial-of-Service (DoS) condition on the device via multiple crafted HTTP requests. In the worst case, a full power cycle is needed to regain control of the device.
