CVE-2026-9602 1 Mattermost 2 Mattermost, Mattermost Desktop 2026-07-17 5.7 Medium
Mattermost Desktop App versions <=6.2 6.0.2 5.6.13.0 fail to validate payloads sent from the Mattermost Web App to the Desktop App which allows a malicious server owner to crash the Mattermost Desktop App via changing the payload of a method to a malformed one. Mattermost Advisory ID: MMSA-2026-00678
CVE-2026-33754 1 Wazuh 1 Wazuh 2026-07-17 6.5 Medium
Wazuh is a free and open source platform used for threat prevention, detection, and response. In versions 3.9.0 and above, prior to 4.14.5, a remote attacker can trigger memory exhaustion in the cluster protocol parser by sending a crafted message header with an arbitrarily large payload length. The length is trusted before authentication/decryption and used directly to allocate memory, allowing unauthenticated denial of service of the cluster service. This issue has been fixed in version 4.14.5.
CVE-2026-33382 1 Grafana 1 Grafana 2026-07-16 7.5 High
Several Grafana API endpoints, some of them unauthenticated, do not limit the size of the request body before processing it. An attacker can send very large payloads that force excessive memory allocation, potentially exhausting memory and causing a denial of service.
CVE-2026-8609 1 Grafana 1 Grafana 2026-07-16 5.3 Medium
An unauthenticated attacker can repeatedly call Grafana's OAuth login route with unique values, causing unbounded memory growth that can eventually exhaust memory and crash the Grafana instance (denial of service).
CVE-2026-55440 1 Microsoft 1 Ufo 2026-07-16 6.5 Medium
Microsoft UFO open-source framework for intelligent automation across devices and platforms. Prior to 3.0.7, the COMMAND_RESULTS handler in ufo/server/ws/handler.py called get_or_create_session in ufo/server/services/session_manager.py without owner_client_id, allowing an authenticated client to create an unowned attacker-chosen session_id such as constellation_task_id = f"{task_name}@{task_id}" and deny the legitimate owner or exhaust memory with phantom sessions. This issue is fixed in version 3.0.7.
CVE-2026-46627 2 Symfony, Twigphp 2 Twig, Twig 2026-07-16 6.5 Medium
Twig is a template language for PHP. Prior to 3.26.0, the Twig sandbox does not prevent a template from consuming CPU, memory, or wall-clock time, even under the strictest allow-list, allowing untrusted templates to cause resource exhaustion. This issue is addressed in version 3.26.0 by documenting that the sandbox does not protect against resource exhaustion.
CVE-2026-52890 1 Wekan 1 Wekan 2026-07-16 7.1 High
Wekan is open source kanban built with Meteor. Prior to 9.31, Wekan allows a logged-in board member to insert an attachment document through the /attachments/insert DDP method with attacker-controlled versions.original.path and versions.original.storage fields. The server/permissions/attachments.js insert rule checks only board write access, and FileStoreStrategyFilesystem.getReadStream() in models/lib/fileStoreStrategy.js streams the stored path without a storage-root containment check, allowing arbitrary file reads and denial of service through special files such as /dev/zero. This issue is fixed in version 9.31.
CVE-2026-14684 1 Hdrhistogram 1 Hdrhistogram 2026-07-16 3.3 Low
A flaw has been found in HdrHistogram up to 2.2.2. This affects the function org.HdrHistogram.AbstractHistogram.decodeFromByteBuffer of the file src/main/java/org/HdrHistogram/AbstractHistogram.java. This manipulation of the argument numberOfSignificantValueDigits causes uncontrolled memory allocation. The attack can only be executed locally. The exploit has been published and may be used. The actual existence of this vulnerability is currently in question. This issue is disputed due to the potential lack of crossing of security boundaries and the pre-requisites for a successful attack.
CVE-2026-14683 1 Hdrhistogram 1 Hdrhistogram 2026-07-16 3.3 Low
A vulnerability was detected in HdrHistogram up to 2.2.2. Affected by this issue is the function org.HdrHistogram.AbstractHistogram.decodeFromCompressedByteBuffer of the file src/main/java/org/HdrHistogram/AbstractHistogram.java. The manipulation of the argument lengthOfCompressedContents results in uncontrolled memory allocation. The attack needs to be approached locally. The exploit is now public and may be used. It is still unclear if this vulnerability genuinely exists. This issue is disputed due to the potential lack of crossing of security boundaries and the pre-requisites for a successful attack.
CVE-2026-56375 1 Imagemagick 1 Imagemagick 2026-07-15 3.3 Low
ImageMagick through 7.1.2-18 contains a memory leak vulnerability in the ASHLAR coder when an action fails. Attackers can trigger failed actions to exhaust memory resources and cause denial of service.
CVE-2026-61867 1 Imagemagick 1 Imagemagick 2026-07-15 2.9 Low
ImageMagick before 7.1.2-26 contains a memory leak vulnerability in the TIFF encoder when memory allocation fails. Attackers can trigger allocation failures during TIFF image processing to cause memory exhaustion and denial of service.
CVE-2026-61871 1 Imagemagick 1 Imagemagick 2026-07-15 3.7 Low
ImageMagick before 7.1.2-26 and 6.9.13-51 contains a memory leak in the ICON decoder that occurs when a memory allocation fails. Processing a crafted ICON file that triggers an allocation failure leaks memory, which may lead to a denial of service.
CVE-2026-61449 1 Getgrav 1 Grav 2026-07-15 6.5 Medium
Grav 2.0.1 contains a decompression-bomb size-cap bypass in ZipArchiver and GPM\Installer. The size bound introduced in 2.0.1 sums the uncompressed size declared in each entry's ZIP central-directory header (ZipArchive::statIndex()['size']) and rejects archives exceeding system.gpm.archive.max_uncompressed_size before extraction. Because this declared size is attacker-forgeable and is not cross-checked against the actual inflated stream, a crafted archive declaring tiny per-entry sizes passes the cap while extractTo() writes the real, much larger content, filling disk or exhausting inodes. The archive must be supplied by a package source or admin upload (admin/operator trust). Fixed in 2.0.2. This is an incomplete fix for GHSA-928x-9mpw-8h56.
CVE-2026-12523 1 Cloudflare 1 Quiche 2026-07-15 7.5 High
Summary Cloudflare quiche's HTTP/3 layer was discovered to be vulnerable to resource exhaustion (i.e., memory) by means of specially crafted HTTP/3 frames. Impact HTTP/3 defines multiple frame types to support HTTP message exchanges and connection management. Each frame has a length and a payload whose length depends on the frame type. quiche was found to be vulnerable when parsing some frame types to pre-allocating memory based on the declared length. An attacker would not need to send the number of declared bytes to trigger this issue. In addition, quiche was found to not apply QPACK decompression limits correctly. This could allow an attacker to send specially crafted HEADERS frames that would cause more memory commitment than otherwise advertised by MAX_FIELD_SECTION_SIZE (configured by set_max_field_section_size()). Mitigation: * Users are requested to upgrade to quiche 0.29.3 which is the earliest version containing the fix for this issue. Credits: Disclosed responsibly by Sébastien Féry
CVE-2026-47736 1 Puma 1 Puma 2026-07-15 7.5 High
Puma is a Ruby/Rack web server built for parallelism. From 5.5.0 until 7.2.1 and 8.0.2, when PROXY protocol v1 support is enabled, Puma reads incoming bytes into an internal buffer while waiting for CRLF to determine whether a PROXY v1 line is present, allowing an attacker that continuously sends bytes without CRLF to cause unbounded in-process memory growth and additional CPU cost from repeatedly scanning the growing buffer. This issue is fixed in versions 7.2.1 and 8.0.2.
CVE-2026-44806 1 Microsoft 18 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 15 more 2026-07-14 5.3 Medium
Missing release of memory after effective lifetime in Windows Cryptographic Services allows an unauthorized attacker to deny service over a network.
CVE-2026-49799 1 Microsoft 18 Windows 10 1607, Windows 10 1809, Windows 10 21h2 and 15 more 2026-07-14 6.5 Medium
Uncontrolled resource consumption in Windows Local Security Authority Subsystem Service (LSASS) allows an authorized attacker to deny service over a network.
CVE-2026-58486 1 Hedgedoc 1 Hedgedoc 2026-07-14 N/A
HedgeDoc is an open source, real-time, collaborative, markdown notes application. Prior to version 1.11.0, HedgeDoc was vulnerable to a YAML alias bomb due to unsafe processing of the note frontmatter. HedgeDoc parsed frontmatter with js-yaml.load (js-yaml v3) via @hedgedoc/meta-marked, which resolved YAML anchor aliases. A compact malicious payload could therefore expand into a huge object structure, consuming excessive CPU. This expansion ran on every request to the publish view (/s/<shortid>) and, when placed under the opengraph key, the editor view (/<noteId>). A ten-level alias bomb could block the single Node.js event loop for roughly 235 seconds per request, causing concurrent requests to hang or drop and rendering the instance unavailable (DoS). Because the note was stored in the database, the impact survived process restarts until the note was removed. toobusy-js did not reliably mitigate the worst cases, as the event loop was saturated before the middleware could respond. This issue was fixed in version 1.11.0.
CVE-2026-15690 1 Open62541 1 Open62541 2026-07-14 3.1 Low
A vulnerability was identified in open62541 up to 1.5.5. Affected by this issue is the function responseReadNamespacesArray of the file src/client/ua_client_connect.c of the component Shared Client Library. Such manipulation of the argument Server_NamespaceArray leads to null pointer dereference. The attack can be executed remotely. The attack requires a high level of complexity. The exploitation is known to be difficult. The exploit is publicly available and might be used. The project closed the issue report, stating that this is not the official way to report a security vulnerability.
CVE-2026-59869 2 Nodeca, Redhat 2 Js-yaml, Hummingbird 2026-07-14 7.5 High
js-yaml is a JavaScript YAML parser and dumper. From 3.0.0 before 3.15.0 and from 4.0.0 before 4.3.0, js-yaml can spend quadratic CPU time parsing a document whose size grows only linearly when a chain of mappings uses merge keys where each mapping merges the previous one. This issue is fixed in versions 3.15.0 and 4.3.0.
