CVE-2026-26233 1 Mattermost 2 Mattermost, Mattermost Server 2026-03-27 4.3 Medium
Mattermost versions 11.4.x <= 11.4.0, 11.3.x <= 11.3.1, 11.2.x <= 11.2.3, 10.11.x <= 10.11.11 fail to rate limit login requests which allows unauthenticated remote attackers to cause denial of service (server crash and restart) via HTTP/2 single packet attack with 100+ parallel login requests.. Mattermost Advisory ID: MMSA-2025-00566
CVE-2026-21720 1 Grafana 2 Grafana, Grafana Enterprise 2026-03-27 7.5 High
Every uncached /avatar/:hash request spawns a goroutine that refreshes the Gravatar image. If the refresh sits in the 10-slot worker queue longer than three seconds, the handler times out and stops listening for the result, so that goroutine blocks forever trying to send on an unbuffered channel. Sustained traffic with random hashes keeps tripping this timeout, so goroutine count grows linearly, eventually exhausting memory and causing Grafana to crash on some systems.
CVE-2023-5371 1 Wireshark 1 Wireshark 2026-03-27 5.3 Medium
RTPS dissector memory leak in Wireshark 4.0.0 to 4.0.8 and 3.6.0 to 3.6.16 allows denial of service via packet injection or crafted capture file
CVE-2023-4513 1 Wireshark 1 Wireshark 2026-03-27 5.3 Medium
BT SDP dissector memory leak in Wireshark 4.0.0 to 4.0.7 and 3.6.0 to 3.6.15 allows denial of service via packet injection or crafted capture file
CVE-2026-28874 1 Apple 3 Ios And Ipados, Ipados, Iphone Os 2026-03-27 7.5 High
The issue was addressed with improved checks. This issue is fixed in iOS 26.4 and iPadOS 26.4. A remote attacker may cause an unexpected app termination.
CVE-2026-3988 1 Gitlab 1 Gitlab 2026-03-27 7.5 High
GitLab has remediated an issue in GitLab CE/EE affecting all versions from 18.5 before 18.8.7, 18.9 before 18.9.3, and 18.10 before 18.10.1 that could have allowed an unauthenticated user to cause a denial of service by making the GitLab instance unresponsive due to improper input validation in GraphQL request processing.
CVE-2026-4247 1 Freebsd 1 Freebsd 2026-03-27 7.5 High
When a challenge ACK is to be sent tcp_respond() constructs and sends the challenge ACK and consumes the mbuf that is passed in. When no challenge ACK should be sent the function returns and leaks the mbuf. If an attacker is either on path with an established TCP connection, or can themselves establish a TCP connection, to an affected FreeBSD machine, they can easily craft and send packets which meet the challenge ACK criteria and cause the FreeBSD host to leak an mbuf for each crafted packet in excess of the configured rate limit settings i.e. with default settings, crafted packets in excess of the first 5 sent within a 1s period will leak an mbuf. Technically, off-path attackers can also exploit this problem by guessing the IP addresses, TCP port numbers and in some cases the sequence numbers of established connections and spoofing packets towards a FreeBSD machine, but this is harder to do effectively.
CVE-2026-3116 1 Mattermost 1 Mattermost 2026-03-27 4.9 Medium
Mattermost Plugins versions <=11.4 11.0.4 11.1.3 11.3.2 10.11.11.0 fail to validate incoming request size which allows an authenticated attacker to cause service disruption via the webhook endpoint. Mattermost Advisory ID: MMSA-2026-00589
CVE-2026-3114 1 Mattermost 1 Mattermost 2026-03-27 6.5 Medium
Mattermost versions 11.4.x <= 11.4.0, 11.3.x <= 11.3.1, 11.2.x <= 11.2.3, 10.11.x <= 10.11.11 fail to validate decompressed archive entry sizes during file extraction which allows authenticated users with file upload permissions to cause a denial of service via crafted zip archives containing highly compressed entries (zip bombs) that exhaust server memory.. Mattermost Advisory ID: MMSA-2026-00598
CVE-2026-33856 1 Molotovcherry 1 Android-imagemagick7 2026-03-27 7.5 High
Missing Release of Memory after Effective Lifetime vulnerability in MolotovCherry Android-ImageMagick7.This issue affects Android-ImageMagick7: before 7.1.2-11.
CVE-2026-33852 1 Molotovcherry 1 Android-imagemagick7 2026-03-27 7.5 High
Missing Release of Memory after Effective Lifetime vulnerability in MolotovCherry Android-ImageMagick7.This issue affects Android-ImageMagick7: before 7.1.2-11.
CVE-2025-25207 1 Redhat 1 Connectivity Link 2026-03-26 5.7 Medium
The Authorino service in the Red Hat Connectivity Link is the authorization service for zero trust API security. Authorino allows the users with developer persona to add callbacks to be executed to HTTP endpoints once the authorization process is completed. It was found that an attacker with developer persona access can add a large number of those callbacks to be executed by Authorino and as the authentication policy is enforced by a single instance of the service, this leada to a Denial of Service in Authorino while processing the post-authorization callbacks.
CVE-2025-25208 1 Redhat 1 Connectivity Link 2026-03-26 5.7 Medium
A Developer persona can bring down the Authorino service, preventing the evaluation of all AuthPolicies on the cluster
CVE-2026-20012 2026-03-26 8.6 High
A vulnerability in the Internet Key Exchange version 2 (IKEv2) feature of Cisco IOS Software, Cisco IOS XE Software, Cisco Secure Firewall Adaptive Security Appliance (ASA) Software, and Cisco Secure Firewall Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to trigger a memory leak, resulting in a denial of service (DoS) condition on an affected device. This vulnerability is due to improper parsing of IKEv2 packets. An attacker could exploit this vulnerability by sending crafted IKEv2 packets to an affected device. A successful exploit of Cisco IOS Software and IOS XE Software could allow the attacker to cause the affected device to reload, resulting in a DoS condition. A successful exploit of Cisco Secure Firewall ASA Software and Secure FTD Software could allow the attacker to partially exhaust system memory, resulting in system instability, such as the inability to establish new IKEv2 VPN sessions. A manual reboot of the device is required to recover from this condition.
CVE-2026-20084 1 Cisco 1 Ios Xe Software 2026-03-26 8.6 High
A vulnerability in the DHCP snooping feature of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause BOOTP packets to be forwarded between VLANs, resulting in a denial of service (DoS) condition. This vulnerability is due to improper handling of BOOTP packets on Cisco Catalyst 9000 Series Switches. An attacker could exploit this vulnerability by sending BOOTP request packets to an affected device. A successful exploit could allow an attacker to forward BOOTP packets from one VLAN to another, resulting in BOOTP VLAN leakage and potentially leading to high CPU utilization. This makes the device unreachable (either through console or remote management) and unable to forward traffic, resulting in a DoS condition. Note: This vulnerability can be exploited with either unicast or broadcast BOOTP packets. There are workarounds that address this vulnerability.
CVE-2026-33287 1 Harttle 1 Liquidjs 2026-03-26 7.5 High
LiquidJS is a Shopify / GitHub Pages compatible template engine in pure JavaScript. Prior to version 10.25.1, the `replace_first` filter in LiquidJS uses JavaScript's `String.prototype.replace()` which interprets `$&` as a back reference to the matched substring. The filter only charges `memoryLimit` for the input string length, not the amplified output. An attacker can achieve exponential memory amplification (up to 625,000:1) while staying within the `memoryLimit` budget, leading to denial of service. Version 10.25.1 patches the issue.
CVE-2024-1394 1 Redhat 23 Ansible Automation Platform, Ansible Automation Platform Developer, Ansible Automation Platform Inside and 20 more 2026-03-26 7.5 High
A memory leak flaw was found in Golang in the RSA encrypting/decrypting code, which might lead to a resource exhaustion vulnerability using attacker-controlled inputs​. The memory leak happens in github.com/golang-fips/openssl/openssl/rsa.go#L113. The objects leaked are pkey​ and ctx​. That function uses named return parameters to free pkey​ and ctx​ if there is an error initializing the context or setting the different properties. All return statements related to error cases follow the "return nil, nil, fail(...)" pattern, meaning that pkey​ and ctx​ will be nil inside the deferred function that should free them.

CVE-2026-4727 1 Mozilla 2 Firefox, Thunderbird 2026-03-26 7.5 High
Denial-of-service in the Libraries component in NSS. This vulnerability affects Firefox < 149 and Thunderbird < 149.
