CVE Severity Published▾ Status Exploitation Description
CVE-2026-35250 Low 2026-04-21 Not applicable No public exploit Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is 7.2.6. Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. Successful attacks of this vulnerability can result in unauthorized ability to cause a partial denial of service (partial DOS) of Oracle VM VirtualBox. CVSS 3.1 Base Score 2.3 (Availability impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L).
CVE-2026-35249 Low 2026-04-21 Not applicable No public exploit Vulnerability in the Oracle VM VirtualBox product of Oracle Virtualization (component: Core). The supported version that is affected is 7.2.6. Easily exploitable vulnerability allows high privileged attacker with logon to the infrastructure where Oracle VM VirtualBox executes to compromise Oracle VM VirtualBox. While the vulnerability is in Oracle VM VirtualBox, attacks may significantly impact additional products (scope change). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle VM VirtualBox accessible data. CVSS 3.1 Base Score 3.2 (Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:C/C:N/I:L/A:N).
CVE-2026-34312 Low 2026-04-21 Not applicable No public exploit Vulnerability in the RDBMS component of Oracle Database Server. Supported versions that are affected are 19.3-19.30. Easily exploitable vulnerability allows high privileged attacker having Row Access Method privilege with network access via multiple protocols to compromise RDBMS. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized read access to a subset of RDBMS accessible data. CVSS 3.1 Base Score 2.4 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:L/I:N/A:N).
CVE-2026-22001 Low 2026-04-21 Not applicable No public exploit Vulnerability in the MySQL Server product of Oracle MySQL (component: Server: Information Schema). Supported versions that are affected are 8.0.0-8.0.45, 8.4.0-8.4.8 and 9.0.0-9.6.0. 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 read access to a subset of MySQL Server accessible data. CVSS 3.1 Base Score 2.7 (Confidentiality impacts). CVSS Vector: (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:N/A:N).
CVE-2026-24515 Low 2026-01-23 Not applicable No public exploit In libexpat before 2.7.4, XML_ExternalEntityParserCreate does not copy unknown encoding handler user data.
CVE-2025-15224 Low 2026-01-08 Not applicable Proof of concept only When doing SSH-based transfers using either SCP or SFTP, and asked to do public key authentication, curl would wrongly still ask and authenticate using a locally running SSH agent.
CVE-2025-69230 Low 2026-01-06 Not applicable No public exploit AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. In versions 3.13.2 and below, reading multiple invalid cookies can lead to a logging storm. If the cookies attribute is accessed in an application, then an attacker may be able to trigger a storm of warning-level logs using a specially crafted Cookie header. This issue is fixed in 3.13.3.
CVE-2025-69225 Low 2026-01-06 Not applicable No public exploit AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below contain parser logic which allows non-ASCII decimals to be present in the Range header. There is no known impact, but there is the possibility that there's a method to exploit a request smuggling vulnerability. This issue is fixed in version 3.13.3.
CVE-2025-61984 Low 2025-10-06 Not applicable Proof of concept only ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted sources are the command line and %-sequence expansion of a configuration file. (A configuration file that provides a complete literal username is not categorized as an untrusted source.)
CVE-2025-8961 Low 2025-08-14 Not applicable Proof of concept only A weakness has been identified in LibTIFF 4.7.0. This affects the function main of the file tiffcrop.c of the component tiffcrop. Executing manipulation can lead to memory corruption. The attack can only be executed locally. The exploit has been made available to the public and could be exploited.
CVE-2025-8176 Low 2025-07-26 Not applicable Proof of concept only A vulnerability was found in LibTIFF up to 4.7.0. It has been declared as critical. This vulnerability affects the function get_histogram of the file tools/tiffmedian.c. The manipulation leads to use after free. The attack needs to be approached locally. The exploit has been disclosed to the public and may be used. The patch is identified as fe10872e53efba9cc36c66ac4ab3b41a839d5172. It is recommended to apply a patch to fix this issue.
CVE-2025-4878 Low 2025-07-22 Not applicable No public exploit A vulnerability was found in libssh, where an uninitialized variable exists under certain conditions in the privatekey_from_file() function. This flaw can be triggered if the file specified by the filename doesn't exist and may lead to possible signing failures or heap corruption.
CVE-2025-53643 Low 2025-07-14 Not applicable No public exploit AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Prior to version 3.12.14, the Python parser is vulnerable to a request smuggling vulnerability due to not parsing trailer sections of an HTTP request. If a pure Python version of aiohttp is installed (i.e. without the usual C extensions) or AIOHTTP_NO_EXTENSIONS is enabled, then an attacker may be able to execute a request smuggling attack to bypass certain firewalls or proxy protections. Version 3.12.14 contains a patch for this issue.
