| CVE-2026-21441 | 2 Python, Urllib3 | 2 Urllib3, Urllib3 | 2026-09-01 | 7.5 High |
| urllib3 is an HTTP client library for Python. urllib3's streaming API is designed for the efficient handling of large HTTP responses by reading the content in chunks, rather than loading the entire response body into memory at once. urllib3 can perform decoding or decompression based on the HTTP `Content-Encoding` header (e.g., `gzip`, `deflate`, `br`, or `zstd`). When using the streaming API, the library decompresses only the necessary bytes, enabling partial content consumption. Starting in version 1.22 and prior to version 2.6.3, for HTTP redirect responses, the library would read the entire response body to drain the connection and decompress the content unnecessarily. This decompression occurred even before any read methods were called, and configured read limits did not restrict the amount of decompressed data. As a result, there was no safeguard against decompression bombs. A malicious server could exploit this to trigger excessive resource consumption on the client. Applications and libraries are affected when they stream content from untrusted sources by setting `preload_content=False` when they do not disable redirects. Users should upgrade to at least urllib3 v2.6.3, in which the library does not decode content of redirect responses when `preload_content=False`. If upgrading is not immediately possible, disable redirects by setting `redirect=False` for requests to untrusted source. | ||||
| CVE-2026-0994 | 2 Google, Protobuf | 3 Protobuf, Protobuf-python, Protobuf | 2026-09-01 | 7.5 High |
| A denial-of-service (DoS) vulnerability exists in google.protobuf.json_format.ParseDict() in Python, where the max_recursion_depth limit can be bypassed when parsing nested google.protobuf.Any messages. Due to missing recursion depth accounting inside the internal Any-handling logic, an attacker can supply deeply nested Any structures that bypass the intended recursion limit, eventually exhausting Python’s recursion stack and causing a RecursionError. | ||||
| CVE-2025-69223 | 3 Aio-libs, Aio-libs Project, Aiohttp | 4 Aiohttp Session, Aiohttp, Aio-libs and 1 more | 2026-09-01 | 7.5 High |
| AIOHTTP is an asynchronous HTTP client/server framework for asyncio and Python. Versions 3.13.2 and below allow a zip bomb to be used to execute a DoS against the AIOHTTP server. An attacker may be able to send a compressed request that when decompressed by AIOHTTP could exhaust the host's memory. This issue is fixed in version 3.13.3. | ||||
| CVE-2026-56100 | 1 Springblade Project | 1 Springblade | 2026-09-01 | 8.1 High |
| SpringBlade versions from 2.7.3 up to but not including 5.0.0 contain a privilege escalation vulnerability that allows authenticated attackers to create system administrator accounts by sending crafted POST requests to an unprotected internal Feign user-creation endpoint exposed via @RestController without authorization checks. Attackers can exploit the gateway's authentication filter, which only validates JWT parsing without verifying user roles or caller identity, and leverage a hardcoded JWT signing key embedded in publicly available JARs to forge tokens and escalate privileges from a low-privilege user to administrator, enabling cross-tenant data pollution and persistent backdoor access. | ||||
| CVE-2026-81849 | 1 Amazon | 2 Amazon-ssm-agent, Amazon Ssm Agent | 2026-09-01 | 8.8 High |
| Improper limitation of a pathname to a restricted directory in the aws:downloadContent plugin in amazon-ssm-agent before 3.3.4515.0 might allow an authenticated remote user whose ssm:SendCommand permission is restricted to the AWS-DownloadContent document, to write arbitrary files outside the intended download directory with root privileges, via crafted object keys in the S3 source the document is directed to retrieve. This issue may lead to arbitrary code execution as root if specific sensitive files are overwritten. To remediate this issue, customers should upgrade amazon-ssm-agent to version 3.3.4515.0 or later. | ||||
| CVE-2026-55485 | 1 Piccolo-orm | 1 Piccolo | 2026-09-01 | 8.8 High |
| Piccolo Admin is an admin interface and content management system for Python, built on top of Piccolo. Prior to 1.14.0, piccolo_admin/endpoints.py uses superuser_validators to block PUT, PATCH, DELETE, and POST requests by non-superusers but permits GET requests to configured user and session tables, while piccolo_api/session_auth/tables.py exposes SessionsBase.token because the token column is not secret. In deployments that add the Sessions and User tables to create_admin, a non-superuser administrator can call GET /api/tables/sessions/, obtain another user's live session token, replay it as the Cookie id value to impersonate a superuser, and permanently set superuser to true on the attacker's own row. This issue is fixed in version 1.14.0. | ||||
| CVE-2026-77007 | 2 Higheredlab, Wordpress | 2 Hel Online Classroom: Ai-powered Online Classrooms, Wordpress | 2026-09-01 | 7.5 High |
| The HEL Online Classroom: AI-powered Online Classrooms WordPress plugin through 1.0.3 does not perform any authorisation check on one of its REST API routes, allowing unauthenticated users to retrieve its stored settings, including the shared secret used to sign API requests to the connected BigBlueButton server. | ||||
| CVE-2026-18649 | 1 Redhat | 3 Enterprise Linux, Rhel E4s, Rhel Eus | 2026-09-01 | 7.5 High |
| A flaw was found in the GStreamer gst-plugins-good package. The rtph264depay and rtph265depay RTP depayloader elements do not enforce a maximum size limit on the reassembly buffer used during fragmented RTP packet processing. A remote, unauthenticated attacker can send a continuous stream of RTP fragments without ever transmitting an end-of-fragment marker, causing the reassembly buffer to grow without bound until process memory is exhausted. This results in a denial of service through process termination. | ||||
| CVE-2026-17523 | 2 Linux, Redhat | 4 Linux Kernel, Enterprise Linux, Rhel E4s and 1 more | 2026-09-01 | 7.8 High |
| A flaw was found in the Linux kernel in net/can/bcm.c in can: bcm, where an unprivileged local user can exploit this vulnerability to execute arbitrary code within the kernel, which leads to a local privilege escalation (LPE). This allows the attacker to gain root privileges and take full control of the affected system. | ||||
| CVE-2026-19873 | 1 Formfu | 1 Html-formfu | 2026-09-01 | 7.5 High |
| HTML::FormFu versions through 2.08 for Perl allow resource exhaustion via an unbounded repeat count from the query string in Repeatable elements. When a Repeatable element has counter_name set, its process method reads the repeat count from the named query string parameter, checks only that it is a positive integer, and passes it to repeat, which deep-clones the element's child subtree once per iteration. Nothing caps the value, and no attribute lets an application impose a limit. The count is read on every request, before the form decides whether it was submitted, so a plain GET reaches the clone loop with no credentials, no session and no request body. Nesting multiplies: a Repeatable inside a Repeatable takes a counter at each level, so an outer and an inner value of 100 build 10,000 clones. Once the form is submitted, each cloned field's constraints scan the whole element tree in _find_field_value, so cost grows faster than linearly with the count. A single request exhausts memory and CPU. The latest release on CPAN is 2.07, from 2018. Version 2.08 exists only in the git repository. | ||||
| CVE-2026-5121 | 2 Libarchive, Redhat | 17 Libarchive, Ai Inference Server, Discovery and 14 more | 2026-09-01 | 7.5 High |
| A flaw was found in libarchive. On 32-bit systems, an integer overflow vulnerability exists in the zisofs block pointer allocation logic. A remote attacker can exploit this by providing a specially crafted ISO9660 image, which can lead to a heap buffer overflow. This could potentially allow for arbitrary code execution on the affected system. | ||||
| CVE-2026-82475 | 1 Iflytek | 1 Astron-agent | 2026-09-01 | 8.1 High |
| iFlytek astron-agent through 1.1.1 contains an authorization bypass vulnerability in the copyFlow endpoint that fails to validate workflow ownership. Authenticated attackers can enumerate workflow identifiers and overwrite other tenants' workflows or copy private workflows to read their definitions. | ||||
| CVE-2026-82457 | 1 Ncopa | 1 Su-exec | 2026-09-01 | 7.8 High |
| su-exec through 0.3 fails to validate numeric user and group identifiers parsed with strtol before assigning to uid_t and gid_t, allowing truncation of out-of-range values to zero. Attackers can supply large numeric identifiers that truncate to root's identifier, causing su-exec to execute target programs with root privileges instead of intended unprivileged accounts. | ||||
| CVE-2026-58014 | 2 Gnome, Redhat | 7 Glib, Discovery, Enterprise Linux and 4 more | 2026-09-01 | 7.3 High |
| A flaw was found in GLib. An off-by-one error can occur in the g_key_file_get_locale_string_list function in the gkeyfile.c file when loading a key file with an empty value. This flaw can cause an out-of-bounds access of 1 byte or a denial of service when the out-of-bounds access crosses a page boundary. | ||||
| CVE-2026-14164 | 3 Libarchive, Red Hat, Redhat | 12 Libarchive, Enterprise Linux, Discovery and 9 more | 2026-09-01 | 7.5 High |
| A double free issue has been identified in libarchive's RAR5 reader. During parsing of a specially crafted RAR5 archive, the filtered_buf pointer may remain stale after being freed during unpacking state reinitialization. Subsequent processing of another archive entry can trigger a second free of the same memory region, resulting in a double-free condition. Successful exploitation may cause applications using the vulnerable libarchive API to terminate unexpectedly, leading to a denial of service. | ||||
| CVE-2026-55215 | 1 Mariadb-corporation | 1 Mariadb-connector-nodejs | 2026-09-01 | 7.5 High |
| MariaDB Connector/Node.js is used to connect applications developed on Node.js to MariaDB and MySQL databases. Prior to versions 3.3.3, 3.4.6, and 3.5.3, when ssl is enabled without a pinned CA or server certificate, MariaDB Connector/Node.js sends credentials before completing certificate fingerprint validation. In lib/cmd/handshake/auth/handshake.js, a server that selects mysql_clear_password as the initial authentication plugin can receive the password before the post-TLS identity check. In lib/cmd/handshake/authentication.js, an authentication switch can evaluate the previous plugin instead of the requested target plugin, allowing mysql_clear_password to send the credential first. An active man-in-the-middle can present a self-signed certificate, capture the database password, and use it to authenticate directly even though the connector later rejects the server and closes the connection. This issue is fixed in versions 3.3.3, 3.4.6, and 3.5.3. | ||||
| CVE-2026-55065 | 1 Go-vikunja | 1 Vikunja | 2026-09-01 | 8.1 High |
| Vikunja is an open-source self-hosted task management platform. From 0.24.6 until 2.4.0, DELETE /api/v1/projects/:project/views/:view permits an authenticated user to supply a view identifier from another project while authorizing only against an attacker-controlled project identifier. ProjectView.CanDelete in pkg/models/project_view_permissions.go does not establish that the view belongs to the path project, and ProjectView.Delete in pkg/models/project_view.go continues after the scoped project_views delete affects no rows. Its subsequent deletes select task_buckets and task_positions only by project_view_id, allowing cross-tenant destruction of Kanban assignments and ordering while leaving the victim view and tasks intact. This issue is fixed in version 2.4.0. | ||||
| CVE-2026-18899 | 2 Ibm, Langflow | 2 Langflow Oss, Langflow | 2026-09-01 | 7.5 High |
| IBM Langflow OSS 1.0.0 through 1.11.1 could allow a remote attacker to read arbitrary files due to path traversal. | ||||
| CVE-2026-17203 | 1 Ibm | 1 Administration Runtime Expert For I | 2026-09-01 | 7.5 High |
| IBM Administration Runtime Expert for i 1R1M0 could allow a remote authenticated attacker to obtain sensitive information due to improper authentication enforcement. | ||||
| CVE-2026-54100 | 1 Redhat | 5 Openshift, Openshift Container Platform, Openshift For Windows Containers and 2 more | 2026-09-01 | 8.3 High |
| A flaw was found in the Windows Machine Config Operator (WMCO) for Red Hat OpenShift Container Platform. WMCO establishes SSH connections to Windows worker nodes without verifying the remote server host key. An adjacent-network attacker who can intercept or redirect WMCO's SSH session can capture WICD and kubelet bootstrap credentials transferred during node configuration, enabling compromise of Windows node identities in the cluster. | ||||
