CVE-2026-123814

pyLoad WindowsPhoneNotify addon: non-admin SETTINGS user triggers SSRF via unguarded http.client notification host

pyLoad is a free and open-source download manager written in Python. Prior to 0.5.0b3.dev102, an authenticated non-admin user with the SETTINGS permission can configure WindowsPhoneNotify through /json/save_config by setting pushurl, pushid, and enabled. WindowsPhoneNotify.send in src/pyload/plugins/addons/WindowsPhoneNotify.py then uses http.client.HTTPConnection without pyLoad's pycurl destination validation. When a download completes, the global notification event causes a blind POST from the pyLoad server to the attacker-selected internal host, port, and path. The response is not returned, but the request can probe internal services, reach cloud metadata endpoints, or trigger state-changing internal HTTP endpoints. This issue is fixed in version 0.5.0b3.dev102.

CVE-2026-123809

Dynatrace MCP Server: Workflow template injection via create_workflow_for_notification

Dynatrace MCP Server is an MCP server for Dynatrace Observability. Prior to 2.0.0, the create_workflow_for_notification tool inserts the caller-controlled teamName, problemType, and channel values into a Dynatrace workflow without neutralizing Jinja2 expressions. A caller can place template expressions such as event() in those values, and the workflow engine evaluates them when the persistent workflow runs. When the workflow has a valid Slack connector, the resulting Slack action can disclose event or tenant metadata to an attacker-selected channel; the shipped placeholder connection does not deliver messages by itself. The workflow remains in the tenant after the MCP session and credentials are gone. The isPrivate option defaults to false, making the created workflow tenant-visible unless the caller changes it. Exploitation requires either an MCP prompt-injection path or an operator approving a prompt that displays the template fragment literally. This issue is fixed in version 2.0.0.

CVE-2026-123371

compose-lint: A `.compose-lint.yml` symlinked outside the project is read, and a parse error quotes part of the target

compose-lint is a Docker Compose security linter that identifies dangerous misconfigurations before deployment. From 0.2.0 until 0.32.0, compose-lint automatically follows a .compose-lint.yml policy-file symbolic link outside the project and includes part of the target line when that external file fails YAML parsing. A pull request can point the policy file at a runner credential file, causing about 30 characters around an attacker-uncontrolled parse position to appear in standard error, JSON errors, and SARIF tool execution notifications uploaded by the GitHub Action. The run exits with an error and the attacker cannot select the exact disclosed line, but public logs or Code Scanning output can reveal part of the target. This issue is fixed in version 0.32.0.

CVE-2026-123367

ThorVG: Heap buffer overflow (OOB write) in bundled jpgd JPEG decoder

Thor Vector Graphics (ThorVG) is a production-ready vector graphics engine. Prior to 1.1.2, the bundled jpgd JPEG decoder accepts duplicate component selectors in an SOS scan header, causing each duplicate to increase m_blocks_per_mcu without checking the buffers sized from the frame components. A crafted grayscale JPEG can repeat its component in the SOS header, causing decode paths in src/loaders/jpg/tvgJpgd.cpp to write beyond heap buffers sized for one component. The issue is reachable through direct JPEG decoding and through JPEG images embedded in Lottie content, and confirmed impact is memory corruption followed by a process crash. This issue is fixed in version 1.1.2.

CVE-2026-123033

middlewared: middlewared: Authentication bypass via improper HA heartbeat origin check

Authentication bypass in the HA heartbeat origin check in middlewared in TrueNAS SCALE before 25.10.8 (and in release trains before their respective fixes) allows an attacker on the same network segment to achieve unauthenticated full-administrator API access and execute commands as root. middlewared registers the HA peer-authentication hook (ha_permission) unconditionally, with no failover-licence or heartbeat-interface check. An unauthenticated connection whose TCP peer address is a hardcoded HA heartbeat address (169.254.10.1 or 169.254.10.2) and whose peer port is <= 1024 is granted a node credential that is authorized for every API method and treated as full administrator. Both conditions are properties of the attacker's own socket, and thus an attacker on the same layer-2 segment satisfies them without forging anything. The hook is present on non-HA, unlicensed, single-node Community Edition installations. The fix additionally requires that the connection terminate on the HA heartbeat listener (a local address/port the attacker cannot control).
