Sep 29, 2026In wsl-pro-service before 0.1.19ubuntu3, the service component which runs as root inside each WSL instance attaches the instance to Ubuntu Pro by executing the CVE-2026-102371 · Other software · Canonical · reported by security@ubuntu.comMedium 5.7
In wsl-pro-service before 0.1.19ubuntu3, the service component which runs as root inside each WSL instance attaches the instance to Ubuntu Pro by executing the pro client with the Ubuntu Pro token passed as a command-line argument (pro attach <token>). On systems where /proc is mounted without process-hiding mitigations (such as hidepid), which is the default in WSL, an unprivileged local user or process in the same WSL instance can read the token from /proc/<pid>/cmdline while the attach process is running. The leaked token could then be used to attach other machines to the victim's Ubuntu Pro subscription and gain unauthorized access to Ubuntu Pro services.

Sep 29, 2026Apache Polaris allows an authenticated principal with permission to create or update Iceberg table properties to set FileIO client settings such as s3.endpoint CVE-2026-97395 · Websites & servers · Apache Software Foundation · reported by security@apache.orgHigh 8.1
Apache Polaris allows an authenticated principal with permission to create or update Iceberg table properties to set FileIO client settings such as s3.endpoint in table metadata. In versions < 1.8.0, when Polaris performs server-side Iceberg operations, including commits and purges, it may use those settings to construct its (server-side) FileIO client. If the catalog storage configuration does not override the endpoint, Polaris can send storage requests to a host chosen by the table writer, using credentials scoped to the operation. This can redirect server-side storage traffic and expose request authentication material to the chosen endpoint. Deployments are affected when table writers are not trusted to configure server-side storage endpoints.

Sep 29, 2026An improper authorization vulnerability exists in the handling of sub-workflow tasks.CVE-2026-81569 · Websites & servers · Apache Software Foundation · reported by security@apache.orgMedium 4.3
An improper authorization vulnerability exists in the handling of sub-workflow tasks. An authenticated user who does not have permission to access a target project can reference and invoke a workflow belonging to that project through a sub-workflow task. The system does not properly verify whether the user has permission to execute the referenced workflow or access its project. As a result, the user can bypass project-level authorization controls and cause workflows in unauthorized projects to be executed. Successful exploitation may allow unauthorized execution of workflow tasks and access to the resources or data available to the target workflow. This issue affects Apache DolphinScheduler: before 3.4.3. Users are recommended to upgrade to version 3.4.3, which fixes the issue.

Sep 29, 2026An authentication bypass vulnerability exists in the protection of Actuator endpoints.CVE-2026-78214 · Websites & servers · Apache Software Foundation · reported by security@apache.orgMedium 5.3
An authentication bypass vulnerability exists in the protection of Actuator endpoints. The application determines whether authentication is required by matching the incoming request path against protected Actuator paths. By sending a specially crafted request containing a percent-encoded path, a remote unauthenticated attacker can cause the security check to fail to recognize the request as targeting a protected endpoint. As a result, the attacker may bypass authentication and access otherwise restricted Actuator endpoints. Successful exploitation may expose operational or configuration information and, depending on the enabled endpoints and application configuration, allow access to sensitive management functionality. This issue affects Apache DolphinScheduler: before 3.4.3. Users are recommended to upgrade to version 3.4.3, which fixes the issue.

A missing authorization vulnerability exists in the `query-dynamic-sub-workflows` API of Apache DolphinScheduler. The API does not properly verify whether the authenticated user has permission to access the workflows being queried. An authenticated user who does not have permission to access a specific project can invoke the API with parameters referencing workflows belonging to that project and retrieve workflow information. This allows users to access workflow data outside their authorized project scope, resulting in unauthorized information disclosure. This issue affects Apache DolphinScheduler: from 3.2.0 before 3.4.3. Users are recommended to upgrade to version 3.4.3, which fixes the issue.

The decoder in `readFromDataView` in lib0 before 0.2.119 can be tricked into reading more than it should from a buffer.

A missing bounds check in the binary decoder in lib0, versions 0.2.1-0.2.117 and earlier and 1.0.0-rc.32 and earlier, lets any unauthenticated remote peer read adjacent process memory and receive it back. `readUint8Array` never compares the wire-supplied length against the decoder's own view, so one over-long length prefix returns whatever the host process allocated next: other tenants' document content, personal data, and live bearer session tokens**, recovered in full and at will. An attacker who can supply bytes to a lib0 decoder which means any peer that can open a socket, including before authentication reads adjacent process memory and, where the consumer echoes, stores or re-serves the decoded value, receives it back. This is patched in version 0.2.118 and 1.0.0-rc.33.

In the Linux kernel, the following vulnerability has been resolved: KVM: x86/mmu: Check write tracking in all address spaces kvm_gfn_is_write_tracked() checks only the supplied memslot, but page tracking is per-address-space and shadow pages are shared across all address spaces. With SMM, a GFN can therefore be write-tracked in one address space and appear untracked through the other. Check the supplied slot first, then the slot for the other address space. This ensures all callers honor write tracking regardless of the active address space. In particular, it prevents mmu_try_to_unsync_pages() from marking an upper-level shadow page unsync and eventually triggering the BUG in pte_list_remove().

The scriptPath parameter is incorporated into a /bin/sh -c command without sufficient neutralization of shell metacharacters, allowing shell command substitution and execution. An authenticated user can exploit this behavior by creating a resource whose filename contains shell command substitution syntax, such as $(...), and subsequently supplying the resulting path to the Alert Script plugin's /test-send endpoint. When the alert script is executed, the shell interprets the injected command, resulting in arbitrary command execution with the privileges of the DolphinScheduler service process.

PyPy before versions 3.11.16 and 3.12.14 contains a use-after-free vulnerability in the pyexpat module's ExternalEntityParserCreate function that allows attackers to corrupt memory by supplying a crafted XML document to applications that create external-entity sub-parsers without retaining a reference to the parent parser. The child parser retains a raw C back-pointer to the parent parser struct while PyPy's tracing garbage collector can free the parent's C struct, causing bundled libexpat to dereference the freed pointer on every parsed token, producing memory corruption.

Where this comes from: the exploited list is CISA’s Known Exploited Vulnerabilities catalog. Everything else is the whole National Vulnerability Database, where each record is published by the team that found the bug (Wordfence, Patchstack, WPScan, the vendors themselves and others); we show who. Exploit odds are FIRST’s EPSS, updated daily. Titles and categories are ours, so check the linked record before acting on a detail. For a write-up of the big ones, see our advisories. Every vendor, and every WordPress plugin and theme with a recorded flaw, also has its own page. All of it is free to reuse as JSON, CSV or RSS.
