JupyterLab: Cross-site scripting (XSS) in JupyterLab via notebook cells pasted from the system clipboard

Description JupyterLab 4.5.0 enabled copying and pasing cells through the system clipboard. The paste path parses clipboard text as cell JSON and inserts the cells without clearing metadata.trusted, so a payload can declare its own output as trusted. JupyterLab does not sanitize a trusted output...

pypdf: Possible long runtimes when generating appearance streams

Impact An attacker who uses this vulnerability can craft a PDF which leads to long runtimes. This requires updating form field values with flattening enabled, which triggers appearance stream generation. Patches This has been fixed in pypdf==6.19.0. Workarounds If you cannot upgrade yet, consider...

brace-expansion: Quadratic-time expansion of the `{a},b}` rewrite causes CPU denial of service

Summary Expanding a,b-shaped input takes time quadratic in the number of literal characters, blocking the event loop. Bash preserves a quirk where a brace group followed by a comma set still expands a,b. The parser implements this by rewriting the string and restarting the scan. Each pass absorbs...

React Router: Open redirect via backslash in <Link> and useNavigate (CVE-2025-68470 bypass)

This is a follow up to CVE-2025-68470. React Router was alerted to certain scenarios in which the fix there was incomplete so there still existed some scenarios where attacker supplied paths passed to navigation mechanisms could result in unexpected external navigations...

DOMPurify: Permanent `ALLOWED_ATTR` pollution via `setConfig()` bypassing the hook clone-guard (incomplete fix of the 3.4.7 hook-pollution patch)

Summary DOMPurify 3.4.7 shipped a security fix "permanent hook pollution" that makes a registered uponSanitizeAttribute hook's mutation of data.allowedAttributes non-persistent — so allowing an attribute for one element does not leak into later sanitize calls. The fix clones ALLOWEDATTR inside...

PHPSpreadsheet has a patch bypass for CVE-2026-34084

Summary CVE-2026-34084 was patched by the helper File::prohibitWrappers. The helper calls parseurl$filename, PHPURLSCHEME and then checks isstring$scheme && strlen$scheme 1 to reject stream wrappers such as phar://, php://, data:// or expect://. The check is not equivalent to "does the path conta...

wasmtime-wasi: WASI path_open(TRUNCATE) bypasses `FilePerms::WRITE` host restriction

Summary In wasmtime-wasi, when a filesystem preopen is given DirPerms::all and FilePerms::READ without FilePerms::WRITE, this wasmtime-wasi enforced access control mechanism can be bypassed by using the wasip2 descriptor.open-at or wasip1 pathopen interfaces by opening a file with...

Vitest browser mode serves unsanitized otelCarrier query parameter as inline script

Summary Vitest browser mode served /vitesttest/ with the otelCarrier query parameter inserted directly into an inline module script. Because this value was treated as JavaScript source rather than data, an attacker could craft a browser-runner URL that executes arbitrary JavaScript in the Vitest...

MLflow: unauthenticated access to certain FastAPI routes

A vulnerability in mlflow/mlflow versions 3.9.0 and earlier allows unauthenticated access to certain FastAPI routes when the server is started with authentication enabled --app-name basic-auth and served via uvicorn ASGI. The FastAPI permission middleware only enforces authentication on /gateway/...

basic-ftp has FTP Command Injection via CRLF

Summary basic-ftp version 5.2.0 allows FTP command injection via CRLF sequences \r\n in file path parameters passed to high-level path APIs such as cd, remove, rename, uploadFrom, downloadTo, list, and removeDir. The library's protectWhitespace helper only handles leading spaces and returns other...

Impact Nonce generation does not use sufficient entropy nor a cryptographically secure pseudorandom source https://github.com/guzzle/oauth-subscriber/blob/0.8.0/src/Oauth1.phpL192. This can leave servers vulnerable to replay attacks when TLS is not used. Patches Upgrade to version 0.8.1 or higher...

Access to Archived Argo Workflows with Fake Token in `client` mode

Summary When using --auth-mode=client, Archived Workflows can be retrieved with a fake or spoofed token via the GET Workflow endpoint: /api/v1/workflows/namespace/name When using --auth-mode=sso, all Archived Workflows can be retrieved with a valid token via the GET Workflow endpoint:...

Next.js Vulnerable to HTTP Request Smuggling

Impact Inconsistent interpretation of a crafted HTTP request meant that requests are treated as both a single request, and two separate requests by Next.js, leading to desynchronized responses. This led to a response queue poisoning vulnerability in the affected Next.js versions. For a request to...

Docker Authentication Bypass

An issue was discovered in Docker Moby before 17.06.0. The Docker engine validated a client TLS certificate using both the configured client CA root certificate and all system roots on non-Windows systems.

In versions of Alist prior to 3.6.0, a user with only file upload permission can bypass the base path restriction by using '... /' to bypass the base path restriction and upload files to an arbitrary path...

Apache Commons BCEL vulnerable to out-of-bounds write

Apache Commons BCEL has a number of APIs that would normally only allow changing specific class characteristics. However, due to an out-of-bounds writing issue, these APIs can be used to produce arbitrary bytecode. This could be abused in applications that pass attacker-controllable data to those...

Unsafe deserialization in com.alibaba:fastjson

The package com.alibaba:fastjson before 1.2.83 is vulnerable to Deserialization of Untrusted Data by bypassing the default autoType shutdown restrictions, which is possible under certain conditions. Exploiting this vulnerability allows attacking remote servers. Workaround: If upgrading is not...

Elasticsearch privilege escalation

A flaw was discovered in Elasticsearch 7.17.0’s upgrade assistant, in which upgrading from version 6.x to 7.x would disable the in-built protections on the security index, allowing authenticated users with “” index permissions access to this index. Users running a cluster on an affected version...

Apache Cassandra vulnerable to Code Injection due to unsafe configuration

When running Apache Cassandra with the following configuration: enableuserdefinedfunctions: true enablescripteduserdefinedfunctions: true enableuserdefinedfunctionsthreads: false it is possible for an attacker to execute arbitrary code on the host. The attacker would need to have enough permissio...

HTTP request smuggling in netty

Impact Netty currently just skips control chars when these are present at the beginning / end of the header name. We should better fail fast as these are not allowed by the spec and could lead to HTTP request smuggling. Failing to do the validation might cause netty to "sanitize" header names...

Incorrect Authorization with specially crafted requests

Envoy, which Pomerium is based on, contains two authorization related vulnerabilities: - CVE-2021-32777: incorrectly transform a URL containing a fragment element, causing a mismatch in path-prefix based authorization decisions. - CVE-2021-32779: incorrectly handle duplicate headers, dropping all...

Incorrect Authorization in serverless-offline

Serverless Offline 8.0.0 returns a 403 HTTP status code for a route that has a trailing / character, which might cause a developer to implement incorrect access control, because the actual behavior within the Amazon AWS environment is a 200 HTTP status code i.e., possibly greater than expected...

Missing Authorization in Apache Airflow

If remote logging is not used, the worker in the case of CeleryExecutor or the scheduler in the case of LocalExecutor runs a Flask logging server and is listening on a specific port and also binds on 0.0.0.0 by default.
