### Impact This impacts users of Shescape on Unix systems that explicitly configure `shell` to Dash, or `true` when the default shell is Dash, using the `escape` and `escapeAll` APIs in assignments prefixed to a command. An attacker may be able to obtain the location of the home directory and, depending on how it is used, change the location on which a command operates in unexpected ways. ```javascript import * as cp from "node:child_process"; import { Shescape } from "shescape"; // 1. Prere

### Impact This impacts users of Shescape on Windows that explicitly configure `shell` to CMD, or `true` with the default shell being CMD, using the `escape` and `escapeAll` APIs. An attacker may be able to achieve shell injection depending on the original command. ```javascript import * as cp from "node:child_process"; import { Shescape } from "shescape"; // 1. Prerequisites const options = { shell: "cmd.exe", // Or shell: true, // Only if the default shell is CMD }; // 2. Payl

### Impact This impacts users of Shescape on Unix systems that explicitly configure `shell` to Zsh, or `true` when the default shell is Zsh, using the `escape` and `escapeAll`. The Zsh options `EXTENDED_GLOB` and `MAGIC_EQUAL_SUBST` exacerbate the problem. In certain case, an attacker can leverage home directory expansion and extended glob syntax to obtain lists of files and directories on the system. Depending on what the command does, this may be used to leak more information. #### Without

## Summary The AWS API MCP Server is an open source Model Context Protocol (MCP) server that enables AI assistants to interact with AWS services and resources through AWS CLI commands. It provides programmatic access to manage your AWS infrastructure while maintaining proper security controls. It includes an optional, user-configured security policy that can deny or gate specific AWS operations. An issue exists where, if the data used to enforce this policy fails to initialize at server startup,

### Summary An authorization bypass vulnerability exists in the file sharing mechanism of `Openlist`. Due to a flawed, non-separator-aware path validation check, an authenticated user can create share links for files outside their restricted base directory. This allows an attacker to bypass tenant/user isolation and gain unauthorized read access to arbitrary files within the system. ### Details When a user attempts to create or update a file share, the application must verify that the requested

### Summary An authorization bypass and information disclosure vulnerability exists in the search API of `Openlist`. Due to a non-separator-aware path check and unfiltered backend counting, a low-privileged user can bypass their assigned `BasePath` restrictions to discover and access metadata of files residing in unauthorized sibling directories. ### Details This vulnerability stems from two combined logic flaws when the `bleve` search engine is utilized: 1. **Insecure Path Prefix Validation:*

### Summary The `/api/fs/batch_rename` handler validates and authorizes only the requested source directory. It rejects path separators in `new_name`, but it does not validate `src_name`. The handler concatenates `src_dir` and attacker-controlled `src_name`, then passes the result to the filesystem rename layer, where the path is normalized. An authenticated user with rename permission can set `src_name` to traversal segments such as `../../ab/secret.txt`. When the user's base path is `/team/a

## Summary `http4s-blaze-server` aggregates the fragments of an incoming WebSocket message with no limit on total size or fragment count. A client that completes a WebSocket handshake can send an unterminated fragmented message and drive unbounded heap growth in the server JVM, resulting in denial of service via `OutOfMemoryError`. ## Impact Any http4s application serving WebSocket routes over `BlazeServerBuilder` is affected; no non-default configuration is required, and `maxWebSocketBufferS

### Summary blaze-server can merge HTTP/1.1 chunked-body trailer fields into `Request.headers`. Because trailer fields are attacker-controlled, an unauthenticated remote client can inject arbitrary header names/values (e.g. `X-Forwarded-For`, internal-auth headers) that a fronting proxy sanitized from the request-header section, bypassing header-based trust decisions in the application. ### Impact Any http4s application using `BlazeServerBuilder` over HTTP/1.1 whose routes or middleware t

### Summary Five independent HTTP/1.1 conformance laxities in blaze's hand-written Java parser (`http/src/main/java/org/http4s/blaze/http/parser/`) cause request-boundary disagreement with a stricter intermediary. All are reachable from a default `BlazeServerBuilder` with no non-default configuration. ### Impact Actual exploitability depends on the fronting proxy — a boundary disagreement requires a *pair* of parsers that disagree. Where the proxy forwards the malformed bytes and derives a di

## Preface Poweradmin maps OIDC identities into local users through `oidc_user_links.oidc_subject` plus `provider_id`. In the MySQL schema, the OIDC link table explicitly uses `utf8mb4_unicode_ci`, which is case-insensitive and accent-insensitive. OIDC `sub` is a stable external subject identifier and should be matched byte-for-byte within the issuer/provider scope. The confirmed local PoC used two different OIDC users: - Victim subject: `victim-login` - Attacker subject: `victím-login` (`í`,

## Affected software - Product: Poweradmin (web front-end for PowerDNS) - Version tested: master, commit 7f28c3a97 (also reachable in the 4.x release line — the record-edit code is the same) - Component: record editing (web UI) - Vulnerability type: Broken Access Control / Insecure Direct Object Reference ## Severity Any authenticated user who owns at least one zone can tamper with records in every other zone on the server. In a shared/multi-tenant Poweradmin install this is effectively a cro

### Summary The REST API user-update endpoint (`PUT/PATCH /api/v2/users/{id}` and the V1 equivalent) does not enforce two authorization rules that the web interface enforces. A user who holds the `user_edit_others` permission but is not a superuser can: 1. edit user accounts that belong to a superuser, and 2. set the password of any account, even without the `user_passwd_edit_others` permission. Because of this, a non-admin "user manager" role can send a single API request that changes the ad

## Summary The forced password-change flow, triggered when the stored password is still the default (`admin`), does not verify that the password submitted by the client actually matches the current password. Any non-empty value in `pheditor_password` is enough to reach the password-change form, and submitting `pheditor_new_password` / `pheditor_confirm_password` in the same request is enough to set an arbitrary new password and obtain an authenticated session — without ever proving knowledge of

### Summary `expand()` bounds the *number* of results it produces (the `max` option, `100_000` by default) but not their *length*. By chaining many brace groups, an attacker keeps the result count under `max` while making every result grow with the number of groups. Building `max` long results — plus the intermediate arrays combined at each brace group — exhausts memory and crashes the Node process with an **uncatchable** out-of-memory error. `try/catch` around `expand()` does not help: the fat

## Summary SwiftNIO HTTP/2 was missing validation on inbound HEADERS frames that let CR, LF, NUL, SP and other control characters reach an HTTP/1.1 backend through NIOHTTP2's HTTP/2-to-HTTP/1 codec, enabling HTTP request smuggling or response splitting. ## Impact Two related gaps in inbound header validation, against any application using HTTP2ToHTTP1Codec (or HTTP2FramePayloadToHTTP1Codec) to front an HTTP/1.1 backend: Regular header field values were only checked against a forbidden-name l

## Summary `sm-crypto` (npm package **0.4.0**, the latest release, published 2026-01-20) generates SM2 private keys and signing ephemeral scalars from a single module-wide RNG instance (`src/sm2/utils.js`: `const rng = new SecureRandom()`). `SecureRandom` is jsbn's PRNG, which seeds an **ARC4** stream from `window.crypto.getRandomValues` when available. **In Node.js — sm-crypto's primary runtime — `window` is `undefined`, so the CSPRNG branch is skipped** and the seed pool is instead filled fro

## Summary Cloudreve exposes two admin node test endpoints under the `Admin.Read` OAuth scope. These endpoints accept attacker-controlled node definitions and cause Cloudreve to make outbound server-side network requests. This allows an OAuth client authorized only for `Admin.Read` to trigger operational network actions that should require `Admin.Write`. ## Impact An attacker who obtains an admin-authorized OAuth token with `Admin.Read` but not `Admin.Write` can make the Cloudreve server conn
