Python linting for security hygiene: what flake8, pylint, and bandit actually catch

Bandit maps findings to CWE IDs like CWE-502 and CWE-78, but flake8 and pylint never look for a vulnerability at all — the three tools solve different problems.

The security implications of Node.js worker_threads

Node.js worker_threads share memory across V8 isolates by design — CVE-2025-23083 (CVSS 7.7) shows even the permission model meant to contain them can be bypassed.

How to actually implement TLS correctly in Python

One `verify=False` in a requests call disables both certificate and hostname checks — the same escape hatch PEP 476 tried to close in 2014.

Fuzz testing for AppSec teams: AFL++, libFuzzer, and OSS-Fuzz

OSS-Fuzz has found over 13,000 vulnerabilities since 2016, yet most AppSec teams still treat fuzzing as a research curiosity rather than a pipeline stage.
