## Summary The download service (`download_service.py`) makes HTTP requests using raw `requests.get()` without utilizing the application's SSRF protection (`safe_requests.py`). This can allow attackers to access internal services and attempt to reach cloud provider metadata endpoints (AWS/GCP/Azure), as well as perform internal network reconnaissance, by submitting malicious URLs through the API, depending on the deployment and surrounding controls. **CWE**: CWE-918 (Server-Side Request Forgery) --- ## Details ### Vulnerable Code Location **File**: `src/local_deep_research/research_library/services/download_service.py` The application has proper SSRF protection implemented in `security/safe_requests.py` and `security/ssrf_validator.py`, which blocks: - Loopback addresses (127.0.0.0/8) - Private IP ranges (10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) - AWS metadata endpoint (169.254.169.254) - Link-local addresses However, `download_service.py` bypasses this protection by using ra...

Cybersecurity researchers have discovered two malicious Google Chrome extensions with the same name and published by the same developer that come with capabilities to intercept traffic and capture user credentials. The extensions are advertised as a "multi-location network speed test plug-in" for developers and foreign trade personnel. Both the browser add-ons are available for download as of

This week, Joe laments on 2025, and what we can think of in 2026 in the wild world of cybersecurity.

## Summary S3 Encryption Client for PHP is an open-source client-side encryption library used to facilitate writing and reading encrypted records to S3. When the encrypted data key (EDK) is stored in an "Instruction File" instead of S3's metadata record, the EDK is exposed to an "Invisible Salamanders" attack (https://eprint.iacr.org/2019/016), which could allow the EDK to be replaced with a new key. ## Impact ### Background - Key Commitment There is a cryptographic property whereby under certain conditions, a single ciphertext can be decrypted into 2 different plaintexts by using different encryption keys. To address this issue, strong encryption schemes use what is known as "key commitment", a process by which an encrypted message can only be decrypted by one key; the key used to originally encrypt the message. In older versions of S3EC, when customers are also using a feature called "Instruction File" to store EDKs, key commitment is not implemented because multiple EDK...

This week’s ThreatsDay Bulletin tracks how attackers keep reshaping old tools and finding new angles in familiar systems. Small changes in tactics are stacking up fast, and each one hints at where the next big breach could come from. From shifting infrastructures to clever social hooks, the week’s activity shows just how fluid the threat landscape has become. Here’s the full rundown of what
