Multer vulnerable to Denial of Service via incomplete cleanup of aborted uploads

Impact A vulnerability in Multer allows an attacker to trigger a Denial of Service DoS by aborting or sending malformed multipart uploads, causing orphaned partial files to accumulate on disk when using diskStorage. Patches Users should upgrade to 2.2.0, 3.0.0-alpha.2 or higher Workarounds None...

GHSA-FG94-H982-F3MM Claude Code: Out-of-Band Data Exfiltration via Pre-Approved HuggingFace Domain in WebFetch

Because the hostname huggingface.co was pre-approved as a bare hostname for the WebFetch tool, any path on that domain—including attacker-controlled model repositories—was auto-approved without a permission prompt or being subject to --allowedTools restrictions. An attacker able to inject untrust...

CVE-2026-53870 Hermes Agent < 0.16.0 - Sensitive File Permission Vulnerability in Store Files

Hermes Agent before 0.16.0 creates responsestore.db and webhooksubscriptions.json with world-readable permissions mode 0o644, exposing conversation history and HMAC secrets to local users. Attackers with local filesystem access can read these files directly to obtain sensitive data including...

CVE-2026-53872

picklescan before 0.0.35 contains an unsafe pickle deserialization vulnerability allowing unauthenticated attackers to read arbitrary server files by chaining io.FileIO and urllib.request.urlopen. Attackers can bypass RCE-focused blocklists to exfiltrate sensitive data like /etc/passwd to externa...

CVE-2026-53873

The CVE-2026-53873 vulnerability affects picklescan prior to 1.0.4, where an incomplete blocklist for the profile module fails to block module-level profile.run(), enabling arbitrary code execution via exec() through crafted pickle files. Attackers can craft malicious pickles calling profile.run(...
