This vulnerability allows remote attackers to execute arbitrary code on affected installations of Hugging Face Diffusers. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the parsing of checkpoints. The issue results from the lack of proper validation of user-supplied data, which can result in deserialization of untrusted data. An attacker can leverage this vulnerability to execute code in the context of the current process.

CRITICAL Alerts (Immediate Action Required)
1. u/cap-js ecosystem compromise (CVE-2026-46421)
Threat: Compromised versions of u/cap-js/sqlite, u/cap-js/postgres, and u/cap-js/db-service were published to harvest credentials and self-propagate. Action: Upgrade immediately (sqlite \>= 2.4.0, postgres \>= 2.3.0, db-service \>= 2.11.0). Assume all local credentials are compromised if you installed the malicious versions.
2. u/beproduct/nestjs-auth worm (CVE-2026-46412)
Threat: Malicious versions containing payloads from the Mini Shai-Hulud npm supply-chain worm campaign were published. Action: Remove and reinstall dependencies. Audit for signs of compromise if installed during the affected window (v0.1.2 - 0.1.19).
3. guardrails-ai compromise (CVE-2026-45758)
Threat: A malicious version of guardrails-ai (0.10.1) was published to PyPI. It has been quarantined. Action: Uninstall guardrails-ai==0.10.1 and reinstall a known good version.
HIGH Severity Highlights
Remote Code Execution (RCE): Both Diffusers (CVE-2026-45804) and lmdeploy (CVE-2026-46517) in the AI/ML ecosystem have vulnerabilities allowing for unsafe remote code execution via trustremotecode bypasses. PenPot MCP (CVE-2026-45805) exposes an unauthenticated /execute endpoint. Denial of Service (DoS): Heavy hitters include u/libp2p/gossipsub (Heap exhaustion), u/libp2p/kad-dht (Disk exhaustion), and SQLFluff (Parser resource consumption). Update to patched versions to prevent node crashing. SSRF & Injection: Crawlee for Python and SillyTavern both suffer from SSRF vulnerabilities requiring configuration updates. samlify is vulnerable to XML injection leading to privilege escalation in signed SAML assertions.

⚠️ HIGH Severity Highlights
Denial of Service (DoS) Wave: Several major packages are vulnerable to crashing today. Parse Server (CVE-2026-47138) can be taken down pre-auth via a regex backtracking attack in the client version header. qs (CVE-2026-8723) will crash on specific null/undefined arrays. u/libp2p packages are vulnerable to both memory and disk exhaustion attacks. AI Toolchain Remote Code Execution: Both Diffusers (CVE-2026-45804) and lmdeploy (CVE-2026-46517) have vulnerabilities bypassing trustremotecode guardrails, allowing arbitrary remote code execution on model fetch. SSRF & Injection: Crawlee for Python and SillyTavern both suffer from SSRF vulnerabilities requiring configuration updates. samlify is vulnerable to XML injection leading to privilege escalation, and js-cookie is vulnerable to a prototype hijacking attack.
