CVE-2026-7669
MEDIUM · 5.6Fresh disclosure, no PoC public, no KEV, vendor unresponsive; chatter recycled feeds and speculation.
What: Unsafe deserialization in SGLang's HuggingFace Transformer handler (get_tokenizer function) affecting versions up to 0.5.9. CVSS 5.6 MEDIUM.
Why it matters: Published yesterday with no vendor response, no KEV listing, and no confirmed PoC. Social chatter conflates unrelated authorization bypass claims (NextChat MCP) with the deserialization flaw. High complexity + difficult exploitability per NVD reduce practical risk. Chatter is largely automated feed replication.
Where it's seen: Vuln alert feeds and automated CVE tracking accounts dominating; one speculative post claiming RCE but without supporting evidence or PoC link.
RISK: MODERATE — Unsafe deserialization in ML serving path; high attack complexity and difficult exploitability limit near-term threat.
