CVE-2025-71379

A flaw was found in vLLM. Multiple regular expression denial of service ReDoS vulnerabilities exist in versions greater than or equal to 0.6.3 and less than 0.9.0. An attacker can exploit this by submitting crafted input with nested or repeated structures to specific regex patterns within vLLM,...

CVE-2025-71379

vLLM versions = 0.6.3 and 0.9.0 contain multiple regular expression denial of service ReDoS vulnerabilities. Several regex patterns — in vllm/lora/utils.py, the phi4mini tool parser, and the OpenAI-compatible serving chat endpoint — are susceptible to catastrophic backtracking. An attacker...
