A basename made of many dots and ending in a backslash makes the regex backtrack in time quadratic in its length.\n\nA remote attacker can exhaust CPU with one request, as a basename of about 32 KB takes several seconds to match and every file part is matched separately."}], "lastModified": "2026-10-29T15:11:53.000", "sourceIdentifier": "9b29abf9-4ab0-4765-b253-1875cd9b441e"}
